YY71-2 110V 800W Portable Concrete Mixer Motor: Reliable Power for North American Mixing Applications

Portable concrete mixers require a motor that can deliver dependable starting performance, consistent torque, and stable operation in demanding work environments. The motor must be compact enough for portable equipment while also providing sufficient power to rotate a loaded drum, paddle, or mixing assembly. It must tolerate repeated starts, variable loads, dust, vibration, and long working cycles without excessive heating or premature wear.

The YY71-2 110V 800W Portable Concrete Mixer Motor is designed to meet these practical requirements. With an 110V operating voltage, 800W rated power, 50/60Hz frequency compatibility, and a high-speed two-pole design rated at approximately 2,800 revolutions per minute, it is suited to portable concrete mixers used in North American household, renovation, landscaping, and job-site applications.

Its plug-and-play 110V configuration eliminates the need for a voltage transformer in compatible North American electrical environments. The motor combines high-power output, pure copper windings, low-loss operation, smooth starting under load, and a structure intended for straightforward installation and maintenance. These characteristics make it a practical alternative to undersized motors that may struggle with loaded starting, experience excessive heat, or require frequent service.

Product Overview

The YY71-2 is a concrete mixer motor developed for portable mixer equipment with an approximate working capacity of 120 to 180 liters. Its 800W output provides a useful balance between power, portability, and energy consumption. The motor is intended for applications that need stronger torque and faster mixing performance than a small household motor can provide, without moving to a much larger industrial drive system.

The motor operates at 110V and supports both 50Hz and 60Hz power frequencies. This frequency range increases installation flexibility and makes the model suitable for a broad range of compatible electrical systems. Before installation, the user should always confirm the mixer design, supply characteristics, mounting dimensions, shaft configuration, and protection requirements.

The two-pole design produces a nominal speed of approximately 2,800 RPM. In a complete mixer assembly, the final drum or paddle speed will depend on the gearbox, belt drive, chain drive, pulley ratio, and mechanical transmission used by the equipment manufacturer. The motor therefore serves as the high-speed power source, while the mixer’s reduction system converts motor speed into the slower rotational speed required for effective concrete mixing.

Why Motor Selection Matters in Portable Concrete Mixers

A portable concrete mixer may appear mechanically simple, but its motor experiences a challenging combination of conditions. The drum or mixing blades must overcome static resistance at startup, the weight of the material inside the drum, friction in bearings and transmission components, and the changing load created as aggregate, cement, and water move through the mixing chamber.

Starting a mixer with an empty drum is relatively easy. Starting or restarting with a partially loaded drum is more demanding. A motor with insufficient output may fail to accelerate the load, draw excessive current, produce excessive heat, or trip protective devices. Repeated unsuccessful starts can reduce motor life and interrupt the work schedule.

Once the mixer is operating, the motor must maintain stable rotation as the material moves. Concrete ingredients do not create a perfectly constant load. The resistance changes as the mixture becomes heavier, more cohesive, or unevenly distributed. A suitable motor must therefore combine adequate rated power with the ability to provide useful torque throughout normal operating conditions.

The motor also works in environments where dust, vibration, and transportation are common. Portable mixers are frequently moved between construction areas, stored in workshops, or operated outdoors. A motor selected for this equipment should be mechanically dependable, thermally stable, and simple to inspect and maintain.

800W Output for Stronger Mixing Performance

The 800W rating gives the YY71-2 a substantial power reserve for compatible portable mixer applications. Compared with lower-powered motors intended for light-duty equipment, an 800W motor can provide stronger driving capability when the mixer starts under a practical working load. This is especially important when the drum contains aggregate or when the mixture has begun to thicken.

Higher rated power does not mean that the motor should be overloaded. Instead, it provides a more appropriate operating margin when the mixer is correctly matched to the motor. A motor with adequate capacity can operate closer to its intended working range rather than being forced continuously toward its limit. This can contribute to smoother operation, reduced thermal stress, and more consistent mixing.

The 800W specification is also useful for equipment designers seeking a balanced motor package. A motor that is too small may offer a lower initial cost but can create performance problems and service complaints. A motor that is unnecessarily large may increase equipment size, weight, energy use, and manufacturing cost. The YY71-2 is positioned as a practical middle-range solution for portable mixers in the approximate 120–180L class, provided that the mixer’s transmission and duty cycle are properly designed.

For manufacturers, distributors, and replacement-part suppliers, the power rating provides a clear basis for product matching. It allows the motor to be evaluated against drum capacity, transmission ratio, expected material density, start frequency, and operating duration. Correct matching remains essential, but a clear 800W specification simplifies the initial selection process.

110V Plug-and-Play Compatibility

One of the main advantages of the YY71-2 is its 110V configuration. Many portable mixers used in North American homes, workshops, renovation projects, and job sites are expected to connect directly to compatible local power supplies. A motor designed for 110V operation can reduce installation complexity because a separate step-down transformer is not required when the available supply and equipment wiring are suitable.

Removing the transformer from the standard installation arrangement can provide several practical benefits. It may reduce the number of components in the equipment, save space, simplify wiring, reduce total system weight, and make replacement easier. A simpler power arrangement can also help maintenance personnel identify faults more quickly.

Plug-and-play compatibility should always be understood within the limits of the complete machine. The mixer should include appropriate switching, overcurrent protection, grounding, cable sizing, and enclosure protection. The motor must be connected according to the approved electrical design, and the supply should be verified before commissioning. Direct 110V compatibility is an equipment advantage, but it does not replace proper electrical safety procedures.

For North American equipment manufacturers and replacement-market suppliers, the 110V configuration can be particularly useful. It allows a motor to be specified for products intended for common low-voltage commercial and household environments without requiring a complex voltage-conversion package.

Pure Copper Windings and Electrical Efficiency

The YY71-2 uses pure copper windings. Copper is widely valued in motor construction because it combines strong electrical conductivity with reliable thermal performance. A winding made with suitable copper conductors can transfer electrical energy into magnetic force with relatively low resistance losses when correctly designed and manufactured.

Lower winding resistance helps reduce energy lost as heat during operation. This can support more stable running temperatures, especially when the motor is working continuously or repeatedly under load. Reduced heat generation may also help protect insulation and other internal components from unnecessary thermal stress.

Pure copper windings can contribute to efficient current transfer and consistent electromagnetic performance. For a concrete mixer, this is relevant because the motor must maintain dependable rotation during changing loads. Stable winding characteristics help the motor respond more predictably as the mechanical resistance rises and falls.

Winding material alone does not determine total motor quality. Performance also depends on conductor size, winding arrangement, insulation system, lamination design, rotor balance, bearings, assembly accuracy, and quality-control procedures. The value of the YY71-2 lies in the combination of pure copper winding construction with a power level and speed configuration intended for portable mixer service.

For equipment owners, the practical benefit is a motor designed to operate with lower heat and lower loss under suitable working conditions. For manufacturers, copper winding construction supports the development of a motor that can deliver consistent performance while meeting the expectations of professional and commercial users.

High-Speed Two-Pole Design

The YY71-2 uses a two-pole high-speed design with an approximate rated speed of 2,800 RPM. High motor speed allows the motor to deliver its power through a compact body while working with a reduction transmission designed for the mixer. This arrangement is common in equipment where the motor must remain relatively small but still drive a larger, slower-moving mechanism.

The motor’s speed should not be confused with the final speed of the mixer drum. Concrete must be mixed at a controlled drum speed that allows the ingredients to lift, fall, fold, and combine. The mixer’s gearbox, belt system, or other transmission reduces the motor speed to the appropriate drum speed. The two-pole motor provides the input speed, while the machine’s mechanical design determines the final mixing motion.

A high-speed motor can support a compact equipment layout and efficient power transmission when correctly matched with the reduction system. It may also simplify replacement in machines that already use a high-speed motor and mechanical reducer. However, the drive ratio, pulley alignment, belt tension, bearing capacity, and cooling conditions must all be verified during installation.

The approximately 2,800 RPM figure is a nominal specification. Actual operating speed can vary according to frequency, load, supply conditions, slip, and motor design. Users should rely on the complete equipment specification when determining drum speed and production capacity.

Smooth Starting Under Load

Starting performance is one of the most important characteristics of a concrete mixer motor. A mixer may be stopped while material remains inside the drum, either because of a temporary interruption, a power issue, or a normal work-cycle pause. When restarted, the motor must overcome the static resistance of the partially loaded drum and transmission.

The YY71-2 is designed to provide smoother starting under load than a motor that is poorly matched to the application. Its 800W output and application-focused configuration support stronger initial driving performance. A smoother start can reduce mechanical shock transmitted through the shaft, couplings, belts, gears, and drum supports.

Reduced starting shock may help improve the working life of connected components. It can also make the mixer feel more stable during operation and reduce the likelihood of abrupt movement. Smooth starting is particularly useful in small job-site mixers, where the machine may be started and stopped frequently throughout the day.

Actual starting performance depends on the supply circuit, motor protection, temperature, load condition, transmission design, and condition of the mixer. The motor should not be used to compensate for a jammed drum, damaged bearing, over-tight belt, incorrectly adjusted gearbox, or load beyond the mixer’s rated capacity. Proper mechanical maintenance remains essential.

Thermal Stability and Continuous Operation

Concrete mixing work can involve repeated cycles or extended operation. Excessive motor temperature is a common cause of reduced service life because heat can affect winding insulation, bearings, lubricants, and other components. A motor designed for stable thermal behavior is therefore valuable in professional equipment.

The YY71-2 is described as having low heat and low loss characteristics when operated within its intended conditions. The pure copper winding supports efficient electrical performance, while appropriate motor construction and assembly help control heat generation. Stable continuous operation can reduce interruptions caused by overheating and can improve the overall reliability of the mixer.

Thermal performance also depends on the installation environment. The motor must have sufficient ventilation, and cooling openings should not be blocked by dust, protective covers, or nearby equipment. The mixer should be installed so that airflow can reach the motor as intended. Operation in extremely hot locations, direct sunlight, or enclosed areas may reduce cooling effectiveness.

Users should also consider duty cycle. A motor rated for a particular application should be operated according to the equipment manufacturer’s instructions. Continuous heavy loading, repeated overloads, frequent stalled starts, or operation with a jammed mixing mechanism can cause overheating even when the motor is correctly rated for normal service.

When used in a properly designed portable mixer, the YY71-2’s thermal characteristics can support dependable operation across repeated mixing cycles. This is an important advantage over low-cost motors that may deliver acceptable performance only under light or intermittent loads.

Low Noise and Stable Performance

Noise is an important consideration for portable mixers used near homes, small businesses, workshops, and occupied job sites. Some operating sound is unavoidable because the mixer contains a motor, transmission, drum, and moving material. However, a stable motor can help prevent unnecessary vibration, rattling, and irregular mechanical noise.

The YY71-2 is designed for low-noise operation. Its motor performance can contribute to a more comfortable working environment when combined with correct installation, balanced components, suitable bearings, and proper belt or gear adjustment. Lower motor noise may also make it easier for operators to identify abnormal sounds from the drum or transmission.

Noise reduction is not created by the motor alone. Loose mounting bolts, misaligned pulleys, worn bearings, damaged gears, incorrect belt tension, and unbalanced drums can all increase sound levels. The motor should therefore be installed on a rigid, accurately aligned mounting structure, and the entire mixer should be inspected regularly.

Stable performance is equally important. A motor that maintains consistent operation helps the mixer deliver a more uniform mixing process. Stable rotation can reduce sudden changes in drum movement and support predictable work cycles, which is valuable for both professional users and occasional operators.

Suitable Applications

The YY71-2 is intended primarily for portable concrete mixers in the approximate 120–180L range. Such mixers are commonly used for small construction tasks, home renovations, foundation repairs, landscaping projects, fence installations, paving work, masonry, and general maintenance.

The motor may also be suitable for replacement applications where the original motor has the same electrical, mechanical, and performance requirements. Replacement suitability must be confirmed carefully. Voltage, power, speed, shaft dimensions, mounting holes, rotation direction, terminal arrangement, motor body size, and transmission compatibility should all match the equipment design.

Typical application environments may include:

Residential construction and repair projects that require a portable source of mixed concrete.

Small contractor operations where equipment is transported between multiple work locations.

Landscaping projects involving footings, retaining walls, posts, paths, and hardscape structures.

Workshops and rental fleets that need a durable and serviceable mixer motor.

Equipment manufacturers developing compact mixers for North American markets.

Maintenance and replacement programs for compatible 110V portable mixer systems.

The motor is not automatically suitable for every mixer with a similar physical size. Heavy industrial mixers, oversized drums, high-viscosity processing equipment, and machines with unusually demanding duty cycles may require a different motor specification. Application engineering should be completed before purchase or installation.

Advantages Over Undersized or Poorly Matched Motors

The YY71-2 offers several practical advantages when compared with a motor that is too small or not designed for the demands of concrete mixing. The first is its 800W power level, which provides a stronger operating foundation for a 120–180L portable mixer. An undersized motor may struggle to start a loaded drum and may remain close to its thermal limit during normal operation.

The second advantage is the 110V configuration for compatible North American equipment. A motor requiring an unsuitable voltage may need additional conversion equipment, creating extra weight, wiring, cost, and potential failure points. A correctly specified 110V motor simplifies the power arrangement.

The third advantage is the use of pure copper windings. In comparison with lower-quality construction using inferior conductive materials or inconsistent winding processes, copper windings can support lower electrical losses and more reliable heat management.

The fourth advantage is the high-speed two-pole format. This provides a useful motor speed for equipment fitted with a reduction gearbox or belt transmission. It can help maintain a compact motor package while delivering the input speed required by the mixer’s drive system.

The fifth advantage is service practicality. A motor that is easy to install and maintain can reduce downtime. Portable equipment often operates under time pressure, and a replacement motor that can be integrated into the existing system with minimal modification is valuable to contractors, rental companies, and repair technicians.

These advantages should be evaluated together rather than individually. A strong motor cannot correct an incorrectly designed transmission, and a copper winding cannot compensate for overloading. The best results come from matching the motor to the mixer’s capacity, drive system, electrical supply, and expected duty cycle.

Manufacturing Strengths and Quality-Oriented Production

Shengzhou Jiangxin Motor Technology Co., Ltd. was established in 2017 and focuses on the research, development, production, and sale of AC/DC motors and micro motors. The company is based in Shengzhou, Zhejiang Province, within the Yangtze River Delta industrial region. This location provides access to a mature manufacturing network, engineering resources, component suppliers, logistics infrastructure, and technical labor.

The company operates modern production facilities and uses advanced automated equipment. Automation can improve repeatability in processes such as component assembly, winding, testing, balancing, and inspection. Consistent production is particularly important for motors because small differences in winding placement, rotor balance, bearing installation, or electrical connections can influence noise, heat, efficiency, and service life.

A professional research and development team supports product improvement and application customization. This capability is valuable for motor customers who need more than a standard catalog item. Equipment manufacturers may require adjustments to mounting structure, shaft design, electrical configuration, speed, protection, or other characteristics. An experienced development team can help evaluate these requirements and determine whether they are technically and economically practical.

The company has been recognized as a provincial-level technology enterprise. This recognition reflects an emphasis on technical development and innovation. For customers, a technology-oriented manufacturing partner can offer greater confidence when developing new equipment or improving an existing motor platform.

Quality control is presented as a core part of the manufacturing approach. A reliable motor requires control of incoming materials, winding processes, assembly accuracy, electrical testing, mechanical inspection, and finished-product performance. Quality systems help identify variation before products reach the customer and create a basis for continuous manufacturing improvement.

The company’s product range includes evaporative air cooler motors, industrial heater motors, oil pump motors, customized motors, and other AC/DC motor solutions. This range indicates experience across different operating environments and application requirements. Knowledge gained from cooling equipment, heating systems, hydraulic applications, and other machinery can support the development of practical motor solutions for portable mixers.

Advanced Production Processes

A motor’s performance is the result of multiple manufacturing stages working together. The first stage is material preparation. Electrical steel laminations, copper wire, insulation materials, bearings, shafts, housings, fasteners, and other components must meet the required specifications. Consistent materials provide the foundation for stable electrical and mechanical performance.

The winding process is especially important. Copper wire must be arranged accurately in the stator slots, with suitable tension, spacing, insulation, and connection quality. A controlled winding process can help ensure that the motor produces the intended magnetic field and avoids localized heating. Automated or semi-automated winding equipment can improve repeatability while production personnel monitor process parameters.

Insulation treatment protects the winding from electrical breakdown and helps maintain reliability under heat and vibration. Insulation materials and curing procedures must be compatible with the motor’s operating temperature and duty requirements. Proper treatment also helps secure the winding so that it does not move excessively during starting or operation.

Rotor assembly requires attention to shaft accuracy, lamination placement, balance, and air-gap uniformity. An imbalanced rotor can increase vibration and noise, place additional loads on bearings, and reduce service life. Accurate assembly and balancing support smooth rotation at the approximately 2,800 RPM operating speed of the YY71-2.

Bearing installation must also be controlled carefully. Bearings that are misaligned, contaminated, damaged, or improperly fitted can create friction and heat. Correct bearing selection and assembly help the motor transfer power efficiently and maintain stable operation.

Electrical testing can include resistance checks, insulation testing, voltage testing, current measurement, and no-load performance verification. These tests help identify winding faults, connection problems, insulation defects, and abnormal electrical behavior. Mechanical testing may include rotation checks, noise evaluation, vibration inspection, and operating-temperature observation.

Final inspection ensures that the completed motor conforms to the required appearance, dimensions, electrical specifications, and packaging standards. A structured production process reduces variation between units and supports dependable integration into customer equipment.

Engineering for Practical Maintenance

Portable concrete mixer motors operate in environments where maintenance access may be limited. A practical motor design should allow technicians to inspect connections, clean ventilation areas, check mounting hardware, and diagnose performance problems without unnecessary disassembly.

The YY71-2 is designed for easy installation and maintenance. This is important for contractors and rental operators because equipment downtime can affect schedules and operating costs. A motor that can be replaced or serviced efficiently helps return the mixer to operation more quickly.

Routine maintenance should include checking motor mounting bolts, inspecting electrical terminals, cleaning dust from ventilation areas, examining the power cable, checking the transmission alignment, and listening for unusual noise. The mixer drum and gearbox should also be inspected because a mechanical problem can overload an otherwise healthy motor.

Operators should disconnect the power supply before opening electrical covers or working near rotating components. Repairs should be performed by qualified personnel using suitable tools and replacement parts. Safety procedures are essential because the motor operates from a potentially hazardous electrical supply and drives components capable of causing injury.

Good maintenance begins with correct installation. The motor should be mounted securely, aligned with the transmission, and protected from direct water exposure. Cables should be routed away from moving parts and sharp edges. If the machine uses belts, belt tension should follow the equipment manufacturer’s instructions. Excessive tension can overload bearings, while insufficient tension can cause slipping and heat.

Installation and Equipment Matching

Before installing the YY71-2, confirm that the complete mixer is designed for an 110V, 800W motor operating at 50/60Hz. The replacement motor should have compatible mounting holes, shaft dimensions, shaft length, rotation requirements, and electrical connections. Physical similarity alone is not enough to establish compatibility.

The transmission ratio should be evaluated to ensure that the mixer drum or paddle operates at its intended speed. The motor’s approximate 2,800 RPM speed is the motor-side value. The final mixer speed must remain within the limits specified by the equipment manufacturer.

The electrical supply should be capable of supporting the motor’s starting and running requirements. Wiring, switches, plugs, protective devices, and grounding systems should be appropriately rated. A qualified electrician or equipment technician should verify the installation when necessary.

After installation, the motor should first be tested without material in the drum. The technician should observe the direction of rotation, listen for abnormal sounds, check for excessive vibration, and confirm that the motor accelerates smoothly. The mixer can then be tested with a light load before progressing to its normal operating condition.

If the motor becomes unusually hot, trips protection, produces smoke, vibrates excessively, or fails to start, operation should stop immediately. Possible causes include an overloaded drum, incorrect wiring, a jammed transmission, incorrect voltage, insufficient ventilation, damaged bearings, or a defective component. Continuing to operate under abnormal conditions may cause additional damage.

Operational Best Practices

To obtain the best performance from the YY71-2, users should avoid loading the mixer beyond its rated capacity. The approximate 120–180L application range is a guide based on compatible equipment design, not permission to exceed the mixer’s actual material limit. Aggregate size, mixture density, water content, drum geometry, and mixing time all influence motor loading.

Materials should be introduced according to the mixer manufacturer’s recommended sequence. Sudden loading of a large quantity of dry aggregate or cement can create an unnecessary torque peak. A controlled loading process helps the motor and transmission reach stable operating conditions.

The drum should not be allowed to remain stalled with power applied. If the mixer stops, disconnect the power and determine the cause before restarting. Never attempt to clear a jam while the motor is energized.

Operators should allow appropriate cooling time if the equipment is used for repeated heavy cycles. Ventilation openings should remain clean, and the motor should not be covered with materials that restrict airflow. The mixer should be stored in a dry, protected location when not in use.

These practices complement the motor’s built-in advantages. Even a well-manufactured motor can be damaged by persistent overloading, poor ventilation, incorrect wiring, or mechanical obstruction.

Value for Equipment Manufacturers and Distributors

For manufacturers of portable concrete mixers, the YY71-2 offers a clearly defined motor platform with specifications that are easy to integrate into product planning. The 110V rating supports North American equipment designs, while the 800W output provides a practical power level for compact mixing equipment. The two-pole, high-speed configuration can be paired with a suitable reduction drive to achieve the required drum performance.

A standard motor platform can simplify purchasing, inventory management, assembly, and service documentation. Manufacturers can develop a consistent machine design around the motor’s electrical and mechanical characteristics, reducing the number of different motor variants required for production or replacement support.

Distributors can also benefit from a product with a clear application position. The motor is not presented as a universal drive for every type of machinery. Instead, it is directed toward compatible portable concrete mixers and related replacement needs. Clear application positioning helps distributors advise customers and reduces the risk of inappropriate selection.

The supplier’s ability to produce customized motors can be valuable when a standard model requires adaptation. Customers may need different mounting arrangements, shaft details, terminal configurations, or other design adjustments. Technical communication between the buyer and manufacturer is essential so that any customized version is validated against the complete mixer system.

International export experience is another strength. The company’s products are exported to more than 60 countries and regions. This indicates familiarity with overseas customer requirements, packaging, communication, production coordination, and export logistics. For global buyers, such experience can support smoother cooperation from sample evaluation through volume production.

Comparison with Alternative Motor Approaches

Several motor approaches may be considered for portable concrete mixers. A smaller low-power motor may reduce the initial equipment cost, but it can offer limited starting capability and may operate near its thermal limit. This approach may be acceptable for very small, lightly loaded mixers, but it is less suitable when the equipment must handle a more demanding 120–180L application.

A higher-power motor may provide additional capacity, but it can increase size, weight, cost, energy consumption, and electrical requirements. If the mixer’s transmission and structure do not need the extra capacity, a larger motor may not provide a proportionate benefit.

A motor using an unsuitable voltage may require a transformer or additional electrical equipment. This can complicate the machine and create additional maintenance considerations. The 110V configuration of the YY71-2 is advantageous where the equipment is intended for compatible North American power supplies.

A motor with lower-quality winding materials may have higher losses or less consistent thermal performance. Pure copper windings provide a stronger basis for efficient electrical operation when combined with appropriate manufacturing control.

A motor with an incompatible speed may require changes to the drive system. The YY71-2’s approximately 2,800 RPM high-speed design is suitable for mixer systems that use an appropriate reduction transmission. The correct choice depends on the complete equipment architecture rather than motor speed alone.

In this context, the YY71-2 represents a balanced solution. It is designed to offer sufficient power without unnecessary oversizing, direct 110V compatibility for suitable markets, copper winding construction, a practical high-speed format, and service-friendly integration.

Quality, Reliability, and Long-Term Use

Reliability is not simply the ability to run once at the rated power. It is the ability to perform repeatedly across the expected life of the equipment while maintaining acceptable temperature, noise, vibration, and electrical behavior. The YY71-2 is designed with this broader view of reliability.

Its copper winding, stable operating characteristics, and low-loss design support dependable performance during normal use. The motor’s suitability for continuous or repeated operation depends on the mixer’s duty cycle and operating conditions, but the product is intended to provide a solid foundation for this type of equipment.

Long-term reliability also depends on the supplier’s production capabilities. Modern facilities, automated equipment, professional research and development, and quality-control systems can help maintain consistent product performance. A manufacturer that works across several motor categories can also apply broader technical knowledge to product development and problem solving.

For customers, reliability has direct economic value. Fewer unexpected stoppages can improve productivity. Easier maintenance can reduce labor time. Stable operation can protect the mixer’s transmission and connected components. A motor with suitable capacity can also reduce the risk of premature failure caused by chronic overloading.

These benefits are most effectively realized when the motor is correctly selected, installed, operated, and maintained. Product quality and equipment discipline work together to determine final service performance.
