MC series aluminum housing capacitor start 3kw single phase motor is made of selected quality materials and conform to the IEC standard. MC motor has good performance, safety and reliable operation, nice appearance, and can be maintained very conveniently, while with low noises ,little vibration and at the same time of light weight and simple construction. High starting torque, perfect starting performance, generally the multiple of the starting torque can be up to 3.0 times. This motor is used in the occasions where big starting torque and small starting current such as air-compressors, pumps, refrigerators, medical apparatus and others with full-load start.

About motor
Motor performance index requirements
1. Efficiency level Efficiency is one of the most important technical and economic indicators of a motor, which directly affects the amount of effective materials and operating costs of the motor. Higher operating efficiency can bring significant energy-saving effects to users, but the increase in the amount of effective materials for motors will increase the cost and selling price. At the same time, whether the higher efficiency can fully play a role is also related to the annual running time of the motor and the load rate during running.
2. The operating load rate of low-voltage asynchronous motors is generally between 50% and 80%, mostly in the range of 60% to 70%. The change of asynchronous motor efficiency at different load rates is related to the distribution ratio of variable loss (copper loss of stator and rotor windings) and constant loss (iron loss and mechanical loss) of the motor. In the total loss, the variable loss increases. The constant loss is reduced, and the highest efficiency appears closer to the low load rate area. Therefore, when designing the motor, if the electromagnetic load is appropriately increased, the variable loss will increase, and the constant loss should be controlled as much as possible. This can make the motor have a relatively flat efficiency characteristic in a relatively wide load rate range. It is beneficial for the motor to still have a higher efficiency at a relatively low load rate.
