General introduction：

Y3 series three-phase asynchronous motors, developed with new techniques.

Y3 series motors are defined as totally enclosed, fan cooled, squirrel cage type and noted for their novel design, beautiful model, compact structured, low noise, high efficiency, large torque,  excellent starting performance, easy serving, etc.The motors are  adopted with  F class insulation and designed with assessing method for insulation system according to international practice, it enhances greatly have reached an international advanced level of the same kind of products at the initial days of the 90s.                                                                                                                                         

 Y3 series motors can be widely used as driving equipments of various machineries, such as machine tools, blowers, pumps, compressors, transporters, agricultural andfood processing.Pedestal installation size and centre height and other indexes of the motor completely measured by Y3 series three-phase asynchronous motor.
