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 structure, 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, in 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 and food processing. Pedestal installation size and center height and other indexes of the Y3 three-phase asynchronous motor have reached regular standard.
