      YD series change-pole multi-speed three phase induction motors are one of the derived series of Y series three phase asynchronous motors, motors of this series have a single winding, through change the connection of wires, the motor changed to different poles, thus it runs under different speed and with different output power.

       YD series motors have lots of futures such as large starting torque, excellent performance, low noise and vibration, high reliability, easy operation and etc. YD series motors are widely used in the mechanism which needs stepped-speed adjustment, such as compressors, machining equipments, transportation system, agricultural mechanism, food processing mechanism etc. We also supply special designed multi-speed motors according to customer’s unique requirements.

        Operating conditions of YD series motors are the same as Y series three phase asynchronous motors.
