YD series multi-speed motors were designed based on Y/Y2 series motors, this type of motors have a single winding, but through change its connection, the motor changed to different poles, thus it runs under different speed and with different output power.

YD series multi-speed motors owns all the advantages that Y/Y2 series motors have, they 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.
