1.Brief introduction
YR series wound rotor three phase asynchronous motor is new series motor developed according to IEC standard. Superior matrerials and elaborate construction enable the motor has such advantage as high-efficiency, energy-saving, low noise and vibration, high reliablity, easy mounting and maintenance etc.


YR series slip ring motor is applicable to driving universal machines such as compressors, blowers, pumps, crusher etc. And they are widely used in mining industry, mechanical industry, chemical industry, generating plant, etc.
