Product Details

YKK Series HV three phase squirrel cage AC electric motor

1.Description:

YR series medium size high voltage 3 phase asynchronous slip ring wound rotor motors are high in efficiency, reliable in operation and easy to mount and maintain. This series motors are also advanced in mechanical, electrical and insulation performance, and high technology in manufacturing.

YR series High Voltage Slip ring Wound rotor motor are used to drive compressor, ventilator, water pump, breaker, cutting machine, grinding mill and other general purpose machines.

The frame of motor is welded by steel plates to be formed a box-type.

The rotor winding of YR series High Voltage Slip ring Wound rotor motor is made of copper bar wrapped, with class F insulation.

The High Voltage Slip ring Wound rotor motor is designed to use rolling bearing with grease lubrication or sliding with diluted oil lubrication. The oil can be charged and discharged conveniently.
