JR series wound rotor induction motor is a three-phase asynchronous motor, which was the motor designed by China in the late 1950s, which is divided into low-voltage wound rotor motor and high-voltage wound rotor motor,They are the basic series of medium-sized three-phase asynchronous motors.It can drive a variety of machinery, such as fans, air blowers, air compressors, pumps, crushers, ball mills, cutting machine tools, transport machinery and other equipment for coal, machinery industry, power plants and various industrial and mining enterprises as prime mover use.
JR series wound rotor motor must be connected to the starting rheostat in the rotor circuit before starting. It is not permissible to start the rotor windings directly.
JR series wound rotor ac induction motors allow long term deceleration under reduced torque conditions.
