JR series 6KV three-phase asynchronous motor is a wound rotor three-phase asynchronous motor, which complies with JB564-64 specifications. This series is protective type, it can be made pipe ventilation according to the needs of users. The series motor must be connected to the starting rheostat in advance in the rotor circuit.
The rotor winding is not allowed to start directly.
This series motor is designed according to the user’s need for large-capacity low-voltage three-phase winding asynchronous motors.
Large capacity, large start-up load, can provide a large starting torque at a small starting current, and can be added in the rotor circuit to change the speed of the torque.
The motor can be used under heavy start-up load, when it is necessary to install a variable-speed drive, insufficient power distribution capacity, and the squirrel-cage rotor motor cannot be started smoothly or when other electrical equipment is adversely affected, which could use this kind motor, It can drive different machinery such as blowers, compressors, pumps, crushers, ball mills and other equipment. It can serve as the prime movers in coalmines, machinery industry, power plants and various types of industrial and mining enterprises.
