JR slip ring motor for ball mill

The JR winding slip ring motor is designed for use with ball mills. This type of motor optimizes the product structure and is a new product that improves process design, maximizing the use of mill equipment.
The mechanical strength of the JR series ball mill motor winding is high, which improves the insulation level of the motor. The slip ring and carbon brush device of the motor are placed outside the end cover, which can effectively prevent the carbon dust from contaminating the coil, and at the same time, it is also easy to replace and repair. In the manufacturing process, the power frequency to ground test of the power pulse tester was carried out several times. The stator and rotor windings were made of Class F insulation varnish and cured by high temperature drying. The insulation performance of the motor was stable and reliable.

The JR ball mill special winding slip ring motor is an improved new product motor that meets the relevant international technical conditions.

JR ball mill motor adopts rotor string resistance full-voltage start-up, which has the advantages of small starting current, large starting torque, high efficiency, low noise, low vibration, good ventilation performance, reliable operation, convenient installation and maintenance.

JR ball mill motors are widely used in mining machinery, such as ball mills, crushers, etc. It can also drive a variety of different machines such as fans, compressors, pumps, cutting machines, transport machinery and other equipment.
