Product Description

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.

Motor power range: 95KW-780KW
Rated voltage: 380V/415V/660V/690V/3000V/33000V/6000V/10000V

The deviation of the rated voltage of the JR ball mill motor does not exceed 5%, the allowable deviation of the frequency is 1%, and the sum of the absolute values of the deviations does not exceed 5%.

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 and convenient installation and maintenance.


1. The outer packaging of the products are all standard export-oriented wooden plywood packaging.
2, the product packaging is protected by moisture, water plastic soft packaging
3. For products with special transportation requirements (such as temperature, fragile, variability, and easy to get wet), the packaging protection measures will be strengthened, and the target mark will be printed on the package.
4. There are obvious signs and symbols on the packing box that must be paid attention to during transportation and storage (such as position, moisture, rain, shockproof, lifting position, etc.).
