Product Description

JR winding slip ring motor is specially designed for ball mill. This series of motors is a derivative of the original JR slip ring motor. It is a new product that optimizes the product structure and improves the process design, maximally meeting the use of mill equipment.JR series ball mill motor windings have high mechanical strength and improve 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 carbon dust from contaminating the coil, and at the same time, it is easy to replace and repair. In the manufacturing process, the power frequency to ground pressure test of the turn-to-turn pulse withstand tester was carried out. The stator and rotor windings were made of F-grade insulating varnish and cured by high temperature drying. The insulation performance of the motor was stable and reliable.

Motor power range: 80KW-900KW

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.).

 

There are many types of motor products manufactured and sold by our company. The main products are high- and low-voltage three-phase asynchronous motors. The motor structure types include squirrel-cage type and winding type. Among them, high-voltage synchronous motors mainly support air compressors and mine ball mill equipment. use. We adhere to the service tenet of "focus on products, service with heart" and provide high-quality motor products to customers.

 

The company has large-scale laboratory, intelligent CNC winding machine, CNC rising machine, automatic wrapping machine, VPI high pressure vacuum immersion system, large-scale dipping paint drying furnace, 60 tons test platform, large vertical car, milling machine, grinding machine, Each type of dynamic balancing machine, double-feedback test and detection system with 6MW (12MW) motor and other motor production professional equipment more than 500 sets, sound mechanical equipment processing capacity, to lay a good foundation for customers to improve good quality motor products.
