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.

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.


Our company's motor manufacturing factory adheres to the concept of green, efficient and energy-saving production service, pays attention to the harmonious development of internal and external environment, builds environmentally friendly motor manufacturing enterprises, strictly implements motor standard process, and selects high-quality energy-saving materials to ensure the quality of motor products.


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.).
