Product Description

HV slip ring motor is a high-voltage wound rotor three-phase asynchronous motor developed and manufactured by our company for many years. This type of motor adopts box structure. The frame is made of steel plate welded box structure, which is light in weight and good in rigidity. There are window holes at the top, which can be installed with a protective cover or cover. After removing the protective cover or cover, you can observe and touch the inside of the motor to facilitate maintenance and repair of the motor.
HV slip ring motor motor stator adopts slide-in external press-fit structure, stator winding resistance adopts Class F insulation material, and the end has reliable fixing and bundling. During the manufacturing process, multiple turns of pulse voltage test and ground pressure resistance are applied. The test is carried out by vacuum pressure impregnation solventless paint process (VPI). Therefore, the motor has excellent insulation performance, good mechanical strength and strong moisture resistance. The wound rotor is treated with Class F insulation and vacuum pressure impregnation solventless paint process (VPI). The rotor weld head and the wiring are all insulated. The slip ring and stator winding of the motor are located in two isolated spaces to prevent toner from entering the winding.

The HV wound rotor slip ring motor can increase the large starting torque at a small starting current. The motor is suitable for applications where the capacity of the feeder line is insufficient to start the squirrel-cage rotor, the starting time is long, the starting is frequent, and the small-range speed regulation is required. This series of motors has the advantages of high efficiency, energy saving, low noise, low vibration, light weight, reliable performance, convenient installation and maintenance.


Main process flow of the motor
Motor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint drying
Electronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balance
Motor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storage


The company insists on providing high-quality motor products and services to users, and has won high praise from many domestic and foreign customers. The company will receive many foreign merchants to visit our factory every year, and establish a good cooperative relationship through on-site inspection of our factory. Our company always welcomes customers to visit our factory.


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.).
