Product Description

The large-scale high-voltage slip ring motor is a large-scale mechanical equipment motor product developed and manufactured by our company on the basis of years of research and development and manufacture of high-voltage three-phase asynchronous motor. This type of motor adopts box type structure. The frame is made of steel plate welded box structure, which is light in weight and good in rigidity. It can be installed with protective cover or cover on both sides of the frame. After removing the protective cover or cover, the motor can be observed and touched. Internal, easy to maintain and repair the motor.
The stator of the large high-voltage slip ring motor adopts a slide-in external press-fit structure. The stator winding is made of Class F insulation material, and the ends are reliably fixed and bundled. During the manufacturing process, multiple turns of the pulse voltage test and grounding are performed. Withstand voltage test and vacuum pressure impregnation solventless paint process (VPI) treatment, 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 bearing has two types of rolling bearing and sliding bearing. According to the motor power and speed, the basic form of protection is IP54. If the motor has a high degree of protection, the protection level of the bearing will also increase.
The main high-voltage slip ring motor main outlet box is IP54 protection grade, generally installed on the right side of the motor (facing the motor shaft extension end), or can be installed on the left side of the motor according to the order. The main outlet box has a separate external Ground terminal.

This type of motor is suitable for use in environments where the ambient air temperature does not exceed 40 ° C and there is no serious dust, the minimum ambient air temperature is -15 ° C, and there is no corrosive and explosive gas in the air (which can also be made into a damp heat or high-altitude motor).

The large high-voltage 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.).
