Product Description

The Wound Rotor Motor is a high-pressure slip ring 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 windows on both sides and top of the frame. Holes, 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 the maintenance and repair of the motor.
The rotor of the wound rotor motor adopts a sliding-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 the ground pressure test are carried out. And vacuum pressure impregnation solventless paint process (VPI) treatment, therefore, the motor's insulation performance is excellent and reliable, mechanical strength is good, moisture resistance is strong. 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 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 outlet box of the wound rotor motor is IP54 protection grade. It is usually installed on the right side of the motor (facing the motor shaft extension). It can also be installed on the left side of the motor according to the order. There is a separate grounding inside the main outlet box. 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 wound rotor motor is a slip-surrounding three-phase asynchronous motor, which can increase the 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.


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.


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.).


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.
