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.

The wound rotor motor is a slip ring three-phase asynchronous motor. The power rating, installation dimensions and electrical performance of this type of motor comply with the relevant IEC standards. The basic installation method of the motor is the horizontal bottom angle (IMB3), the working system is the continuous working system (S1), and the wound rotor is made of Class F insulation material.

The winding rotor motor has two types of bearings: rolling bearing and sliding bearing, depending on the motor power and speed. The rated frequency of the motor's power supply is 50Hz, the rated voltage is 6000V/10000V, and the basic type of protection is IP54. The motor slip ring housing can be protected to IP22 or IP23. Other voltage, frequency and degree of protection motors are also available upon request.

Wound rotor motors can be used to drive a variety of different machinery, such as compressors, pumps, crushers, cutting machine tools, transportation machinery and other mechanical equipment, in mining, machinery industry, petrochemical industry, power plants and other industrial and mining enterprises. Used as the prime mover. The motor used to drive the blower, coal mill, rolling mill and winch should indicate the purpose and technical requirements when ordering, and adopt special design to ensure reliable operation.

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).

Feature of Product

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.
