Product Description

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.

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.
