Product Description

The high-voltage mill motor is a high-voltage wound-type three-phase asynchronous motor specially made for the mill equipment. The power class, installation size and electrical performance of this type of motor are in compliance with 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 bearings of high-voltage mill motors are available in both rolling and plain bearings, 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.
The high voltage mill motor motor is used to drive the grinding machinery. At the same time, it can also be used to drive other different machinery, such as compressors, pumps, crushers, cutting machine tools, transportation machinery and other mechanical equipment. It is used in various industrial and mining enterprises such as mining, machinery industry, petrochemical industry and power plants. Motivation. 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.
