The three-phase slip ring motor is a wound three-phase asynchronous motor. 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 the three-phase slip ring motor are in the form of rolling bearings and sliding bearings, depending on the power and speed of the motor. 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.
High-voltage three-phase slip ring 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 the mining, machinery industry, petrochemical industry, power plants, etc. Used as a prime mover in a mining and mining enterprise. 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).
Comparison of different series High Voltage motors

The three-phase high-voltage slip ring motor adopts a box structure, and the machine base is welded by steel plates, which is light in weight and good in rigidity.
The high-voltage three-phase slip ring motor is a closed-structure motor with an air-to-air cooler at the top. The stator winding adopts Class F heat-resistant insulating material, and the top binding is reliable, and the vacuum pressure immersion paint makes the motor have good insulation performance and mechanical strength.
The rotor of the high voltage three-phase motor uses a winding structure of a copper conductor. Bearings are available in both rolling and plain bearings, depending on the speed and power of the motor.
