The YRKS large-scale motor is a high-voltage wound-water-cooled three-phase asynchronous motor. The power class, installation dimensions 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.
YRKS large slip ring motor bearings are divided into two types, 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.
YRKS large water cooler motor addition set, bearing temperature measuring device, can also add heating device inside the motor, the shaft extension of the motor uses the tangential key, the motor carbon brush is not lifting structure, the front and rear bearing chambers of the motor have Oil filling and oil draining device.
YRKS large slip ring motor can be used to drive various kinds of 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. Used as a prime mover in an 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.

YRKS large high-voltage wound rotor slip ring motor 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.
Main process flow of the motor
Motor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint drying
Electronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balance
Motor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storage
