The large high-voltage slip ring motor is a wound-type 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 wor ept system is the continuous wor ept system (S1), and the wound rotor is made of Class F insulation material.
Large high-voltage 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.
Large-scale high-voltage slip ring motor increases the setting and bearing temperature measuring device. It can also add heating device inside the motor. The shaft extension of the motor generally uses tangential keys. The motor carbon brush is not lifting structure. The front and rear bearing chambers of the motor are all There are oil filling and oil draining devices.
Large high voltage wound rotor slip ring motors can be used to drive a variety of different machines, such as compressors, pumps, crushers, cutting machines, transport machinery and other mechanical equipment, in the mining, machinery industry, petrochemical industry, power plants It is used as a prime mover in various industrial and mining enterprises. 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).
The large high-voltage wound rotor slip ring motor can increase the large 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 ma ept → 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
The company has large-scale laboratory, intelligent CNC winding machine, CNC rising machine, automatic wrapping machine, VPI high pressure vacuum immersion system, large-scale dipping paint drying furnace, 60 tons test platform, large vertical car, milling machine, grinding machine, Each type of dynamic balancing machine, double-feedback test and detection system with 6MW (12MW) motor and other motor production professional equipment more than 500 sets, sound mechanical equipment processing capacity, to lay a good foundation for customers to improve good quality motor products.
1. The outer packaging of the products are all standard export-oriented wooden plywood packaging.
2, the product packaging is protected by moisture, water plastic soft packaging
3. For products with special transportation requirements (such as temperature, fragile, variability, and easy to get wet), the packaging protection measures will be strengthened, and the ept mark will be printed on the package.
4. There are obvious signs and symbols on the pac ept box that must be paid attention to during transportation and storage (such as position, moisture, rain, shockproof, lifting position, etc.).
