Slip ring rotor motor, also known as three-phase wound rotor AC asynchronous motor, is a rotating motor. It consists of two parts: stator and rotor. The stator is composed of several coils and iron core, and the rotor is composed of brushes, shaft and rotor coil. It is based on electromagnetic induction and electrodynamics. When current passes through the stator coil, a rotating magnetic field is generated, and the rotor coil begins to rotate under the action of electromagnetic induction force.
【Product Advantages】
Stable Operation
The slip ring rotor motor has a well-balanced rotor, with an operating vibration amplitude of 0.05-0.1 mm, and a failure rate that is about 30% lower than that of ordinary motors.
Durable
The slip ring rotor motor uses high-quality conductive materials (conductivity of more than 98%) and wear-resistant bearings (hardness 2-3 times higher than ordinary bearings), which can cope with harsh working conditions and has a service life of 10-15 years.
Accurate Speed Control
The slip ring rotor motor is equipped with a high-precision speed control system with a speed control accuracy of ±0.5%.
Function and use of slip ring rotor motor
High-voltage wound motors are widely used as prime movers in steel, metallurgy, electric power, cement, petroleum, chemical industry, water conservancy, papermaking, sugar, urban water supply and sewage and other related enterprises to drive various machinery, such as ventilators, Induced draft fans, blowers, water supply pumps, sewage pumps, reducers, compressors, coal mills, rolling mills, winches, hoists, shears, crushers, mixers, cutting machinery, transportation machinery and other equipment.
Slip Ring Rotor Motor produced by Milestone Motor has just been exported to Uzbekistan and applied to oil companies.
After receiving the motor, the customer praised the beautiful shell and high quality of the motor. And sent a lot of Slip Ring Rotor Motor replacement projects, expressing the desire to cooperate with Milestone Motor for a long time.
