Slip Ring Motor

The slip ring motor, also known as the three-phase wound rotor AC asynchronous motor, must be connected in series resistor or reactor in the motor rotor loop, so that the starting current can be reduced, and the starting torque can be increased, the power factor can be improved, and the motor starting performance can be effectively improved. Therefore, in the mechanical equipment with large capacity and high torque requirements, this motor is usually used to drag.
