SOLUTION

In a repulsion motor, the torque developed is proportional to the square of the stator current, the torque-speed characteristics of a repulsion motor are high. The magnitude of starting torque of a repulsion motor is high. The magnitude of starting torque depends on the position of the brush axis. Its speed regulation, like a series motor, is poor.  The found application in Air compressors, lifts, and hoists, Mining industries, Pumps and fans, Electric trains, etc.
