Working of Slip Ring Induction Motor

Slip Ring in Motors A stator winding generates magnetic flux when it is energised by an AC source. The rotor winding induces and produces a magnetic flux current according to Faraday's law of electromagnetic induction. The torque created by this generated EMF allows the rotor to spin.

Fabcouniversal is a carbon brush manufacturer in Delhi NCR. However, because the created torque is not unidirectional, the phase difference between the voltage and current does not match the requirements to generate strong beginning torque. To increase a motor's phase difference, a large external resistance is added to the circuit. Inductive reactance and the phase difference between I and V are thus decreased. This decrease enables the motor to provide strong starting torque as a result.
