What is a liquid resistance starter?where it is used??.. Answer / anurag pattanayak Since in a Slip Ring Induction Motor, the Rotor resistance is low, this can cause very high current and low starting torque.SO by externally adding resistance, we increase the rotor resistance and thus decrease the starting current and increase the starting ...

A Slip Ring induction motor can be started with external resistance added in its rotor circuit. But how does external resistance aid in better starting characteristics? Read here to know about the starting arrangement and the role played by the external resistances in obtaining better starting characteristics. Also know about the qualities of slip ring induction motors.
