Webb8 aug. 2024 · These resistors restrict the rotor current and boost the torque, reducing the starting stator current. Additionally, it helps in intensifying the power factor. The resistors are only employed during the start of the motor. It is removed as the motor picks up its considered speed. Advantages of Rotor Resistance Starter Motor When an electric motor, AC or DC, is first energized, the rotor is not moving, and a current equivalent to the stalled current will flow, reducing as the motor picks up speed and develops a back EMF to oppose the supply. AC induction motors behave as transformers with a shorted secondary until the rotor begins to move, while brushed motors present essentially the winding resistance.
