When starting wound rotor motors, the operating lever is moved to the first running position to insert the full value of resistance in the secondary circuit. This allows the motor to start with reduced current and torque, which protects the motor and connected equipment from the high inrush current that would occur without the resistance. Once the motor is up to speed, the operating lever can be gradually moved to reduce the resistance and increase the motor's torque and speed.
