Induction Motor Working Principle your electrical guide

Jul 08, 2017The figure shows the simple circuit diagram of a slip ring induction motor. The stator can be either delta-connected or star-connected. The rotor is always star connected and any resistance can be inserted in the rotor circuit as shown in the figure. The external resistance is usually known as starting resistance because it is generally inserted in rotor circuit at the start to limit the heavy

Induction motor startup and losses calculation EEP

Induction motor startup and losses calculation If the rotor resistance is increased by some means, then the slip and speed at which maximum torque occurs can be shifted. For that purpose, external resistance can be introduced in the rotor circuit, which is done in the case of slip ring or wound rotor type motors.
