Development of Equivalent Circuit in Single Phase Induction Motor (Contd.) — Lesson 11

This lesson covers the intricate workings of a single phase induction motor. It delves into the structure of the motor, explaining the role of the cage rotor and the single phase winding. The lesson further discusses the concept of a pulsating field produced by a single phase current and how it affects the operation of the motor. It also explains why the motor doesn't run initially and how an external rotation can help it speed up. The lesson then moves on to the analysis of the motor, introducing the concept of an assumed coil carrying no current. It concludes with a detailed explanation of how to calculate the torque developed by the motor.
