9.1 Introduction to Single-Phase Induction Motors

Single-phase induction motors are widely used in electrical appliances and gadgets like ceiling fans, exhaust fans, refrigerators, washing machines, etc. They require only single-phase supply to the stator. The rotor is squirrel-cage type and does not require any supply from a separate source.

9.2 Constructional Details

The constructional details of single-phase induction motors are more or less the same as that of three-phase induction ...
