Answer» Single phase induction motor Single phase induction motor runs with single phase supply. The efficiency of the single phase induction motor is less than that of the three phase induction motor. Single phase induction motor are extensively used for domestic application like fans, coolers, geysers, mixies, washing machines etc. The rating of single phase induction motor is less than 1 KW or we can say that the single phase moter has fractional horsepower rating. The single phase induction motor looks like a three phase induction motor. It is constructionally same as three phase induction motor except that the starter has a single phase winding instead of 3 phase winding. Types of single phase induction motor (1) Split phase motor (2) Capacitor start motor (3) Shaded pole motor (4) Capacitor start capacitor run motor (5) Permanent split capacitor motor

Single phase induction motor

Single phase induction motor runs with single phase supply. The efficiency of the single phase induction motor is less than that of the three phase induction motor. Single phase induction motor are extensively used for domestic application like fans, coolers, geysers, mixies, washing machines etc. The rating of single phase induction motor is less than 1 KW or we can say that the single phase moter has fractional horsepower rating.

The single phase induction motor looks like a three phase induction motor. It is constructionally same as three phase induction motor except that the starter has a single phase winding instead of 3 phase winding.

Types of single phase induction motor

(1) Split phase motor

(2) Capacitor start motor

(3) Shaded pole motor

(4) Capacitor start capacitor run motor

(5) Permanent split capacitor motor
