The induction motor is classified into a single-phase motor and a three-phase motor according to the using power source. This motor always uses both auxiliary winding and condenser not only when starting but also during operation. Generally speaking, its starting torque is not so great, but its structure is simple and reliable. In addition, its connection is simple. It is suitable to use in houses and on factories. For a single-phase induction motor, be sure that the condenser indicated in the name plate should comply with the capacity of the motor.

For a single-phase induction motor, it is not possible to reverse the direction of rotation within a short time during operation because of the inertia torque exerting adversely against the direction the motor is supposed to change to.Thus, stop the motor first and change the rotational direction next. In case you do not, the motor can be damaged.

The power source of a single-phase motor includes J ( 100V 50/ 60Hz) , U( 115V 60Hz) , L( 200V 50/ 60Hz) C( 220V 60Hz, 230V 50/ 60Hz) . Refer to ( Fig. 1)
