Refer to the circuit shown in Figure 49–16. Assume that the motor is running in the forward direction. When the REVERSE push button is pressed, the motor continues to run in the forward direction. Which of the following could cause this problem? a. The normally open side of the REVERSE push button is not making a complete circuit when pressed. b. R contactor coil is open. c. The normally closed side of the REVERSE push button is not breaking the circuit when the REVERSE push button is pressed. d. There is nothing wrong with the circuit. The STOP push button must be pressed before the motor will stop running in the forward direction and permit the motor to be reverse.

Single Phase Induction Motor

The single-phase induction motor or engine consists of a single rotating phase in the stator and a rotating cage in the rotor. When phase one supply is connected to the stator winding, a magnetic field is generated. In the pulsating field, the rotor does not rotate due to inertia. So, a single-phase import motor does not start and requires some initial methods.
