Assume that all of the timers are set for a time delay of 3 seconds. When the start button is pressed, motor #1 starts immediately. Three seconds later motor #2 starts, but motor #3 never starts. When the stop button is pressed, motor #2 stops operating immediately. After a delay of 3 seconds, motor #1 stops running. Which of the following could NOT cause this condition? a TR3 coil is open b 3M coil is open c TR2 coil is open d 2CR2 contact does not close

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.
