Concept explainers

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.

If the shunt field is disconnected and is connected to a rheostat to control the speed of the dc machine, what should be the case if it is desired to increase the speed of the motor? -The resistance of the field rheostat should be decreased to be able to increase the speed of the motor -The resistance of the field rheostat should be increased to be able to increase the speed of the motor -The resistance of the field rheostat should not be changed to be able to increase the speed of the motor -The terminals of the field rheostat should be short circuited to be able to increase the speed of the motor b.
