Circuit Diagram Of Given Single Phase Induction Motor. To illustrate the simplicity of the ac induction motor. Now we assume that the rotor is rotating and it is placed in a magnetic field produced by the stator winding.
E m is the resultant induced voltage in the main winding. The no load current i 0 is simulated by a pure inductive reactor x 0 taking the magnetizing component i ยต and a noninductive resistor r 0 carrying the core loss. Single phase ac supply is given to the stator winding main winding.
So the net torque induced is zero at standstill.
The forward and the backward flux induces a voltage e mf and e mb respectively in the main stator winding. So the net torque induced is zero at standstill. The single phase induction motor circuit is given by double revolving field theory which states that a stationary pulsating magnetic field might be resolved into two rotating fields both having equal magnitude but opposite in direction. Ac motors single phase induction motors permanent split capacitor motor.
