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.

Question

A three-phase switched reluctance motor has Ns = 6 stator poles, Nr 4 rotor
poles and two coils per phase on opposite stator poles with Np = 50 turns each.
A current of i = 10 A flows through the two coils in series. Assume that the
unaligned inductance Lu = 0 H, and the aligned inductance La = 0.011 H.
Calculate the electromagnetic torque and angle of rotation at which the torque
is essentially constant, if the current is constant.
(Maximum inductance (aligned position) at 24 and minimum inductance
(unaligned position) at 0" for each movement)
