2 The analysis of a Two-Phase Two-Poles Induction Machines carry out some assumptions such as, The stator windings are assumed to be sinusoidally distributed and connected to a balanced two-phase AC Source. The rotor windings are assumed to be sinusoidally distributed, and are short- circuited, as shown in the following figure.

The magnetic system rotates about the air gap mmf at ϖ e of the stator currents as a result of the rotating air gap mmf. Two rotating poles are established. A balanced 2 phase currents flowing in the stator windings of a 2 poles machine produce a constant amplitude rotating air gap mmf during the steady state operation. Two-Phase Two-Poles Induction
