The use of the two-phase stator windings with phase-angle control leaving the 2-phase voltages equal in magnitudes, which leads to better utilization of the machine material. The operation of 2-phase motor from single phase supply carried out by connecting one stator phase directly to the voltages source, with exciting the second stator phase through the phase shifting element. Minimum calculation effort for the two-phase stator currents and the motor electromagnetic torque acting on the rotor

In this method, the starting and the maximum torque values can be controlled by changing the stator field from a pulsating of (0 o ) to a pure rotating field at (90 o ).
