Two phase motor fed from single phase supply, using control circuit

الملخص EN

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 are determined.

This
calculation is carried out, using the time phase angle as parameter.

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