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).
تشغيل المحرک ثنائي الاوجه من مصدر احادي باستخدام دائره ازاحه زاويه استخدام دائره الکترونيه لإيجاد زاويه طور تتغير من90درجه الى30 درجه لتغير من شکل منحنيات العزم مع السرعه عند ثبوت الحمل.کما ان تشغيل المحرک بوجهين منتظمين يتم في حاله ثبوت الزاويه عند 90 درجه وهذا يساعد على رفع قيمه العزم البدء وکذلک العزم الاقصى للمحرک. هذه الطريقه تجعل من الممکن تطبيقها في المحرکات احاديه الوجه حتى تتخلص من حاجتها الى مکثف بدء تشغيل ومفتاح طرد مرکزي ويقلل من أعطال المحرک0
