Rezumat
Cuprinsul lucrarii se refera procedeul de pornire a engineului monofazat fara infasurare auxiliara de
pornire sau fara elemente de defazaj cunoscute si folosite in practica. Sunt prezentate particularitatile constructive
ale engineului. Fiind luate in consifderatie procesele fizice corespunzatoare constructiei deosebite, acestea au fost
descrise matematic. Analiza matematica a permis de a determina tensiunile electromotoare induse in infasurari,
fortele magnetizante si cuplul electromagnetic aplicat la arbore la pornirea engineului monofazat.

Abstract
The paper refers to the process of starting the single-phase engine without auxiliary starting winding or
phase shift elements known and used in practice. Constructive particularities of the engine are presented in the
work. Physical processes appropriate to the special construction had been considered and described mathematically.
The mathematical analysis allowed determining the induced electromotive voltages in windings, the magnetizing
forces and the electromagnetic torque applied to the shaft at single-phase engine start.
