Abstract

Single-phase induction motors (SPIM) are widely used in household appliances, agriculture, trade, medicine and other areas where a cheap unregulated electric drive powered by a single-phase AC network is required. They are produced in millions of pieces per year. Therefore, significant attention has always been paid to research aimed at reducing resource consumption in the production and operation of these engines, improving the initial characteristics and increasing their competitiveness. The article conducted a study of the starting torque when starting single-phase induction motors depending on the initial phase of the voltage of the single-phase network supplying the stator winding, on the phase angles of the network voltage at fixed phase angles of the starting winding. It is also analysed how the active resistance and inductive leakage resistance of the stator winding and the equivalent rotor winding, and the resistance of the capacitor capacitance affect the starting characteristics of the engine.
