Accounting for changes in the parameters of equivalent circuits of asynchronous electric motors with phase control.

Abstract

A mathematical model for calculating the performance of asynchronous motors under phase control is proposed. The harmonic components of non-sinusoidal voltage, supplying a number of conventional engines, with the help of which the real engine is presented, are considered. Parameters of equivalent circuits of conditional engines are located at each load and control point. Experimentally confirmed the correctness of the proposed mathematical model.
