The influence of methods of modulation of the magnetic field on the working properties of two-speed asynchronous motors.

Abstract

A study was made of the influence of modulation methods of the magnetic field on the working properties of asynchronous short-circuits motors. Motor stator windings are formed in two ways: by pole-amplitude modulation and phase modulation. The electrical properties of various modulated windings are analyzed. Modulated windings have been shown to have improved technical and economic indicators compared with machines that have separate windings.
