The choice of the design expression of the specific magnetic conductivity of the air gap of an induction motor, taking into account the steel saturation.

Abstract

The possibility of obtaining the expression of the specific magnetic conductivity of the gap due to the saturation (UMPN) of an induction motor, providing acceptable results at different levels of saturation of individual sections of the magnetic circuit, is investigated. The expression of the EMT is obtained by factorial experiment planning based on the results of a numerical analysis of the magnetic field in the working area of ​​an induction motor using the finite element method. Taking into account the results of physical and numerical experiments, the choice of the most acceptable expression of the DMPS is justified.
