Development of a mathematical model for a frequency-controlled asynchronous motor rotor temperature field on the basis of differential equations of heat conduction

Abstract

A mathematical model of the temperature field of a frequency-controlled asynchronous motor rotor is made out on the basis of differential equations of heat conduction. The model developed is approved in the course of experimental research on the motors examined.
