Analysis of losses and thermal state of an induction motor when powered by an autonomous current inverter

Abstract

The mathematical model of drive with current source frequency converter fed induc tion motor for steady-stage modes of motors operate with the taking into account high time harmonics and change of motor parameters in a regulation is offered.The results of caicu- ations of the motor 's losses and temperature of stator winding of cage induction motor 4A250S4 are given
