Abstract

The paper discusses the synchronous modulation model of the SPWM frequency converter three-phase cage induction motor´s variable frequency speed regulation system at the carrier ratio of N=27. The fundamental frequency and mechanical characteristic parameters are calculated according to the parameters of the T801-4 motor. The result obtained show that its microcomputer control system is simple, the mechanical characteristic is robust and the motor was running steadily at low speed as the result of a high performance variable frequency and speed regulation
