Abstract

In this paper a novel IPM motor rotor position extraction method using two reference-frames based on carrier frequency component signal, derived from PWM inverter switching, is presented. The method is utilized for IPM motor sensorless vector-control, extracting rotor position angle from switching carrier frequency (10 kHz) component current. The performance of two IPM motors´ sensorless control when this method is used have been investigated. Experimental results demonstrating good dynamic and steady state performance achieved are presented and discussed
