Abstract :
Accurate measurement of power losses of high efficiency motors and converters is difficult and extra challenge is caused by pulse-width-modulated (PWM) signals. Soon, the converter-fed motors, converters, and power drive systems will get their own efficiency classifications. Also, the methods how the device losses shall be determined are given in corresponding standards. This paper presents 37 kW induction motor loss measurement results with sinusoidal and PWM supply. Five different commercial frequency converters are used to obtain single motor losses.
