Abstract

Loss analysis of small induction motors is conducted in order to show the differences by supplying with sinusoidal and PWM voltage. In the first part of the analysis, under sinusoidal voltage supply, the motor was tested according to the Canadian CSA C390-98 standard (based on IEEE 112B). These results are the reference for finite element-based and analytical loss calculations. In the second part of the analysis, the same procedure for determining the iron losses is carried out for the PWM voltage-fed induction motor. The obtained waveforms are comparatively studied, and an analytical approach is made to account for the increase of iron losses.
