What is it about?
Influence of magnetic saturation on the rotor bar current waveform and performance characteristics of a squirrel-cage IM is investigated. The levels of iron saturation in different parts, including stator and rotor back iron, tooth body and tooth tips etc., are examined and their influences are investigated, while the dominant part which causes the non-sinusoidal rotor bar current waveform is identified.

Why is it important?
Our findings show that the magnetic saturation, particularly in the rotor tooth, has a significant effect on the bar current waveform and the phenomenon is explained in depth.
