Effect of induction machine's load and rotor eccentricity on space harmonics in the air gap magnetic flux density

The paper discusses the air gap field distribution of an induction machine operating under special conditions. It focuses mainly on effects of machine's load and its rotor eccentricity on volume of space harmonics and their magnitudes. The study compares limited analytical prediction with full-scale FEA approach and gives a short overview of crucial aspects of machines' design.
