The effects of magnetic saturation on the radial magnetic force in induction machines when the rotor is performing cylindrical circular whirling motion are studied in this paper. Impulse method in the finite element analysis is used to calculate the forces and the eccentricity harmonics from both, the air gap flux density and rotor currents. The forces are studied as a function of supply voltage in order to find out the effects of the saturation on them. The maximum radial force is found to bedoi:10.1109/tmag.2004.824549 fatcat:brnnqw24jvgbrbkbpuhktm74tm
