Effect of rotor iron pole radii and skew on performance of interior permanent magnet motors is studied in this paper. A comparison is carried out by finite element analysis method and is confirmed by the experimental results obtained with two laboratory prototypes. The results show that, although the skew method is very effective in suppressing the cogging torque of an interior permanent magnet (IPM) motor, it will deteriorate other performances more in respect to radii ratio method.
Author Keywords: Interior permanent magnet motor, pulsating torque minimization, rotor iron pole radii, skew ratio.

Abstract
Effect of rotor iron pole radii and skew on performance of interior permanent magnet motors is studied in this paper. A comparison is carried out by finite element analysis method and is confirmed by the experimental results obtained with two laboratory prototypes. The results show that, although the skew method is very effective in suppressing the cogging torque of an interior permanent magnet (IPM) motor, it will deteriorate other performances more in respect to radii ratio method.
