One of the methods used in a.c. motors for preventing undesirable pulsations of the reluctance is to skew the slots relative to the pole faces. In the case of variable reluctance motors, the torque ripple is the major factor which produces vibrations and noisy operation. Sometimes the magnitude of these vibrations can be large enough to cause bending of the rotor shaft. Therefore, the magnitude of the torque ripple should be reduced in order to minimize vibration. In this study, the author investigates the effect of skew as one remedy for the torque ripple problem, provides analysis for skewing the rotor, and highlights the effect of skew on the magnitude of the torque ripple and the average torque of a fractional horse power VRM.
