One of the causes of characteristic deterioration and generation of vibration in hybrid stepping motor is the harmonic component flux contained in the field flux. In this paper, a method is described for reducing harmonic components by using a rotor consisted of two sets of rotor which is commonly used in hybrid stepping motors of comparatively large output. A trial of reducing harmonic is made by using such a type of rotor whose two component rotors are arranged on a shaft to give some angular displace ment in order to get some phase shift between flux distribution of their magnets. Through the experiment on various sample motors, it was confirmed that this method is fairly effective in decreasing the harmo nic components to improve the characteistic of stepping motors both in full-step operation and microstep operation.
