Abstract

PURPOSE:To reduce the ripple propulsion by notching the teeth at both ends of an armature core 1 or the second teeth from the ends partially. CONSTITUTION:The teeth 1B at both ends of an armature core 1 are formed to have a 1/2 length of the width l of the core 1. The core 1 is formed of a single shaped silicon steel plate by laminating only l/2 by using the silicon steel plate with a shape that a single-sided end is only notched and laminating after that by placing a notch section on an opposite side. Accordingly, the detent propulsion (ripple propulsion) in case of using the teeth 1B is reduced to the same phase and to 1/2 amplitude in comparison with the time in case the notched teeth are not adopted, and the detent propulsion generated by each of the second teeth 1C from the ends is a waveform having a 1/2 amplitude with a slipped phase. Accordingly, the detent propulsion caused by the armature core 1 is reduced to 1/2 amplitude.
