Document Type and Number:
Japanese Patent JP6285623
Kind Code:
B2
Abstract:
There is provided a hybrid stepping motor including a rotor including a plurality of rotor small teeth arranged at an equal pitch on an outer circumferential surface thereof, and a stator including a plurality of salient poles, each including a plurality of stator small teeth arranged to face the outer circumferential surface of the rotor via a gap. The stator small teeth have a predetermined stator tooth thickness and are arranged at a predetermined stator tooth pitch. The rotor small teeth have a predetermined rotor tooth thickness and are arranged at a predetermined rotor tooth pitch. A repulsion area ratio which is a ratio of an area of repulsion poles to a total area of all stator small teeth facing the rotor ranges from 0% to a predetermined threshold value.
