There is provided a hybrid stepping motor including a rotor including a plurality of rotor small teeth arranged on an outer circumferential surface thereof, and a stator including a plurality of salient poles, each including a plurality of stator small teeth. 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, and a facing area which is a difference between an area of attraction poles of the stator small teeth and the rotor small teeth and an area of repulsion poles thereof ranges between a maximum value in a parameter space of a dimensional ratio of the stator and/or the rotor and a threshold value of the maximum value. |
