Document Type and Number:
Japanese Patent JP7052193
Kind Code:
B2
Abstract:
A stepping motor includes: a rotor; and a stator including an opening accommodating the rotor, a first side yoke extending from the opening in a first direction, a second side yoke extending from the opening in a second direction that is a direction opposite to the first direction, and one or a plurality of coils magnetically coupled to the first side yoke or the second side yoke. Assuming a direction orthogonal to the first direction and the second direction is defined as a third direction, a first recess is formed in an outer circumference of the stator at a position rotated from the third direction toward the second direction by a prescribed first angle and a second recess that determines a stable resting position of the rotor is formed at a position rotated from the second direction toward the third direction by a prescribed second angle.
