Abstract
Disclosed is a stepping motor including: a rotor magnetized in a radial direction; a stator having a straight section extending in a first direction, an overhanging section provided on at least one end side of the straight section and overhanging in a direction intersecting an extending direction of the straight section, and a rotor receptacle provided in the overhanging section to receive the rotor; two yokes located along a longitudinal direction of the straight section on both sides of the straight section respectively; and a plurality of coils magnetically coupled to the stator. The overhanging section has first notches provided at least on both sides across the rotor and second notches extending further toward an end side in the first direction of the stator than the first notches.

A stepping motor comprising:
- a rotor magnetized in a radial direction;
- a stator having a straight section extending in a first direction, an overhanging section provided on at least one end side of the straight section and overhanging in a direction intersecting an extending direction of the straight section, and a rotor receptacle provided in the overhanging section to receive the rotor;
- two yokes located along a longitudinal direction of the straight section on both sides of the straight section respectively;
- and
- a plurality of coils magnetically coupled to the stator, wherein
- the overhanging section has first notches provided at least on both sides across the rotor and second notches extending further toward an end side in the first direction of the stator than the first notches.
A timepiece comprising:
- a stepping motor comprising:
- a rotor magnetized in a radial direction;
- a stator having a straight section extending in a first direction, an overhanging section provided on at least one end side of the straight section and overhanging in a direction intersecting an extending direction of the straight section, and a rotor receptacle provided in the overhanging section to receive the rotor;
- two yokes located along a longitudinal direction of the straight section on both sides of the straight section respectively;
- and
- a plurality of coils magnetically coupled to the stator, wherein
- the overhanging section has first notches provided at least on both sides across the rotor and second notches extending further toward an end side in the first direction of the stator than the first notches;
- and
- a hand moved by the stepping motor.
