Abstract: A motor of an embodiment includes a rotor and a stator. The stator includes a plurality of segments. The segment includes a plurality of pieces coupled via a coupling part. The plurality of pieces are disposed in an arc shape. The plurality of segments are disposed in an annular shape. The coupling part includes a first recess part, a pair of opposing surfaces having first ends continuous with both sides of the first recess part, and a pair of opposing parts provided at second ends of the pair of opposing surfaces. A mutual gap between the pair of opposing surfaces decreases from the first recess part to the pair of opposing parts.

Abstract: A motor includes a rotor and a stator. The stator includes a plurality of segments coupled via engaging parts. The segment includes a plurality of pieces coupled via a coupling part. The plurality of pieces are disposed in an arc shape. The plurality of segments are disposed in an annular shape. The engaging part has two protruding parts projecting to a circumferential direction side and a recess part provided between the two protruding parts. Among the two segments disposed adjacently, the protruding part of one segment is engaged with the recess part of the other segment, and the recess part of the one segment is engaged with the protruding part of the other segment. The two protruding parts of the one segment and the other segment have top parts, and the protruding part of the one segment and the recess part of the other segment have a first plane and a third plane opposing one another.
