Abstract
A stator includes a yoke extending in a circumferential direction about an axis line, a tooth extending from the yoke in a first direction toward the axis line, and a coil wound around and fixed to the tooth. The yoke has an inner wall surface facing the axis line. The tooth has a root part connected to the yoke. The inner wall surface of the yoke is a flat surface extending from an end of the root part of the tooth in the circumferential direction to an inner circumferential side relative to a plane passing through the end and perpendicular to the first direction.
Claims6
A winding method comprising the steps of:
- preparing a stator core having a yoke extending in a circumferential direction about an axis line and a tooth extending from the yoke in a first direction toward the axis line;
- and
- winding a plurality of layers of a coil around the tooth by repeating a step of winding one layer of the coil around the tooth and a step of securing the wound one layer of the coil,
- wherein in the step of securing the wound one layer of the coil, an adhesive agent is applied to the wound one layer of the coil and cured.
