Abstract
A stator has a core, an insulating member covering the core, windings, wound around the insulating member, and conductive members, which supply drive power to the windings. The conductive members are inserted into insertion holes in the insulating member and are connected to coil ends. The insulating member is configured to be splittable such that a gap is formed at a split location. Auxiliary insulating means are provided at positions corresponding to the gap at at least one of the peripheries of the insertion holes and the conductive members.
Claims19
A stator, comprising:
- a core;
- an insulating member covering the core;
- a winding that is wound on the insulating member;
- and
- a conductive member for supplying drive power to the winding;
- wherein
- the insulating member is configured to be splittable at a split location;
