STATOR AND STATOR MANUFACTURING METHOD

摘要

A stator includes a stator core and an insulator. The insulator includes a main body and a wall. An adhesive is attached to a portion of a triangular gap between the wall of the insulator and a yoke of the stator core. The adhesive is expandable, and adheres and fixes the insulator to the stator core by expanding to fill in the gap by being heated. Also, a stator manufacturing method includes attaching an adhesive to the wall of the insulator or an inside wall of the yoke, installing the insulator on a tooth, and heating the stator core and the insulator.

主权项

1. A stator comprising:
a stator core including:
a yoke that extends in a circumferential direction; andteeth that protrude from the yoke in a radial direction, a slot being defined between the teeth which are adjacent to each other; an insulator that is assembled to each tooth from a tip end of the tooth,
the insulator including:
a main body within which the tooth is housed; anda wall that protrudes in a direction orthogonal to the radial direction from an end portion of the main body, a circumferentially end portion of the wall being configured to abut against an inside surface of the yoke in the slot; a coil that is wound around the main body of the insulator; and an adhesive that is attached only to a portion of a triangular gap between the yoke and the wall of the insulator, the adhesive being expandable, the adhesive being configured to adhere and fix the insulator to the stator core by expanding to fill in the triangular gap by being heated.
