MOTOR AND METHOD OF MOLDING RESIN CASING

摘要

The insulator of the motor has an inner wall part in the diameter direction of a coil. The inner end of the diameter direction of a tee is higher than the inner surface of the diameter direction of the wall part. A resin casing has an inner resin part of ring shape located in a diameter direction compared to the wall part. The inner resin part has convex parts on one side in an axial direction compared to at least tee and concave parts adjacent to the convex part. And, the convex parts are overlapped with each wall part in the diameter direction. Like this, the thickness of the diameter direction of the resin is increased in the inner diameter direction of the wall part. As a result, the delamination of the resin after molding can be prevented.
