Abstract

The invention provides a rotary motor capable of improving the cooling efficiency of a stator coil, a method for manufacturing the same, and a device possessing the same. Especially, a resin used for injection molding a stator iron core and the stator coil comprises a hole part reaching the exterior of the resin from the annular shaft direction end face of the stator iron core, the annular stator iron core is fixed in the interior of a frame possessed by the rotary motor, and the stator coil is arranged on the stator iron core. The hole part is arranged such that a plurality of parts from the peripheral part of the annular shaft direction end face of the stator iron core are opened outwards the resin separately, and are arranged as annular shaft directions of which the hole shaft directions are parallel with the stator iron core.

Description

technical field [0001] The present invention relates to a rotating electrical machine, a method of manufacturing the rotating electrical machine, and a device including the rotating electrical machine. Background technique [0002] Conventionally, there is a rotating electric machine in which a stator core is provided inside a frame. In such a rotating electric machine, the stator coil wound on the stator core and the stator core may be injected with resin (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 8-47218 [0004] In a rotating electrical machine, it is desirable to be able to efficiently dissipate heat generated from stator coils during operation. However, in the rotating electrical machine of Patent Document 1 in which the stator core and the stator coil are injection-molded with resin, no special measures are taken against the heat dissipation. Contents of the invention [0005] The disclosed tech...
