Rotating Electrical Machine Coil, Production Method of Rotating Electrical Machine Coil, and Rotating Electrical Machine

摘要

Provided is a rotating electrical machine coil in which an ununiform bulge of the rotating electrical machine coil protruded outside from the core is suppressed. A rotating electrical machine coil, provided by receiving the rotating electrical machine coil in a core of a rotating electrical machine and performing impregnation with insulating resin and curing of the insulating resin, includes: a plurality of coil conductors; and an insulating tape wound around the coil conductors a plurality of times to form an insulating layer, in which the insulating layer corresponding to at least a part of the coil conductors protruded from the core is provided so that a part of the wound insulating tape is adhered. A production method of a rotating electrical machine coil includes: a first winding step for forming an insulating layer by winding an insulating tape around a plurality of coil conductors at least once; and a second winding step for forming an insulating layer by winding the insulating tape around the insulating layer that has been formed in the first winding step and is a layer in which an adhesive member is applied or attached to at least a part protruded from the core.
