ROTATING ELECTRICAL MACHINE AND METHOD FOR MANUFACTURING ROTATING ELECTRICAL MACHINE

摘要

A rotating electrical machine includes a rotor and a stator positioned circumferentially around the rotor. The stator includes multiple core elements arrayed in a circumferential direction of the rotor such that the core elements form multiple slots arrayed in the circumferential direction, and a unitary cylindrical coil resin structure including molded resin and lap wound air-core coils resin-molded in the molded resin, each of the air-core coils having an air-core, a first side portion and a second side portion extending on the opposite sides of the air-core such that the first side portion extends through a first one of the slots and the second side portion extends through a second one of the slots.
