  • Publication number: 20170126098
    Abstract: The present invention provides a rotating electric machine comprising: a stator; a rotor disposed in such a manner that the outer peripheral surface of the rotor faces the inner peripheral surface of the stator; and a plurality of coil supports that support between poles of a coil forming the rotor, wherein the coil supports are detachably configured with respect to the rotor, at least one of the coil supports is provided with a fin formed of a member different from that of the coil support, and the fin is provided in such a manner that a windway through which a swirl flow occurring with the rotation of the rotor passes is formed between the coil and the fin.

  • Patent number: 9077223
    Abstract: An electrical rotating machine is provided with a salient-pole rotor, which is composed of magnetic field pole bodies integrally formed with a shaft and pole shoes constituting magnetic field pole heads. Each pole shoe is fixedly joined on the corresponding one of the magnetic field pole bodies with a plurality of bolts. Each pole shoe or its corresponding magnetic field pole body is provided with at least one protrusion or recess for restricting a conically-shaped compression domain in a compression domain that occurs in the pole shoe when the pole shoe is joined on the corresponding magnetic field pole body with the bolts.

  • Publication number: 20050077788
    Abstract: In a collector device for supplying an electric power to a rotor of a motor with a cooling by a cooling medium, an annular collector electrode is fixed to the rotor to supply the electric power to the rotor through a cylindrical outer surface of the collector electrode, an electrically conductive brush is contactable with the cylindrical outer surface of the collector electrode to supply the electric power to the collector electrode, and a cooling medium outlet opens to at least partially face to the collector electrode in such a manner that the cooling medium is supplied from the outlet to the collector electrode in each of circumferential directions of the rotor opposed to each other circumferentially to be divided into two flow parts in respective circumferential directions of the rotor opposed to each other circumferentially.
