    摘要: In an electric power unit which accommodates at least an electric motor in a housing, polygonal rib regions in which polygonal ribs are respectively formed are provided on at least two surfaces of an outer peripheral surface of the housing, and the polygonal rib regions are connected by a circumferential rib. Here, a first axial rib and a second axial rib extending parallel to an axial direction are formed on the outer peripheral surface of the housing, and the polygonal rib region is provided in a portion sandwiched between the first axial rib and the second axial rib. Further, the circumferential rib is formed over the entire part of the polygonal rib region in a circumferential direction. Note that the polygonal rib is a honeycomb rib.

    摘要: A one-piece generator housing locates and secures the generator stator assembly, rotor bearings, and brush holder, and provides for attachment of the housing assembly to the engine interface. The disclosed one-piece housing completely encloses the stator and rotor assembly of the generator. An embodiment of the one-piece generator housing is applied to welding machine applications that use an in-line engine. With this type of engine, the power take-off (PTO) is normally the engine flywheel, and the variety of engine interfaces to which to mount the generator become more diverse. In an embodiment, the rotor has a flange with integral cooling fan blades that bolts to the flywheel. A shorter adapter is used in order to access the fasteners that attach the rotor shaft to the flywheel. The housing attaches to the adapter using cast-in bosses and bolts.

    摘要: The disclosure provides a motor and a motor assembling method. The motor includes a housing having a bottom and a wall portion extending from an edge of the bottom along an axial direction, and a lid connected to the housing on one side in the axial direction of the bottom of the housing. A surface on the one side in the axial direction of the bottom of the housing has a first connection surface. Housing portions on an inside and an outside in a radial direction of the first connection surface are respectively bent in opposite directions intersecting the first connection surface, which ensures sufficient working space when performing work for connecting the housing and the lid.

    摘要: An electric compressor includes a compression part, an electric motor, an inverter device, and a housing. The inverter device includes an inverter circuit, a noise reduction unit, and a circuit board. The noise reduction unit includes a common mode choke coil and a smoothing capacitor. The common mode choke coil includes an annular core, a pair of winding wires, and an annular electrical conductor. The electrical conductor is split into a first metal plate and a second metal plate in a circumferential direction. The first metal plate is thermally coupled to the housing. The second metal plate is electrically connected to the first metal plate. An electrical resistance value of the first metal plate is larger than that of the second metal plate.
