    摘要: A stator provided with annular split stator cores, formed by stacking steel plates. Each plate includes a yoke and a stator tooth. The cores include a yoke portion a stator tooth portion. The stator is manufactured by arranging an electromagnetic steel plate between a first die and a second die. The first die has a hole shaped as a steel plate. The second die has a projection inserted into the hole and shaped as a steel plate. The steel plates are formed by the first and the second dies. In a gap between an inner surface of the first die that defines the hole and an outer surface of the projection, a gap at a part that forms the stator tooth portion is larger than a gap at a part that defines a circumferential end surface of the yoke portion located in a circumferential direction of the stator core.

    摘要: A stator provided with an annular stator core formed by annularly arranging split stator cores, and also with coils mounted to the stator core. The split stator cores each includes a yoke portion extending in a circumferential direction of the stator core and a stator tooth protruding from the yoke portion. On at least part of side surfaces of the stator tooth that are arranged in a circumferential direction of the stator core, a radial end surface of the stator tooth that is located radially inward of the stator core, and, of radial end surfaces of the yoke portion that are arranged in a radial direction of the stator core, the radial end surface at which the stator tooth is formed, a rough surface portion is formed having surface roughness greater than that of circumferential end surfaces of the yoke portion that are located in a circumferential direction of the stator core.

    摘要: A drive device of a vehicle includes a motor generator, a lubricant circulating mechanism lubricating and cooling the motor generator, a power control unit controlling the motor generator, arranged on a circulation path of a lubricating oil and being in contact with the lubricating oil for transferring and receiving a heat to and from the lubricating oil, and a casing accommodating the motor generator, the lubricating mechanism and the power control mechanism, and provided with the circulation path. Preferably, the power control unit includes a power control element and a board (120) having a first main surface on which the power control element is mounted. The board (120) is provided on its second main surface side with a radiator fin (390, 392 and 394) for contact with the lubricating oil in the circulation path.
