    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 rotating electric machine that can be improved in cooling performance is provided. An end plate includes an annular plate portion arranged to be spaced from a rotor in an axial direction and secured to a rotation shaft, and a tubular portion protruding from an outer edge of the annular plate portion to abut on an axial end surface of the rotor. A partition plate arranged between the rotor and an end plate forms a first space between the rotor and the partition plate and a second space between the annular plate portion and the partition plate. A communication passage allowing the first space and the second space to communicate with each other is formed in the partition plate at a radially outer side relative to a permanent magnet. A through hole extending through the annular plate portion in the axial direction is formed in the annular plate portion at a radially inner side relative to the permanent magnet.
