摘要： In order to provide an electric rotating machine which is inexpensive and miniaturized while improving cooling performance of a rotor, a power supply unit is fixed on the axial side of a shaft in a bracket and a permanent magnet is arranged adjacent to the advancing side in the rotation direction of a claw-shaped magnetic pole portion of a magnetic pole on the side where the power supply unit is provided.

摘要： In an electric rotating machine which can improve rotating machine efficiency by suppressing a harmonic component of rotor magnetomotive force and reducing harmonic core loss, a permanent magnet is furnished in some of inter-magnetic pole portions, the inter-magnetic pole portion being formed between a first claw-shaped magnetic pole portion and a second such pole portion; the shapes of first and second chamfered portions provided in the inter-magnetic pole portion where the permanent magnet is inserted, differ from those of first and second chamfered portions provided in an inter-magnetic pole portion having no permanent magnet inserted; or the shapes of a first and second magnetic flux adjusting portions provided in the inter-magnetic pole portion where the permanent magnet is inserted, differ from those of first and second magnetic flux adjusting portions provided in the inter-magnetic pole portion where no permanent magnet is inserted.

摘要： With an object, of providing a rotating electric machine such that a reduction in size can be achieved, and a balance between a cooling performance and vibration resistance can be achieved, a multiple of connection portions formed of a first connection portion and a second connection portion that mechanically connect a rotating electric machine main body and a power converter are provided on a non-external device connection portion side bracket in the rotating electric machine main body and a heat dissipating member in the power converter, cross-sectional centers of the first connection portion and the second connection portion are caused to be positioned farther to an inner diameter side than an outer diameter of a stator, and a power module is disposed between two connection portions neighboring in a circumferential direction.

摘要： The rotating electric machine is configured in such a way that a surface of the heat sink, on which the cooling fins of the heat sink are formed, faces the housing; and a plate, which blocks the surface of the housing facing the heat sink and forms a wind passage between the heat sink and the plate, intervenes between the cooling fins and the surface of the housing facing the heat sink; and outside air is aspirated from an inlet formed on the protective cover, and then, the outside air is passed through the wind passage formed between the heat sink and the plate so as to be passed through a window formed on the housing, and is exhausted, by the cooling fan of the rotor, from an outlet formed on the housing.
