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： Provided is a control device for a motor generator, which enables suppression of a temperature rise of a motor generator. The control device includes a storage unit, a first acquisition unit, a second acquisition unit, and a control unit. The storage unit stores a plurality of control maps for controlling a motor generator. The first acquisition unit acquires first temperature information being information about a temperature of a power converter. The second acquisition unit acquires second temperature information being information about a temperature of a rotating electric machine. The control unit controls the power converter with reference to the plurality of control maps. Each of the control maps contains data including a field current command value. The control unit selects a control map to be referred to from the plurality of control maps based on the first temperature information and the second temperature information.

摘要： In a rotary electric machine, a first pole core body and a second pole core body are produced using solid cores, and first slits are formed on outer circumferential surfaces of a first boss portion and a second boss portion at a uniform pitch in a circumferential direction so as to have groove directions oriented in an axial direction to disrupt pathways of eddy currents that flow on the outer circumferential surfaces of the first boss portion and the second boss portion.
