    摘要： A permanent magnet type electric rotating machine comprises a stator having a salient-pole concentrated winding, and a rotor disposed with a rotational gap, and having a plurality of permanent magnets arranged and fixed in a circumferential direction inside, and an auxiliary salient pole provided between the permanent magnets. A ratio of the number of poles for the rotor and the number of slots for the stator is 2:3 and, when a slot pitch of the stator is &tgr;s (electrical angle), an angle &thgr; (electrical angle) made by a circumferential width of the permanent magnet in the surface of the stator side with an axis of the rotor is set at &thgr;≈n×&tgr;s/2+8×m (n=1 or 2, and m=1, 2 or 3). Thus, pulsation torque, cogging torque or the waveform distortion of a no-load induced voltage is selectively reduced as occasion demands.

    摘要： The invention provides a hybrid electric vehicle employing a permanent magnet type dynamo-electric machine structured such that a torque at a time of reverse rotation is greater than a maximum torque output by a dynamo-electric machine when the dynamo-electric machine normally rotates. Further, the present invention provides a hybrid electric vehicle in which a dynamo-electric machine and an engine are connected to a drive shaft in series and no gear for switching between forward and backward movements is provided, wherein there is employed a permanent magnet type dynamo-electric machine structured such that a torque output by the dynamo-electric machine when the hybrid electric vehicle moves backward (the dynamo-electric machine reverse rotates) is greater than a maximum torque output by the dynamo-electric machine when the hybrid electric vehicle moves forward (the dynamo-electric machine normally rotates). In the hybrid electric vehicle employing the permanent magnet type dynamo-electric machine having a stator having a stator iron core around which a stator coil is wound, and a rotor arranged in the stator at a rotational gap and having a plurality of permanent magnets arranged and fixed within a rotor iron core in a peripheral direction, a ratio between a maximum torque output by the dynamo-electric machine when the dynamo-electric machine normally rotates and a torque output by the dynamo-electric machine when reverse rotating establishes a relation 1:1.05-1.2, whereby the torque at the reverse rotation becomes greater.
