摘要： In the prior art in which permanent magnets are regularly arranged over the whole circumference of a rotor core, a satisfactory magnetic flux distribution is hard to obtain, and the cogging torque and the distortion factor of the induced electromotive force waveform are large, whereby characteristics of a rotating electric machine are poor. Also, because the permanent magnets are arranged over the whole circumference, a large number of permanent magnets are required and cost reduction is difficult.A permanent magnet rotating electric-machine of the invention comprises a stator provided with a plurality of windings, and a rotor in which magnets are disposed in slots formed in a rotor core along an outer circumference thereof, the rotor core being fixed on a rotary shaft rotating inside the stator, and in which one magnetic pole is constituted by each group of three or more of the magnets. A total angle occupied by the group of magnets constituting one magnetic pole is in the range of 150 to 165 degrees in terms of an electrical angle.
摘要翻译：在现有技术中，永磁体规则地布置在转子芯的整个圆周上，难以获得令人满意的磁通分布，并且感应电动势波形的齿槽转矩和失真因数大，旋转电机差。此外，由于永久磁铁布置在整个圆周上，因此需要大量的永磁体，并且难以降低成本。本发明的永久磁铁旋转电机包括具有多个绕组的定子和沿其外圆周形成在转子铁芯中的槽中的磁体，转子芯固定在旋转轴上在定子内旋转，其中一个磁极由三组或更多磁体组成。构成一个磁极的磁体组占据的总角度在电角度为150〜165度的范围内。
