    摘要： A permanent magnet rotating electric machine uses no skewing under a predetermined current and voltage condition to prevent torque from decreasing and to decrease pulsation torque to make the machine less vibrating and less noisy. The permanent magnet rotating electric machine includes a stator with multi-phase stator windings and a rotor with a plurality of permanent magnets internally embedded in a rotor core. The core shape of the rotor is uniform in the depth (longitudinal) direction with no skewing in the arrangement of the permanent magnets. The permanent magnets are symmetrical with respect to the rotation direction, but irregular with respect to the depth direction, for each pole. A magnetic flux generated from the between-pole permanent magnets almost equals a magnetic flux generated from the pole-center permanent magnet.

    摘要翻译： 永磁旋转电机在预定的电流和电压条件下不会发生偏斜，以防止转矩降低并且降低脉动转矩，使机器振动较小，噪音较小。 永磁旋转电机包括具有多相定子绕组的定子和具有内部嵌入转子芯中的多个永磁体的转子。 转子的核心形状在深度（纵向）方向上是均匀的，而在永久磁铁的布置中没有偏斜。 对于每个极，永磁体相对于旋转方向是对称的，但是相对于深度方向是不规则的。 从极间永磁体产生的磁通几乎等于从极中心永磁体产生的磁通量。

    摘要： A sintered magnet and a rotating machine equipped therewith are disclosed, which include: crystal grains of a ferromagnetic material consisting mainly of iron, and a fluoride compound or an oxyfluoride compound, containing at least one element selected from the group consisting of an alkali metal element, an alkaline earth metal element, and a rare earth element, the fluoride compound or the oxyfluoride compound being formed inside some of the crystal grains or in a part of a grain boundary part. The oxyfluoride compound or the fluoride compound contains carbon, and a grain boundary width of the ferromagnetic material is smaller than a grain boundary width of the ferromagnetic material in which the fluoride compound or the oxyfluoride compound is formed.
