摘要： There is provided a permanent magnet motor capable of reducing cogging torque and torque ripple while suppressing a decrease in motor output. In a permanent magnet motor 1 including a rotor 3 in which a plurality of permanent magnets 5 are arranged in a ring shape as a magnetic field unit, the transverse cross section of the permanent magnet 5 has an inside periphery 51 formed by a first arc 511 having the center of curvature O1 and the radius of curvature R1, and an outside periphery 52 formed by a second arc 521 having the center of curvature O2 and the radius of curvature R2, a third arc 522 having the center of curvature O3 and the radius of curvature R3 and joined to one end of the second arc 521, and a fourth arc 523 having the center of curvature O4 and the radius of curvature R4 and joined to the other end of the second arc 521. The above-described centers of curvature are disposed at different positions.

摘要： There is provided an electronic motor in which a stator core is thinned to obtain an increased diameter of a rotor is to produce a high power output, and a stator can be positioned with high accuracy at the time when a coil is wound on the stator. The outside peripheral surface of a yoke part 31 is substantially the same as the outside peripheral surface of a flange 42 of an insulator 4, and in a part of the flange 42, a cut-away part 43 is provided to expose a part of the end face of a stator core 30.
摘要翻译：提供了一种电子电动机，其中定子铁心被减薄以获得增加的转子直径以产生高功率输出，并且在线圈缠绕在定子上时可以以高精度定位定子。轭部31的外周面与绝缘体4的凸缘42的外周面基本相同，在法兰42的一部分中设置有切除部43，露出一部分定子芯30的端面。
