    摘要： An object is to provide a rotating electric machine offering a high output and high efficiency by balancing inductance of each phase even if a stator is used in which stator windings of different phases are disposed in a slot of a stator core in a three-phase winding. A stator 5 includes a stator core 6 having a plurality of slots arrayed circumferentially and opening to an inner peripheral surface and a stator winding 7 wound in each of the slots. The stator winding 7 is divided into at least two for each phase (7U-A, 7U-B, 7V-A, 7V-B, 7W-A, 7W-B). After insertion of the stator core 6, the stator winding of each phase is connected in parallel or in series. The stator winding of each phase is disposed in slots such that combined inductance of different phases is equalized.

    摘要： An electrical rotating machine which includes: a rotor; a stator provided with an armature winding, the rotor and the stator being housed in a housing space formed by a front bracket and a rear bracket; and a rear cover provided with a circumferential side wall and a bottom wall and disposed near the bottom of the rear bracket. The rear cover includes a plurality of engaging openings formed in the circumferential side wall of the rear cover, and steps of the engaging openings each produced by the difference between the diameter of the side wall on the bottom wall side and the diameter of the side wall on the end opening side. The bracket has engaging portions inserted into the corresponding steps for fixing the rear bracket.

    摘要： It is an object of the present invention to make it possible to easily wind a stator winding, enhance an occupied ratio in a stator core, reduce a winding resistance because there is no coil end, and change a field magnetic flux in accordance with a use.Stator pawl magnetic poles of a stator core extend from both sides in an axial direction alternately at locations opposed to a rotor to form a plurality of magnetic poles. With this stator core, it is only necessary to annularly wind a stator winding. Therefore, it is possible to enhance operability and an occupied ratio, and since there is no coil end, it is possible to reduce winding resistance. Since the rotor is a Randall type rotor having a field winding and a rotor pawl magnetic pole, it is possible to change the field magnetic flux in accordance with a use.

    摘要翻译： 本发明的目的是使得可以容易地缠绕定子绕组，提高定子铁芯的占有率，由于不存在线圈端而降低绕组电阻，并且根据使用改变励磁磁通量 。 定子铁芯的定子爪磁极在与转子相对的位置处沿轴向方向两侧交替地形成多个磁极。 利用该定子铁心，只需要环绕定子绕组。 因此，可以提高可操作性和占有率，并且由于不存在线圈端，因此可以降低绕组阻力。 由于转子是具有励磁绕组和转子棘爪磁极的兰德尔型转子，因此可以根据用途改变励磁磁通量。
