    • The wire 30 forming the stator winding 20 includes the in-slot portions 40 to be disposed in the slots 14 and 15 of the stator core 12 and the turned portions 42 connecting the in-slot portions 40 disposed in the circumferentially different slots 14 and 15. The turned portions 42 formed on axial opposite end sides of the stator core 12. The crank portion 44 which does not twist is formed at substantially the center of the turned portion 42. Steps are formed at sections of the turned portion 42 which protrude outside the stator core 12 from the slots 14 and 15. Further, the turned portion 42 of the wire 30 also has two steps 48 formed between the substantially central crank portion 44 and each of the steps 46 formed at the protruding sections of the turned portion 42.

    • A stator coil of a rotary electric machine includes a three-phase Y-form connection circuit including first windings Y1, Y2 and Y3, which are connected in Y-form, and a three-phase delta-form connection circuit including second windings .increment.x3, .increment.y3 and .increment.z3 which are connected in delta-form, wherein the second windings .increment.x3, .increment.y3 and .increment.z3 are sequentially inserted in slots of a stator core to have a phase difference of 120.degree. therebetween, and each of the first windings Y1, Y2 and Y3 is divided into two windings, and the divided first windings are separately inserted in the slots, in which the second windings .increment.x3, .increment.y3 and .increment.z3 have been inserted, so that the resultant composite voltage vector of each pair of the divided first windings is shifted by 30.degree. in phase from the voltage vector of one of the second windings .increment.x3, .increment.y3 and .increment.z3. By virtue of the foregoing structure of the rotary electric machinery, the number of slots decreases and an electromagnetic noise is reduced, since a magnetic force due to the air gap magnetomotive force distribution becomes substantially constant independently of a rotational position of a rotor.
    • 旋转电机的定子线圈包括三相Y型连接电路,其包括以Y形连接的第一绕组Y1,Y2和Y3以及包括第二绕组INCREMENT x3的三相三角形连接电路 ,以三角形形式连接的INCREMENT y3和INCREMENT z3,其中第二绕组INCREMENT x3,INCREMENT y3和INCREMENT z3依次插入定子铁芯的槽中,在其间具有120°的相位差,并且第一 绕组Y1,Y2和Y3被分成两个绕组,并且分开的第一绕组被分别插入插入第二绕组INCREMENT x3,INCREMENT y3和INCREMENT z3的槽中,使得所得到的复合电压矢量 一对分割的第一绕组从第二绕组INCREMENT x3,INCREMENT y3和INCREMENT z3之一的电压矢量的相位偏移30°。 由于旋转电机的上述结构,由于气隙磁动势分布引起的磁力与转子的旋转位置无关,所以槽的数量减少并且电磁噪声减小。
