PURPOSE:To enhance the productivity by bending the coil ends of stator windings to avoid phase winding crossing of an end loop, and forming the winding shape of 1-pole 1-phase the same for all 1-pole 1-phases, thereby reducing the types of the coil shapes. CONSTITUTION:One coil end of a coil 5 of a stator winding is bent at an end loop 6 to be disposed at a lower position, and the other coil end is bent at the other end loop 6a to be disposed at a lower position. The end linear portion 7 of one side connected with the loop 6a is bent to be disposed lower than the loop 6a. Four types of pitches of the coils 5 are used to form 1-pole 1-phase of single layer coaxial winding of 3-stage configurations. made of U-, V- and W-phases. |
