PURPOSE:To improve mechanical strength against the vibration of a winding end section, by forming a neutral point section with a ring astriding over the stator windings of respective phases. CONSTITUTION:U phase - W phase windings are organized with stator windings U1-U8, V1-V8, W1-W8 connected with interpole connecting wires 3. The U, V, and W phase winding ends are connected to a neutral point section 1 via leaders 2 respectively. The neutral point section 1a is formed with a ring 12 extended over the stator windings of U, V, and W phases respectively. The ring 12, the interpole crossover wires 3, and series wires 6 are bound with a binding wire 7 and are firmly integrated with one another. By this organization, even if vibration is applied to a stator winding 5 by an electromagnetic force or the like due to current on start, the vibration of the lead wires 5a, 5b of the winding start and winding end is suppressed.
