    • In a motor stator structure, a neutral-point bus ring is arranged along an inner peripheral portion of a stator, and alternately includes a larger-diameter portion, a first link portion, a smaller-diameter portion, and a second link portion. An end of a wound wire pulled out of a coil is located between radially-extending adjacent first and second link portions. A connecting terminal is connected at one end to the end of the wound wire, and at the other end to the first and second link portions. The use of the neutral-point bus ring ensures that a neutral point can be formed without bending the end of the wound wire of the coil into a U-shape. Particularly when a rectangular cross-section wire difficult to bend is used as the wound wire, the processing cost can be reduced.
    • 在电动机定子结构中,沿着定子的内周部布置有中性点母线环,并且交替地包括大直径部,第一连接部,小直径部和第二连杆部。 从线圈拉出的绕线的端部位于径向延伸的相邻的第一和第二连接部之间。 连接端子一端连接到绕线的端部,另一端连接到第一和第二连接部。 使用中性点总线环确保可以形成中性点而不将线圈的绕线的端部弯曲成U形。 特别是当使用难弯曲的矩形截面电线作为绕线时,可以降低加工成本。
