摘要： In a motor having a pawl-shaped magnetic pole, if a coil is wound like a ring shape so as to be formed, one leader line can be generally drawn out to an external portion from a position close to an outer periphery of a stator, however, the other leader line is drawn out to the external portion from an inner periphery of the stator. Accordingly, the leader line occupies a part of the inner space formed by the stator core, so that there is generated a problem that a space factor of the coil is reduced. Accordingly, an object of the present invention is to improve the space factor of the coil. In order to achieve the object mentioned above, a space passing wirings of a plurality of coils therethrough is provided in a part of the pawl-shaped magnetic pole of the stator core of the stator having the pawl-shaped magnetic pole. Accordingly, one of leader lines of the coil is drawn out from an outer peripheral portion (or an opposite side to a side facing to the rotor) of the stator, and the other is drawn out in an axial direction from the space of the claw-shaped magnetic pole of the stator. Therefore, it is possible to do away with an influence by the leader line, it is possible to increase a winding number of the coil even in the same space, and it is possible to improve a downsizing of the motor.
摘要翻译：在具有棘爪状磁极的电动机中，如果线圈被卷绕成环状形成，则可以将一条引线一般从靠近定子外周的位置抽出到外部，然而，另一个引导线从定子的内周被拉出到外部。因此，引导线占据由定子铁芯形成的内部空间的一部分，从而产生线圈的空间系数减小的问题。因此，本发明的目的是提高线圈的空间系数。为了实现上述目的，在具有棘爪状磁极的定子的定子铁心的棘爪状磁极的一部分上设置有多个线圈的配线的空间。因此，线圈的引线之一从定子的外周部（或与转子相对的一侧的相反侧）拉出，另一方从爪的空间沿轴向拉出定子的磁极。因此，可以避免引线的影响，即使在相同的空间也可以增加线圈的绕组数，可以提高电动机的小型化。
