Motor

The invention provides a motor which increases the space factor of coils in slots. A stator core (10) has a circular ring-shaped yoke (12) and multiple teeth (14) protruding from the circular ring-shaped yoke (12) toward the inner peripheral side of the radial direction. The multiple slots are formed among the multiple teeth (14). Multiple track-shaped coils (30) are respectively provided with windings which are regularly arrayed and wound. In the distributed winding manner that the multiple track-shaped coils (30) are respectively inserted into slots in one side of the outer peripheral side and one side of the inner peripheral side, the multiple slots are accommodated by maintaining regular arrangement of the windings. 本发明提供种提高狭槽内的线圈的占空系数的马达。定子芯(10)具有圆环状轭(12)及从圆环状轭(12)向径向内周侧凸起的多个齿(14)，在多个齿(14)之间形成有多个狭槽。多个跑道型线圈(30)各自具有有规则地排列而卷绕的绕组。多个跑道型线圈(30)分别以插入于外周侧的1边与内周侧的1边不同的狭槽的分布绕组的方式，在维持绕组的规则排列的状态下容纳于多个狭槽。
