More Information
Summary:The invention provides a stator and a motor. The stator includes an annular core-back portion, a plurality of teeth portions and a plurality of insulators. The teeth portions extend radially from a circumferential surface of the core-back portion. The insulators are respectively mounted to the teeth portions. The insulators include tube portions and leading lines. The cross section of the coils is round and forms coils. Slots are arranged between adjacent teeth portions. The number of slots is set as N, a is equal to 180 DEG divided by the number of the slots, d2 is an inner diameter of the core-back portion, TW is the width of the teeth portions in the direction perpendicular to the extension direction of the teeth portions, S is the leading line width, and Li is the width in the insulators of the portions included by the inner side of the core-back portion and the coils. The width TW of the teeth portion is shown by the following equation. An integer M is any one of 2, 3, and 4.
