Abstract
A stator of a brushless motor includes a stator core including a plurality of teeth arranged in a circumferential direction thereof, a slot being formed between any adjacent two teeth; and a plurality of phases of windings wound on the teeth and received in the corresponding slots. Each phase of winding includes two leading terminals, adjacent leading terminals of any adjacent two phases of windings extending out of the same slot, which simplifies the winding structure of the stator winding and reduces the short circuit risk between turns of coils of the winding. The windings can be formed by winding a single conductive wire uninterruptedly on the stator teeth. It is easily automated.
