Abstract
A brushless motor that can uniformly wind a coil winding at a low cost even with a stator core in which intervals between tooth tips of a plurality of pole teeth provided in a circumferential direction of an annular section to protrude in a radial direction differ. An auxiliary tooth tip section is formed integrally on a tooth tip of a required pole tooth of a stator core in which a plurality of pole teeth are provided in a circumferential direction of an annular section to protrude in a radial direction, and in which circumferential intervals between adjacent tooth tips are not uniform, and gaps between the tooth tips of all the pole teeth of the stator core are formed uniform.
