Claims

[Scope of utility model registration request]

Each phase pole of the stator core is formed by a plurality of divided poles that are excited at the same time, and the width of the portion of the plurality of divided poles that make up each phase pole, around which the phase winding that is simultaneously excited is wound, is determined in the rotation direction. A brushless motor characterized by an extremely thick split located on the side.
