レスモータ。[Claims for Utility Model Registration] A stator having a drive coil; a rotor having an annular drive magnet facing the drive coil inside a cup-shaped rotor plate and rotatably supported by the stator; , a pulse signal magnet formed on a part of the side wall of the rotor plate, and a pulse signal output coil disposed on the stator so as to be located near the side wall of the rotor plate. In this case, the pulse signal output coil has a main winding wound around a part of the winding groove of a bobbin having three or more winding grooves, and a winding with a smaller number of turns than the main winding on both sides of this winding groove. A brushless motor comprising auxiliary windings that are wound and connected in series on both sides of a main winding.
