に嵌めたことを特徴とする小型電動機。 A stator core is formed by arranging a yoke for winding a single stator winding and an opening into which a rotor is inserted, and has magnets whose surfaces are magnetized to different polarities, and rotates around a rotating shaft. A small electric motor that has a rotating rotor and a control unit that magnetically detects the rotational position of the rotor in an aperture and switches the current direction of the stator winding, which has a bearing that supports the rotating shaft and is fixed. A bracket fixed to the child core, a bobbin provided on the yoke around which the stator winding is wound, and an engagement hole that fits into the protrusion of the bobbin, and located between the stator core and the bracket. It includes a control section that is attached to this board and molded with a resin material, and a heat sink that radiates heat from the control section. A small electric motor characterized by having its end fitted into a groove in a stator core.
