タ。 a rotor provided with a back yoke having a smaller diameter than the outer diameter of the drive magnet that faces an annular drive magnet fixed to a rotating shaft with a gap in the axial direction and rotates together with the drive magnet;
The stator is composed of an insulating member that holds a plurality of windings arranged with a certain gap between the drive magnet and the back yoke, and the stator has a rotating shaft passing through the center thereof, and supports the stator. A flat brushless motor is constructed of a pan-shaped fixed yoke that has a flange on its inner diameter that is larger than the outer diameter of the back yoke and smaller than the outer diameter of the drive magnet.
