Abstract
A motor has a rotor rotatable about an axis, a can surrounding the rotor and having an outer surface, and a plurality of outwardly projecting stator supports fixed on the outer surface, and respective stator windings mounted directly on the stator supports. The stator supports project radially of the axis and there are at least three and at most twelve such stator supports and they are angularly equispaced about the axis.
