Electric motor with integrated printed circuit board coils

Abstract

An electric motor assembly including a printed circuit board including a plurality of apertures, wherein at least three apertures of the plurality of apertures are enclosed by coils, the coils being integrated in the printed circuit board, a stator including a ring portion and a plurality of teeth extending axially from the ring portion, the plurality of teeth extending through the plurality of apertures, and a rotor arranged adjacent the plurality of teeth, the rotor including a first ring magnet, wherein the coils are arranged to generate a magnetic flux within the stator that is transferred to the rotor to generate circumferential displacement in the rotor about an axis of rotation, and the plurality of teeth extend in an axial direction arranged parallel to the axis of rotation.
