Abstract

An integrated stator assembly incorporated in an electric motor including a rotor that includes a plurality of rotor magnets, each rotor magnet of the plurality of magnets having a polar axis running from a rotor magnet south pole to a rotor magnet north pole. The assembly comprising a mandrel of dielectric material, wherein the mandrel includes a first cylindrical surface coaxial to an axis of rotation of the rotor, an upper edge, and a lower edge. A plurality of electrically conductive stator windings wound upon the mandrel, each winding of the plurality of windings including a plurality of turns traversing the first cylindrical surface, wherein each turn of the plurality turns further comprises a first upper section disposed on the first cylindrical surface, wherein the first upper section intersects the upper edge of the mandrel, and the first upper section forms a first angle to the axis of rotation.
