Abstract
A stator of an electric motor includes a stator core having a plurality of teeth. A printed circuit board (PCB) is fixed with respect to the stator and includes a plurality of soldering structures defined within a surface of the printed circuit board. A winding set is disposed on the teeth. The winding set includes at least one wire that is wound around the teeth to at least partially define stator poles. Each wire of the winding set includes opposing ends that are attached to the printed circuit board at a dedicated soldering structure of the plurality of soldering structures.
