Multi-pole electromagnetic motor apparatus and method of assembling

摘要

A structure and methodology of fabrication for a cost effective multipole motor adapted to high volume manufacture. The apparatus includes a low cost housing within which a stator assembly comprised of interchangeable stator electromagnets is installed. A rotor assembly including a plurality of sense magnets and motor magnets integrated onto a rotor shaft is also used. A cover assembly is attached to complete the device. The cover assembly includes a lead frame interconnection assembly and a magnetic sensor adapted to detect the passing of sense magnets to determine the position of the rotor shaft.
