Abstract
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.

A multipole motor assembly, comprising
- a housing;
- a stator assembly housed in said housing, comprising a plurality of stator electromagnets disposed circumferentially around an axis;
- a rotor assembly;
- and
- a cover assembly attached to an end of said housing, comprising an external electrical connector, a sensor, a flux carrier, a plurality of insulation displacement terminals and means for connecting said sensor and said plurality of insulation displacement terminals to said electrical connector;
- wherein said sensor is operable to measure a rotational position of the rotor assembly.
A method of assembling a multipole motor assembly, comprising:
- inserting a stator assembly, comprising a plurality of stator electromagnets disposed circumferentially around an axis, into a housing;
- inserting a rotor assembly into a stator assembly, such that a rotor shaft of the rotor assembly is coaxial with the stator assembly;
- and
- attaching a cover assembly with an external electrical connector to an end of said housing, such that the cover assembly holds the stator assembly and rotor assembly in the housing, and the plurality of stator electromagnets are electrically attached to the external electrical connector.
