Classification: CPC H | IPC H

Claim 4:
5. A variable reluctance motor casing comprising:
an exterior surface;
an interior surface where the exterior and interior surfaces form a drum structure, the interior surface including a common datum that forms a stator interface surface configured to support a stator and position the stator and a rotor relative to each within the casing to effect a predetermined gap between the stator and rotor; and
a sensor interface surface configured to support a giant magneto resistive sensor relative to a sensor track connected to the rotor and effect a predetermined gap between the giant magneto resistive sensor and sensor track, where the sensor interface surface is positioned relative to the common datum so that the stator, rotor and giant magneto resistive sensor are positioned from and supported by the common datum.
