Claim 10:
11. A variable reluctance motor assembly comprising:
a casing having a monocoque structure, a stator mounted within the monocoque structure, a rotor mounted within the monocoque structure and interfaced with the stator;
a sensor track connected to the rotor; and
a giant magneto resistive sensor mounted to the casing, where the casing includes a common datum that forms a stator interface surface configured to support the stator and position the stator and rotor relative to each other for effecting a predetermined gap between the stator and rotor and configured to support the giant magneto resistive sensor in a predetermined position relative to the common datum so as to effect a predetermined gap between the giant magneto resistive sensor and sensor track, where the stator, rotor, giant magneto resistive sensor and sensor track are positioned relative to and depend from the common datum.
