Redundant variable reluctance resolver |
摘要 |
A multiplex resolver includes m resolver units disposed in tandem each comprising a rotor and a stator, where m is an integer not less than 2. The stator has a stator yoke, a plurality of stator magnetic poles projecting from the yoke, and excitation and output windings applied to the stator magnetic poles. The number of the stator magnetic poles corresponds to a shaft angle multiplier nX (n is an integer not less than 1) of the resolver. The rotor has n salient poles in accordance with the shaft angle multiplier nX. The respective stators of the resolver units are connected together such that the stator magnetic poles of the stator of one resolver unit do not overlap the stator magnetic poles of the stator of another resolver unit, as viewed in the axial direction. <IMAGE> |
