First Claim
Patent Images
1. A double variable reluctance resolver comprising:
- a first VR resolver, wherein the first VR resolver includes a first plurality of stator magnetic poles and a first rotor;
a second VR resolver, wherein the second VR resolver includes a second plurality of stator magnetic poles and a second rotor, wherein a predetermined group of the poles of the second plurality of stator magnetic poles correspond to the first plurality of stator magnetic poles, and windings of the first VR resolver are coiled such that the output of secondary windings provided on the first plurality of stator magnetic poles is substantially the same as the output of the predetermined group of stator magnetic poles.
