摘要：A variable reluctance resolver has a rotor with magnetic poles with 2× orgreater axis combination angles, and is structured so that reliable and accurate zero
point detection can be carried out. Concave and convex portions are provided on at leasttwo, but fewer than all, of the magnetic poles of the rotor, and the zero point detectionwinding is provided on a plurality of electrical poles of the stator. Two or more zeropoint detection signals are generated simultaneously by a plurality of zero point
detection windings. Therefore, even if a portion of the zero point detection signals is lost,the zero point can still be identified based on the correlation between the two or morezero point detection signals.
