发明名称 VARIABLE RELUCTANCE RESOLVER AND ROTATION ANGLE SENSOR USING IT
摘要 PROBLEM TO BE SOLVED: To provide a resolver capable of acquiring a detection signal of a double axial angle 1X highly accurately by reducing an influence of decentering between a stator and a rotor, and to provide a rotation angle sensor using the resolver. SOLUTION: In this VR resolver 17, the rotor is constituted by providing the first rotor part provided with salient poles to the optional number of n of three or more centered at the axis at equal angles and the second rotor part provided with salient poles to the number of (n-1) centered at the axis at equal angles, and a plurality of magnetic poles are provided inside the stator, and exciting winding, and nX output winding and (n-1) output winding for taking out a sin output and a cos output having phases different by 90 degrees are provided. This rotation angle sensor 10 takes a sin(nθ) output signal and a cos(nθ) output signal of double axial angle nX output winding and a sin((n-1)θ) output signal and a cos((n-1)θ) output signal of double axial angle (n-1)X output winding, converts them into double axial angle 1X resolver signals, and outputs the result.
