ABSTRACT:
A variable-reluctance resolver includes a rotor and a stator. The rotor includes axially connected first and second rotor portions. The first rotor portion has n salient poles provided about a center axis at uniform angular intervals, where n is an arbitrary integer not less than 3. The second rotor portion has (n−1) salient poles provided about the center axis at uniform angular intervals. The stator has a plurality of magnetic poles provided on an inner circumferential surface thereof. An excitation coil and output coils for shaft angle multipliers of n× and (n−1)× are provided on the magnetic poles in order to output sine and cosine outputs having a phase difference of 90 degrees therebetween. A rotational angle sensor includes the VR resolver and a calculation section for calculating a resolver signal for a shaft angle multiplier of 1× from signals output from the VR resolver.
