ABSTRACT:
A high-accuracy, 1X VR resolver includes a first rotor portion having (N−1) salient poles, where N is an arbitrary integer not less than 3, a second rotor portion having N salient poles, a first stator portion having an input coil and an output coil for a shaft angle multiplier of (N−1)X are provided, and a second stator portion having an input coil and an output coil for a shaft angle multiplier of NX. A first resolver unit composed of the first rotor portion and the first stator portion, and a second resolver unit composed of the second rotor portion and the second stator portion are disposed in front and rear stages, respectively. The output coil of the stator portion in the front stage is connected to the input coil of the stator portion in the rear stage in such a manner that the output coil of the stator portion in the rear stage outputs an output signal for a shaft angle multiplier of 1X.
