Patent ID: 8692542

Claim:
A VR resolver with a shaft angle multiplier of n× in which n is a natural number of not less than 3, the VR resolver comprising: a stator core having an inside that is provided with a plurality of salient poles; a rotor core rotatable in the inside of the stator core; n magnetic poles provided to the rotor core so as to be equiangular when viewed from an axial direction of the rotor core, n−1 of the magnetic poles projecting in a radial direction, the other having a lower height in the radial direction compared with the n−1 of the magnetic poles; a plurality of sine winding wound portions formed by winding a sine wave detection wire at at least a part of the salient poles; a plurality of cosine winding wound portions formed by winding a cosine wave detection wire at at least a part of the salient poles; and a zero point detecting terminal led from a part of the sine wave detection wire that connects adjacent sine winding wound portions, or a part of the cosine wave detection wire that connects adjacent cosine winding wound portions.
