PROBLEM TO BE SOLVED: To provide an iron core structure of a resolver capable of decreasing the diameter and thickness of a high-accuracy VR type resolver.SOLUTION: A VR type resolver includes a stator having stator poles disposed uniformly along the circumferential direction of an annular stator base, and a rotor for changing the reluctance component in a clearance between it and the stator by changing the relative angular position to that of the stator. At least one of the stator and rotor is configured to have a lamination structure in which a plurality of laminations are rotated and stacked. When the number of stator poles is set at P and the phase number is set at N, the lamination angle of each lamination is set at an angle other than the multiple angle of 360°/(P/N). |
