Abstract

See full text

A resolver body including a rotor having Nx (Nx is a natural number) salient poles, a stator facing the rotor and having Ns (Ns is an integer equal to or larger than 3) teeth arranged in a circumferential direction, and an excitation winding and two phases of output windings wound on each tooth; and an excitation circuit configured to apply voltage to the excitation winding. The excitation winding and the two phases of output windings wound on each of Nsm (Nsm is an integer equal to or larger than 2) teeth among the Ns teeth are set to be of a main system. The excitation winding and the two phases of output windings wound on each of Ns-Nsm teeth are set to be of a sub-system. The number Nsm of the teeth corresponding to the main system is larger than the number Ns-Nsm of the teeth corresponding to the sub-system.
