Abstract
The present invention relates to a phase modulation-type redundant two-phase-output resolver, an excitation signal () is applied to an excitation winding () of an annular stator () having a VR-type rotor () disposed therein, and a two-phase output signal () is outputted from first and second output windings () that are provided in the annular stator (), the excitation winding () is made up of first and second excitation windings () of mutually different phases, and the excitation signal () has two phases, and even in a case where a break occurs in only any one winding from among the first and second excitation windings () and the first and second output windings (), at least a one-phase output signal can be obtained.
