Abstract
The present invention provides a rotation angle detector capable of detecting a rotation angle of a rotor in the same manner as at normal time even when abnormality such as disconnection or a short circuit occurs, and capable of reducing the number of terminals. When one spatial order cycle of the output winding is an electrical angle of 360°, a phase difference between a first output winding and a second output winding and a phase difference between the second output winding and a third output winding are set at an electrical angle α, and α≠180°×n (n is an integer).
