摘要:
A rotation-angle detecting device includes: an angle detecting unit that detects a rotation angle of a rotating body on the basis of sinusoidal wave signals that multiple sensors arranged to have a phase difference output according to the rotation angle of the rotating body; and a resolution setting unit that allows change of a resolution of the rotation angle detected by the angle detecting unit.
