Abstract
To provide an angle detection apparatus which can reduce the error of the angle which is caused by the eccentricity, by performing the reduction processing about smallest possible number of frequency bands and the lowest possible order of frequency band. An angle detection apparatus performs a first-order component reduction processing which reduces a first-order component which is a component of one rotation period in a mechanical angle of the rotor, to each of the first system two output signals; and calculates a first angle of the rotor, based on the first system two output signals to which the first-order component reduction processing was performed.
