Abstract:
There are arranged a sensor magnet fixed to a rotary shaft and configured to generate a magnetic field for detecting a rotation angle, and a plurality of sensors arranged so as to be opposed to the sensor magnet and each configured to output a sine signal and a cosine signal in accordance with the magnetic field. First and second sensors are arranged on two radial lines different from each other, respectively, out of three radial lines dividing a circumference about the rotary shaft of the sensor magnet into six equal parts. An angle calculation unit is configured to carry out calculation so that 3n-th (n is a natural number) order harmonic components out of odd-order harmonic components of each of the sine signal and the cosine signal output by the first and second sensors cancel one another, to thereby calculate the rotation angle.

Claim (Index 10):
An angle detection device according to  claim 8 , wherein the angle calculation unit is configured to multiply any one of the corrected sine signal and the corrected cosine signal by a ratio between amplitudes of fundamental waves of the corrected sine signal and the corrected cosine signal, to thereby calculate the rotation angle.
