<p>Upon detecting a peak value from output signals (V1, V2) of one of either a first or a second magnetic sensor (21, 22), an rotation angle computation device (20) identifies, on basis of an amplitude compensation table corresponding to the one magnetic sensor for which the peak value was detected, a pole number of a magnetic pole sensed by the magnetic sensor. Then, based on the identified pole number and a magnetic pole identification table, a pole number of a magnetic pole sensed by the other magnetic sensor is identified. The pole numbers of the magnetic poles sensed by the respective magnetic sensors (21, 22) are thus identified, and the rotation angle computation device (20) compensates the output signals (V1, V2) of the respective magnetic sensors (21, 22) using amplitude compensation gains (G1, G2) corresponding to the sensedmagnetic poles (magnetic pole pair).</p> |
