Title
(EN) ROTATION ANGLE DETECTION DEVICE
Abstract
(EN)

A first rotation angle computing unit computes a first rotation angle corresponding to a rotation angle of a rotor based on an output signal of a first magnetic sensor and an output signal of a second magnetic sensor. A second rotation angle computing unit computes a second rotation angle corresponding to the rotation angle of the rotor based on the output signal of the second magnetic sensor and an output signal of a third magnetic sensor. A rotation angle selection unit determines a final rotation angle using the first rotation angle and the second rotation angle.
