Title
(EN) Device for detecting angle of rotation
(ZH) 旋转角检测装置
Abstract
(EN)
Disclosed is a device for detecting an angle of rotation, in which a first angle of rotation calculation section (21) calculates a first angle of rotation (?1) corresponding to the angle of rotation of a rotor (1), in accordance with an output signal (V1) of a first magnetic sensor (11) and an output signal (V2) of a second magnetic sensor (12). A second angle of rotation calculation section (22)calculates a second angle of rotation (?2)corresponding to the angle of rotation of the rotor (1), in accordance with the output signal (V2) of the second magnetic sensor (12) and an output signal (V3)of a third magnetic sensor (13). An angle of rotation selection section (23) obtains the final angle of rotation (?) using the first angle of rotation (?1) and the second angle of rotation (?2).
