Title:
POSITION SENSOR AND POSITION DETECTION METHOD
Document Type and Number:
Japanese Patent JP2022021022
Kind Code:
A
Abstract:
To provide means for suppressing unintended operation of an operation object caused by erroneous detection of a rotational position because of an influence of an external magnetic field when detecting a position of a rotor by using a magnetic sensor.SOLUTION: A position sensor includes: a magnet rotated with a rotor; plural magnetic sensors 21, 22 for detecting magnetic flux generated from the magnet; and detection parts 25, 30 for detecting a rotational angle of the rotor and abnormality in the magnetic sensors 21, 22 on the basis of detection values by the magnetic sensors 21, 22. The detection part 30 detects a rotational angle of the rotor on the basis of a detection value for minimizing the rotational angle of the rotor corresponding to each detection value from among detection values by the plural magnetic sensors 21, 22.SELECTED DRAWING: Figure 5
