Title:
回転角度検出装置
Document Type and Number:
Japanese Patent JP6530797
Kind Code:
B2
Abstract:
A rotation angle detecting device includes: a rotating part rotating integrally with the rotating shaft and including a detected portion; an A-phase detector detecting change of a physical quantity caused by rotation of the rotating part, inside a first detection field over the detected portion and outputting an A-phase signal; and a B-phase detector detecting change of the physical quantity caused by rotation of the rotating part, inside a second detection field located over the detected portion and outputting a B-phase signal that is out of phase with the A-phase signal. The second detection field is shorter than the first detection field with respect to the direction perpendicular to the rotating direction of the rotating part.
