Title:
ROTATION DETECTOR
Document Type and Number:
WIPO Patent Application WO/2023/276488
Kind Code:
A1
Abstract:
Provided is a rotation detector that facilitates proper power generation of a power generation element. A rotation detector (14) includes a pair of magnets (20), (22) that rotate with a rotary shaft, and a power generation element (24) that generates power by means of changes of a magnetic field caused by the pair of magnets (20), (22) rotating with the rotary shaft. The pair of magnets (20), (22) are arranged on both sides of a rotation axis A of the rotary shaft so as to be spaced apart in a first orthogonal direction, which is orthogonal to the rotation axis A. The N pole and the S pole of each of the pair of magnets (20), (22) are arranged along the first orthogonal direction such that the N pole is located on one side in the first orthogonal direction.
