Document Type and Number:
WIPO Patent Application WO/2017/122677
Kind Code:
A1
Abstract:
The present invention is provided with: a rotor (4) having magnets (16) in which a plurality of N-pole magnets (16N) and a plurality of S-pole magnets (16S) are disposed in order in the rotation direction; and three Hall ICs (50u, 50v, 50w) disposed in a line in the rotation direction so as to face at least a portion of the magnets (16). All of the N-pole faces of the magnets (16) are uniformly magnetized to the N-pole and all of the S-pole faces of the magnets (16) are uniformly magnetized to the S-pole, and the three Hall ICs (50u, 50v, 50w) are each disposed or formed so as to output the same magnetic-pole signal only at a predetermined rotation position of the rotor (4).
