Abstract
Official abstract text for this publication.
A motor includes a stationary unit and a rotary unit arranged to rotate with respect to the stationary unit about a center axis extending in an up-down direction. The rotary unit includes a substantially cylindrical rotor holder, a plurality of magnets disposed radially inward of the rotor holder and arranged along a circumferential direction, and a non-magnetic magnet holder fixed to an inner circumferential surface of the rotor holder and arranged to hold the magnets. The magnet holder includes a plurality of pillars extending in the up-down direction and arranged to position the magnets in the circumferential direction, and a first ring and a second ring arranged to interconnect the pillars at positions spaced apart in the up-down direction. The first ring is positioned radially outward of the second ring, and the second ring is positioned radially inward of outer circumferential surfaces of the pillars.
