Title:
MAGNETIC GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/011809
Kind Code:
A1
Abstract:
Provided is a magnetic gear device in which a force transmitted between a first magnet row, a second magnet row, and a magnetic body row is increased. A magnetic gear device provided with: a first magnet row in which a plurality of magnetic pole pairs are arranged at substantially equal intervals along a specific direction; a second magnet row disposed so as to face the first magnetic row, the second magnet row having a plurality of magnetic pole pairs arranged at substantially equal intervals along the specific direction at a smaller (or greater) pitch than that of the first magnet row; and a magnetic body row arranged between the first magnet row and the second magnet row, the magnetic body row having a plurality of magnetic bodies arranged at substantially equal intervals along the specific direction; the distance between the magnetic bodies and the second magnet row in which the magnetic bodies and the second magnet row face each other being configured so as to be smaller (or greater) than the distance between the magnetic bodies and the first magnet row.
