Abstract
A Halbach array is formed from first to third magnets provided to a rotor. Of shortest straight-line distances (clearance distances) between the first to third magnets and a Hall element as facing the first to third magnets after moving relative to the first to third magnets, the shortest straight-line distance between the second magnet and the Hall element is set the longest. In other words, the second magnet is placed at a position offset from the first magnet. In addition, the second magnet may be offset from the third magnet.
