Abstract
Official abstract text for this publication.
Magnet array structure and method for forming magnet array structure that includes a first linear magnet array including a first magnet arrangement, in which the first magnet arrangement is consecutively repeated and a second linear magnet array including a second magnet arrangement, in which the second magnet arrangement is consecutively repeated. The first magnet arrangement includes a plurality of first magnetic elements having non-uniformly dimensioned widths in a length direction of the first magnet arrangement and the second magnet arrangement includes a plurality of second magnetic elements having non-uniformly dimensioned widths in a length direction of the second magnet arrangement. The first linear magnet array is arranged parallel to the second linear magnet array so that the first magnet arrangement is linearly offset from the second magnet arrangement.

What is claimed: 1. A magnet array structure, comprising: a first linear magnet array comprising a first magnet arrangement, in which the first magnet arrangement is consecutively repeated; and a second linear magnet array comprising a second magnet arrangement, in which the second magnet arrangement is consecutively repeated, wherein the first magnet arrangement includes a plurality of first magnetic elements having non-uniformly dimensioned widths in a length direction of the first magnet arrangement, wherein the second magnet arrangement includes a plurality of second magnetic elements having non-uniformly dimensioned widths in a length direction of the second magnet arrangement, and wherein the first linear magnet array is arranged parallel to the second linear magnet array so that the first magnet arrangement is linearly offset from the second magnet arrangement. 2. The magnet array structure according to claim 1 , wherein adjacent first magnetic elements have magnetic flux orientations offset 45° from each other, and wherein adjacent second magnetic elements have magnetic flux orientations offset 45° from each other. 3. The magnet array structure according to claim 2 , wherein the magnetic flux orientations across the first magnet arrangement rotate counter-clockwise, and wherein the magnetic flux orientations across the second magnet arrangement rotate clockwise. 4. A method for forming a magnet array structure, comprising: forming a first linear magnet array comprising a first magnet arrangement, in which the first magnet arrangement is consecutively repeated; forming a second linear magnet array comprising a second magnet arrangement, in which the second magnet arrangement is consecutively repeated, wherein the first magnet arrangement includes a plurality of first magnetic elements having non-uniformly dimensioned widths in a length direction of the first magnet arrangement, and wherein the second magnet arrangement includes a plurality of second magnetic elements having non-uniformly dimensioned widths in a length direction of the second magnet arrangement; and arranging the first linear magnet array parallel to the second linear magnet array so that the first magnet arrangement is linearly offset from the second magnet arrangement. 5. The method according to claim 4 , wherein the forming of the first magnet arrangement comprises arranging the plurality of magnetic elements so that adjacent first magnetic elements have magnetic flux orientations offset 45° from each other, and wherein the forming of the second magnet arrangement comprises arranging the plurality of magnetic elements so that adjacent second magnetic elements have magnetic flux orientations offset 45° from each other. 6. The method according to claim 5 , wherein the magnetic flux orientations across the first magnet arrangement rotate counter-clockwise, and wherein the magnetic flux orientations across the second magnet arrangement rotate clockwise.
