ABSTRACT:
Higher-order Halbach permanent magnet arrays that produce higher flux densities in the air gaps of electromotive machines are described. In one embodiment, a second order “Hyper” Halbach array includes a plurality of magnets arranged immediately adjacent to each other so as to define a rectangular matrix having rows and columns in which the respective magnetic fields of a first row of the array are arranged so as to define a conventional first order Halbach array, and, proceeding in a column direction of the array, the respective magnetic fields of the magnets of each of a second and succeeding rows of the array are respectively rotated counter-clockwise about an axis perpendicular to the column direction of the array through successive 90 degree rotations relative to those of the immediately preceding row.
