In one embodiment, a magnet array and ironless winding for a motor is provided which has an array of permanent magnets being arranged such that flux from the permanent magnets reinforce on one side of the array and substantially cancel on an opposite side of the array, the array further includes flux concentrators forming poles on the reinforcing side of the array, and such that a magnetic moment at the poles is oriented generally perpendicular to the reinforcing side of the array, the winding being adjacent to the array and comprising conductor bundles having a generally rectangular cross-section arranged such that a long side of the generally rectangular cross-section is transverse to a direction of magnetic field lines at the poles.

Flux concentrator for ironless motor

In one possible embodiment, a magnet array for a motor is provided which has an array of permanent magnets being arranged such that flux from the permanent magnets reinforce on one side of the array and substantially cancel on an opposite side of the array, the array further includes flux concentrators located at poles on the reinforcing side of the array.
