Abstract: A permanent magnet carrier, which could be a rotor or stator of an electric machine, includes a first non-magnetic ring and a second non-magnetic ring. Between the rings are soft magnetic pole elements. The soft magnetic pole elements each connect to the first and second non-magnetic rings and the soft magnetic pole elements are separated from each other by the first and second non-magnetic rings. Permanent magnets are disposed between the soft magnetic pole elements.

Abstract: An electric motor has a first carrier having an array of electromagnetic elements and a second carrier having electromagnetic elements defining magnetic poles. The first and second carriers each define an axis. An airgap is formed between the first and second carriers when in an operational position. An inner thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. An outer thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. The electromagnetic elements of each of the first and second carriers are arranged radially inward of the outer thrust bearing and radially outward of the inner thrust bearing. The inner thrust bearing and the outer thrust bearing are arranged to maintain the airgap against a magnetic attraction of the electromagnetic elements of the first and second carriers.
