1. A permanent magnet carrier comprising:
a first non-magnetic ring;
a second non-magnetic ring axially spaced from the first non-magnetic ring;
radially tapered soft magnetic pole elements, the soft magnetic pole elements each connecting to the first and second non-magnetic rings and the soft magnetic pole elements separated by the first and second non-magnetic rings; and
permanent magnets disposed between the soft magnetic pole elements,
wherein both ends of each of the soft magnetic pole elements are fitted in receiving slots in the first and second non-magnetic rings to engage the soft magnetic pole elements to the first and second non-magnetic rings.
