Variable flux permanent magnets electromagnetic machine

A rotating electro-magnetic machine comprising concentric stationary and rotating members, at least one first pair of permanent magnets disposed in one of said members for creating a first magnetic flux having a path external to said one of said members through a radial air gap into the other of said members, at least a second pair of permanent magnets disposed on one side of said first pair substantially linearly aligned with said first pair and angularly oriented relative to said first pair such as to create a second magnetic flux in addition to said first magnetic flux, at least a third pair of permanent magnets symmetrically disposed on the other side of said first pair substantially linearly aligned with said second pair and angularly oriented relative to said first and second pairs such as to create a third magnetic flux in addition to said first and second magnetic fluxes, and means for controllably angularly orienting said second and third pairs of magnets relative to said first pair for varying the strength of said first magnetic flux having said external path, wherein each of the magnets of said first pair are bar magnets having transversely aligned opposite polarities, and each of the magnets of said second and third pairs are ring magnets having longitudinally aligned opposite polarities.
