ABSTRACT:
A rotating machine is provided of the type in which the rotor includes a plurality of radial permanent magnets joined by pole pieces in the form of arcs of a circle, wherein the pole pieces have slots therein which oppose the propagation of magnetic fluxes in any direction other than the substantially radial direction of the concentration of the armature flux. The result is a notable increase in the power-to-weight ratio of the machine.
