ABSTRACT:
A permanent magnet rotor configuration which produces two magnetic poles. Two pairs of axial slots are provided in which permanent magnets are arranged about the rotor shaft. A third, diametrically opposed pair of slots is provided which extend radially outwardly and in which permanent magnets are disposed. Off-axis magnetic bridges are formed on either side of the third slots, separating them from the first and second sets of slots.
