ABSTRACT:
Four pole pieces embedded in the cylindrical periphery of a non-magnetic rotor disk are connected with each of a number of magnets embedded in the disk in circumferentially distributed positions spaced from the rotor shaft and from the disk periphery. Of these pole pieces, one circumferentially interleaved pair is connected with one pole of the magnet by a magnetically conducting yoke strip embedded in one circular face of the disk and the other pair is similarly connected with the other pole of the magnet. The spacing between the first and second pole piece is equal to the spacing between the third and fourth and less than that between the second and third, the latter spacing being equal to the spacing between groups of pole pieces associated with different magnets, for the case of a uniformly timed firing sequence of a multicylinder engine.
