  • Patent number: 4516046
    Abstract: A continuous current electric machine with a cylindrical air gap and with permanent magnet stator excitation in which stacked sheets forming the stator of the continuous current machine have closed cut-outs of a polygonal contour extending therethrough such that each closed cut-out extends into the immediate proximity of at least one of two ends of an effective region of a pole forming the air gap and leaves only a very narrow strip of the sheet between the cut-out and the air gap. At least one magnetic plate, preferably of a rare earth, is inserted in each cut-out to thereby form a permanent magnet pole. Each cut-out comprises a series of rectangular slots in the shape of a V or a U, the opening of which is oriented toward the corresponding effective region of a pole. One embodiment includes at least one wound pole formed on the stacked sheets so as to equip the electric machine with a hybrid, permanent magnet and wound inductor.
