  • Patent number: 6160328
    Abstract: An electric motor 10.sub.vi includes a Cockcroft ring 12 for producing a magnetic field having lines of flux extending in the first direction through an air gap 18. A disc 14 capable of at least two dimensional motion in a plane relative to the Cockcroft ring 12 provides a plurality of conductive paths C.sub.A -C.sub.E. Each path C.sub.A -C.sub.E has a segment 16.sub.A -16.sub.E respectively that extends through the magnetic field in a second direction so that interaction with an electric current passing through a particular segment 16.sub.A -16.sub.E, produces a thrust force acting on the disc 14 via that segment 16.sub.A -16.sub.E. A multi phase toroid shaped transformer 40 induces electric currents to flow in the paths C.sub.A -C.sub.E and thus through the corresponding segments 16.sub.A -16.sub.E. One of the segments, for example 16.sub.A is located relative to a second segment for example 16.sub.E, so that their respective thrust forces do not lie in the same axis.
