ABSTRACT A controlled electric drive (CED) device is disclosed which converts electric current into accurately controlled, simple and complex translatory and rotary motion. The device comprises a pair of rectangular magnetic poles of different polarity arranged adjacent, parallel, and congruent to each other with a relatively narrow gap therebetween, providing an essentially uniform magnetic field between the pole faces. A driver conductor is arranged to move freely between the magnetic pole faces in such a manner that an electric current running through the driver conductor will tend to move the conductor out of the magnetic field at right angles to the conductor and to the direction of the magnetic lines of force defining the magnetic field. The (CED) device also has a controller conductor which in a preferred embodiment is wound in a flat, essentially rectangular spiral fixed adjacent to, and insulated from, the driver conductor and arranged so that its longitudinal direction is parallel to the driver conductor, with direct current flowing in opposite directions. Alternatively, there is provided a multiplicity of controllers comprising single conductors, multiple conductors, rectangular magnets, shaped magnets, and shaped magnetic gaps. A plurality of such CED devices can be arranged in various arrays so as to provide for the tracing of complex patterns in two and three dimensions. Among the uses of this device when equipped with a suitable tool are cutting, piercing, marking and other similar operations.
