ABSTRACT:
Electromagnetic actuators are disclosed for precisely and directly incrementing an output member along a given generally linear path. Included in one actuator is a pair of assemblies, one of which is movable with respect to the other along the given path. A first of the assemblies includes means for producing a first magnetic field extending to the second actuator assembly in a manner generally transverse to the given path. The second actuator includes energizable means alongside the path and for producing a pair of opposed, approximately equal magnetic fields, spaced along the given path. Each of these opposed fields being aligned to cooperate with the transverse field to produce a force between the assemblies tending to centrally locate the assemblies with the transverse field between the pair of opposing fields.
