Abstract:
1. A motor by selective interaction of magnetic fields of permanent magnets, comprising in combination: a first rotor arranged to rotate about a main shaft supported in a frame; a plurality of first permanent magnets fixed to said first rotor and spaced at equal angular intervals around its periphery, all the aforementioned first permanent magnets having the same pole on an outer side farthest from said main shaft; at least a second rotor arranged to rotate about a secondary shaft supported in said frame and parallel to the main shaft; a plurality of second permanent magnets fixed to said second rotor and spaced at equal angular intervals around its periphery, all the aforementioned second permanent magnets having the same pole on an outer side farthest from said secondary shaft and equal to the pole arranged in said outer side of the first permanent magnets of the first rotor; mechanical movement transmission means linking the first and second rotors to force them to rotate in opposite directions and at tangential speeds selected such that the first and second permanent magnets of the first and second rotors are arranged facing each other temporarily and consecutively during rotation; a magnetic screen arranged partially between the first and second rotors, said magnetic screen being formed by at least two superimposed permanent magnet plates with equal poles on their contacting faces and equal poles on their outer faces, the poles on their outer faces being equal to the poles on the outer sides of the first and second permanent magnets of the first and second rotors to interrupt or mitigate a magnetic interaction between the first and second permanent magnets in an upstream portion of their trajectories; and a conventional type auxiliary motor connected to the motor by selective interaction of magnetic fields such that said auxiliary motor can supply power to the motor by selective interaction of magnetic fields during a startup period and/or in load periods in which the load exceeds a pre-established threshold.
