摘要

Improvements in displaceable rotor microelectromotors, in which the magnetic thrust of its excited field used to move the rotor from its initial position of idling to an active, displaced and floating position, and such displacement causes the coupling of the rotor to a train driven; characterized by having co-operating means to control the displacements of the rotor between the idle and active positions, which comprise a spring adapted to return the rotor to the idle position when the engine is not excited but which is the magnetic thrust exceeded when displaced to an active and floating position said spring being of a predetermined force to equalize and neutralize the magnetic thrust when the rotor is in its floating position and a counterweight mounted and connected to the rotor to move parallel but in the direction opposite to the displacement of the rotor, said counterweight being of a predetermined weight whose effective weight equals and neutralizes the weight of the rotor in all the positions of the engine, which, by means of the opposing forces and mutual neutralization of the effective weight of the rotor and the counterweight, the weight of the rotor is eliminated as a factor that changes with the position of the otor, and the rotor-controlled magnetic displacement of the rotor is safe in its coupling and uncoupling actions.
