The invention relates to a technique making it possible to obtain a movement maintained starting from the force repulsion exerted by magnetic dipoles in oppositions, placed respectively on a rotor and a stator and between which is laid out a carry-shield, carrying on its surface, of the ferromagnetic elements turning in against direction of the rotor. At the time of the revolution of the rotor, the shields (1) systematically come to occult the dipoles (2) carried by the rotor (4) and the stator (5), at the time with those approach one the other, thus preventing their repulsion at this stage, then, at the time when the dipoles (2) are aligned on their axes, the shields (1) are then withdrawn, which makes it possible the force of repulsion between these dipoles (2) to become driving. This technique according to the invention is particularly intended for the construction of the engines driven by permanent magnets.
