Abstract

The machine has permanent magnets (4) set radially round the periphery of two discs (16) that have their peripheries in proximity. The discs are synchronized so magnets in each disc repel. A soft iron screen (8) prevents unwanted interaction between the magnets. A coil (9) between the discs at their closest point can be used to start rotation or to collect electric energy from the magnets.

Description

 The present invention consists in obtaining a rotation which can be used either in driving force or in the production of electrical energy.

 Two assemblies are possible using the same excitation system, and can be defined as follows, the first of the crankshaft type, the second of the double rotary table type.

 For the first assembly, use a crankshaft (1) with a double connecting rod (2) so as to have a perpendicular action maintained by ball sleeves (3) or others, at the end of these connecting rods permanent magnets are fixed ( 4) high power of identical poles, so that they repel each other with the fixed magnet (5), or when they go up and they go down if it is about a mounting double opposite rods (13), to prevent the repulsion of approaching, a rotary disc (6) synchronized by angular transmission (7), with a speed ratio 2> 1 or more, is inserted, fitted with a piece of mild steel (8) creating an attraction and protecting the repulsion, and an electromagnet (9) whose tongue-shaped core takes over from the attraction and repulsion protection part of the magnets, until the end of the connecting rod, which as soon as by the speed of inertia the magnets begin to descend, and, by exciting the electromagnet food by a collector (10) and wiper (11) of a power just necessary, allows it a free passage between the magnets, and to let them return in repulsion, obtaining the rotation of the crankshaft and the dynamo (12) (not shown in FIG. 2), whose energy production then makes it possible to self-excite the electromagnet of very low consumption due to its small metallic mass to be magnetized and also to the fact that no one has sought to create significant electromagnetic repulsion, therefore to be able to use the difference in the motive force created, or to produce electrical energy with a larger dynamo, since one can achieve high power by equipping several assemblies in parallel on the same crankshaft with offset excitations, in order to obtain a greater number of actions per revolution, without using greater energy for excitation of the electromagnets.

 And also on large power systems fitted directly on the crankshaft, a dynamo-alternator assembly (14/1 S) without collector for higher electrical energy production.

 The second assembly, uses the same system of a piece of mild steel (8) to create an attraction and protect the repulsion, and of an electromagnet (9), to allow its extraction and to allow free passage to the magnets ( 4) which are mounted on two plates (16) synchronized so that they present themselves at the same time in the median axis, of the same polarity and repelling themselves, the action of attraction and repulsion after the excitation of the electromagnet is identical to the first assembly.

 The advantage of this assembly is that there is no need for a collector since the electromagnet (9) is fixed, but also the fact of being able to install two double plates (17) on the same axes and by the same electro -magnet (9) to simultaneously obtain a double action of high powers.

 The disadvantage is that large diameter discs will be needed, so that the magnets are more attractive, and remain as long as possible in repulsion, this assembly also supports the possibility of its equipment in parallel on several levels and on the same axes with offset actions, for the same consumption of the electromagnets, for example three assemblies like the one defined (FIG. 6).

 This assembly also supports the production of electrical energy with a dynamo-alternator (14/15), and has the advantage of having no collector or wiper on the entire assembly.

 Both systems can have electronic or mechanical excitation management.

 The two systems can be started, either by electric launcher, or by using auxiliary energy which will be cut as soon as the speed allows the energy produced by the dynamo to take over.

 The two systems can also be used directly as an engine with an auxiliary energy source.

 The two assemblies can be produced in series / parallel and obtain high power, they are by definition intended for the use of motive power production, or and, of electric power production.
