Abstract

Dans un moteur a reluctance est prevu un support mobile, par exemple un rotor (1), un pendule (14) ou un piston (16), muni d'au moins un aimant (2). A cet aimant (2) mobile avec le support (1, 14, 16) est associe, dans un point de rencontre situe sur la peripherie de sa trajectoire, au moins un aimant fixe (3, 3') qui, commande par le mouvement du support, exerce sur l'aimant mobile (2), lors de chaque rencontre avec celui-ci, une impulsion de mouvement repulsive et/ou attractive. Afin d'ameliorer le rendement d'un tel moteur, l'aimant fixe (3, 3') et/ou l'aimant mobile (2) sont places, au cours du mouvement du support, dans un etat delivrant une impulsion. L'aimant delivrant l'impulsion (3, 3') peut a cet effet etre un aimant deplacable mecaniquement dans une position delivrant une impulsion de mouvement ou un electro-aimant excitable temporairement, dont le deplacement, respectivement l'excitation, est pilote par intermittences par le mouvement du support (1, 14, 16).In a reluctance motor, a mobile support is provided, for example a rotor (1), a pendulum (14) or a piston (16), provided with at least one magnet (2). At this magnet (2) movable with the support (1, 14, 16) is associated, in a meeting point located on the periphery of its path, at least one fixed magnet (3, 3 ') which, controlled by movement of the support, exerts on the mobile magnet (2), upon each encounter with the latter, a repulsive and / or attractive impulse of movement. In order to improve the efficiency of such a motor, the fixed magnet (3, 3 ') and / or the mobile magnet (2) are placed, during the movement of the support, in a state delivering a pulse. The magnet delivering the pulse (3, 3 ′) can for this purpose be a magnet movable mechanically in a position delivering a pulse of movement or a electromagnet temporarily excitable, the displacement of which, respectively the excitation, is controlled by intermittently by the movement of the support (1, 14, 16).

Description

Magnet motor

The invention relates to a magnet motor with a movable carrier equipped with at least one magnet and at least one fixed magnet associated with a meeting point in the path of movement of this movable carrier magnet, which in steady, synchronous movement during the movement of the carrier Movement of this carrier corresponds to = the sequence controlled by the movement of the carrier exerts a movement impulse upon the respective encounter with the carrier magnet.

A magnetic motor of this type has become known from French Patent No. 2,335,991. A rotor, to which at least one stationary permanent magnet is assigned, serves as the carrier for at least one movable permanent magnet, in such a way that the same poles of the two permanent magnets face each other. An adjustable shield made of a magnetically neutralizing iron is arranged between the stationary permanent magnet and the rotor. When the rotor is rotated and the movable permanent magnet approaches the fixed permanent magnet, the repulsive effect is canceled by the shield, but as soon as the movable magnet passes the fixed magnet, the shield is pulled up, so that the repulsive magnetic effect movable magnet and the rotor on which it is attached, a pulse in

Direction of rotation granted. The object of the present invention is to improve the efficiency of such a magnet motor and the invention is essentially based on the knowledge that this can be achieved better and more effectively by a controlled periodic change in the state of at least one of the magnets than by an intermediate one this magnet movable shield.

According to the invention, in the case of a magnetic motor of the type described at the outset, the stationary and / or the movable magnet itself is placed in a pulse-emitting state in the constant sequence controlled by the movement of the carrier.

For this purpose, the respective pulse-emitting magnet can be mechanically adjustable into a movement-pulse-emitting position or this pulse-emitting magnet can be designed as a temporarily excitable electromagnet, the excitation of which is controlled intermittently by the movement of the carrier.

The magnet which can be put into a pulse-emitting state can, within the scope of the invention, be put into a state which emits a repulsive pulse when passing the meeting point, but under certain circumstances an even higher efficiency may be achieved by the pulse-emitting magnet approaching the meeting point in a state giving a tightening impulse, then in the area of the meeting point into a neutral state and finally when passing

Meeting place can be put into a state giving off a push-off impulse. A device controlled indirectly by the movement of the carrier, for example via a transmission, an electrical or electronic relay, is advantageously provided for adjusting or exciting the pulse-emitting magnet.

In the following the invention will be explained with reference to drawings which illustrate some embodiments of the subject of the invention for example. It shows

1 shows a magnet motor according to the invention with a rotor 1 as the carrier of a carrier magnet

2, the movement path of which two stationary magnets 3 and 3 'are peripherally assigned, each corresponding to the rotary movement of the rotor 1 from the position of the carrier magnet

2 corresponding neutral position, which was indicated by dashed lines, can be mechanically adjusted to a position that emits motion impulses. The rotary movement of the rotor 1 is a simple mechanical on the shaft 4

Transmission 5 transmitted, which ensures via the shafts 6, 6 'that the movements of the magnets 3 and 3' exactly on the rotation = Movement of the passing magnet 2 can be coordinated, as follows:

As soon as the carrier magnet 2 - as shown in full lines - comes to lie opposite the stationary magnet 3, for example with its north pole, in the course of the rotation of the rotor 1, this is adjusted from its neutral position indicated by dashed lines to the position shown in full lines in the case of it faces the north pole of the carrier magnet 2 with its north pole, so that it repels it and gives the carrier on which it is fastened, that is to say the rotor 1, a movement impulse indicated by the arrow 7.

The carrier magnet 2 on the rotor 1 now arrives at the stationary magnet 3 ', which, as soon as the carrier magnet 2 approaches, must have the position in which its south pole attracts the north pole of the carrier magnet 2 and the rotor 1 thereby indicates an arrow 8 next impulse is given. While the carrier magnet 2 is moving past, the stationary magnet 3 'is adjusted via the neutral, broken, inactive position into a repulsive position facing the rotor 1 with the north pole, so that the rotor 1 - as described above - has a pulse again is conveyed in the direction of arrow 9. The carrier magnet 2 moves further into the area of influence of the fixed magnet 3, which has meanwhile been adjusted to the position in which it faces the rotor 1 with the south pole, so that it attracts the north pole of the carrier magnet 2 and thereby gives the rotor 1 the impulse 10 . Now the processes described above are repeated in the area of the fixed magnet 3 in a constant sequence. When they are adjusted, the peripheral stationary magnets = 3.3 'can, if necessary, perform a rotational movement synchronous with the rotation of the rotor 1 in order to exert their intended effect on the carrier magnets 2.

The principle of operation is basically the same when designing the magnet motor according to FIG. 3. Only the adjustment of the fixed magnets 3 and 3 'is different = loaned: they can be moved in vertical guides 11 in order to be adjusted and they become - For example mechanically - adjusted upwards and downwards from a plate 12 rotatably connected to the rotor 1 by means of a link 13.

Instead of the fixed magnets 3, 3 ', the portable carrier magnet 2 mounted on the rotor 1 could also be adjusted within the scope of the invention, but the execution of this adjustment is mechanically more complicated and therefore less recommendable. An electronically controlled adjustment of this carrier magnet in the course of the rotation of the rotor would be conceivable.

The number of stationary peripherally arranged magnets can be enlarged as desired within the scope of the invention, as can the number of magnets arranged on the movable carrier. Merely for the sake of simplicity and clarity, only one carrier magnet and only two assigned stationary magnets are shown and explained in the illustrated exemplary embodiments; the more magnets there are and work together, the better the engine's performance and the smoother its operation. FIG. 4 shows the application of the inventive concept to an oscillating, a back and forth movement from = leading carrier 14, which is pivotally mounted about a joint 15 and carries the carrier magnet 2, to which the two movable impulses guided in fixed guides 11 giving magnets 3 and 3 * are assigned, which can be shifted from a position facing the carrier magnet 2 to the north pole in constant alternation via a neutral position to a position bringing the south pole into effect. The mode of operation is, as described in the case of FIGS. 1 to 3, such that the adjustable, fixed magnets 3, 3 'convey pulses to the carrier magnet 2 in a constant sequence. The phase of pulse 8 is shown and the following phase of pulse 8 is indicated by dashed lines.

Finally, basically the same also applies to the variant according to FIG. 5, in which the movable carrier is embodied by a piston 16, which can itself be designed as a carrier magnet 2 and is guided in a cylinder 17 in order to execute a reciprocating movement therein.

In the embodiments according to FIGS. 4 and 5, the movements of the magnets 3, 3 'are preferably controlled electronically as a function of the movement of the carrier.

According to FIG. 6, the carrier magnet 2 is assigned a stationary electromagnet 3 with a power supply 18. The electro = magnet 3 is over a. Interrupter (not shown) in the power supply 18 is always excited when it passes through the south pole of the carrier magnet 2, in order to then give the carrier magnet 2 a repulsive pulse in the direction of rotation 7 of the rotor 1 granted.

The embodiment according to FIG. 7 works similarly, in which the rotor 1 is located within an electromagnet 3 designed as a yoke and is peripherally equipped with a ring-shaped permanent magnet, the carrier magnet 2. In this case too, the electromagnet 3 receives current as a fixed magnet by means of an interrupter in the power supply 18 when the poles of the same name of the carrier magnet 2 have passed the poles of the electromagnet 3.

Also in the embodiments according to FIGS. 6 and 7, it would be conceivable to use the excitation of the electromagnet both to attract and to repel the movable carrier magnets by a constant pole change.

Although the magnet 3 assigned to the movable carrier was generally referred to as stationary above, within the scope of the invention there is in principle the possibility of also arranging it on a movable carrier, in which case the two trajectories must then have a common meeting point.

The technical details of the invention can be modified in many ways, but the principle that the movement of the carrier obtains its impulses from magnets which are in changing states and are arranged on the periphery of the path of movement of the carrier magnet is of essential importance.
