Description

The following invention relates to a magnetic device comprising at least one stator and at least one translator, which translator is movably mounted relative to the stator during operation of the magnetic device according to the invention in a continuously variable translator movement direction.

The operation of electric motors according to the prior art, in particular the operation of rotary motors is characterized in that the field strength of the translator and the stator is controlled in dependence on the externally acting on the electric drive force. The distance of the translator to the stator is not changed during operation of an electric motor according to the prior art.

One of the objects of the invention is to provide a magnetic drive with particularly good efficiency. Furthermore, it is an object of the invention to provide a magnetic drive with particularly positive properties such as high smoothness, as uniform as possible movement of the translator.

A smooth running or as uniform as possible movement of the translator can be accomplished in the prior art by the use of high compared to the total weight of the magnetic device according to the invention high balancing weights. However, the use of such balancing weights is generally to be considered disadvantageous, since additional masses, in particular the balancing weights must be accelerated.

In addition, it is possible to ensure the above-mentioned properties of a magnetic drive by using a control device.

The object of the present invention is to achieve the abovementioned properties of the magnetic drive according to the invention by a modification of the magnetic drive in comparison with magnetic drives according to the prior art without the use of additional means or devices.

The invention disclosed below equally relates to the use or design of the magnetic drive according to the invention as a drive element, - 1 - ················································································· * * «· • I * II * *·· • * * * · · ·« I «+« * «* #« «· ·

Generator or as a resistance element. In the latter case, an externally excited movement of the translator is prevented by the activation of the magnetic field and the force state acting between the stator and translator.

According to the invention, this is achieved by the approaches disclosed below. It is not excluded by the disclosure of the invention that the approaches discussed below are combined.

As part of a possible approach, the inventive

Magnetic device comprises a control device for controlling a distance r> 0 (in words: r greater than zero) of the translator to the stator during operation of the magnetic device with respect to the force state resulting between stator and translator.

In the context of a further approach, the inventive

Magnetic device further comprise a control device for controlling the state of force as a function of the distance r> 0.

The control of the minimum distance r as a function of the acting

Force state and / or the control of the force state as a function of the distance r can also be effected in dependence on external forces acting on the magnetic device according to the invention forces.

The magnetic device according to the invention is characterized in that the

Translator and the stator has a distance r even when not in use, so that they do not act as a magnet, thus as individual magnets. The Magnetvom'chtung may for this purpose have a locking device by means of which a movement of the translator relative to the stator when not in use of the magnetic device can be prevented.

The translator is passably movable in the translator travel direction along a translator polygonal path relative to the stator, substantially the stator. The extended translator path does not pass through the stator but passes the stator. - 2 - «I« · II ·· ······· I »9 · · * # *« * «» ·· * · ·· * • ·· I · * · »« · «f * 4« 4 «« ·

The stator and the translator may comprise a magnet part and a layer enclosing the magnet part or a spacer preventing a contact of the magnet parts of the stator and translator, so that at a distance r = 0 the stator and the translator, but not the magnet parts of the stator and the translator to contact.

The distance r can be further set by the control device depending on the temporary properties of the magnets. The temporary properties of the magnets can be changed on the one hand by external influences such as heat load, on the other hand controlled by other control devices. For example, the field strength of a magnetic field and the orientation of the magnet can be controlled by methods of the prior art. Furthermore, referring to the standard teaching, the choice of materials and the combination of materials have an influence on the properties of a magnet.

The control device included in the magnetic device of the present invention can control the distance r with respect to the above-mentioned influences and characteristics of the magnets of the at least one stator or the at least one translator.

A polygonal translator trajectory may be characterized in that the movement of the translator has a constantly variable translator travel direction. Possible shapes of a polygonal translator trajectory are a circular shape, the shape of an ellipse and a polygonal line having a starting point and an end point. The trajectory of the translator may be defined by a mechanical constraining system such as a guide unit having a polygonal or linear extension. The translator may be coupled to other movable, in particular rotatably or displaceably mounted elements which form such a mechanical constraint system and thus dictate the movement of the translator. The translator may for example be coupled to a lever or a crankshaft. - 3 - «·« «« «« «« ** · * ··· «····« «· ·« «» · ·. * «4« ♦ • · «* · ·· ·· * •« * ♦ 4 4 ♦ * 9 ·· «* * ·· * ·

The magnetic device according to the invention may be such that in partial regions of the translator movement path, a first interaction between the stator and the translator, in further partial regions further interactions between the stator and the translator, are created by the control device. This results in first attraction or repulsion forces and second attraction or repulsion forces between the stator and the translator prevail in the respective areas.

The translator and the stator are to be formed in the prior art of magnetic devices as electromagnets and / or permanent magnets. The magnetic device according to the invention can comprise magnets both with the same field strength and with different field strength as a stator or translator. The use of different field strength magnets includes that both the translator and the stator comprise magnets having a greater field strength than the stator or translator.

The polarity of the stator and of the translator to one another must be such that a repulsive forces and / or forces of attraction comprehensive force state is created by a different or the same polarity of the stator and translator, so that a movement of the translator is caused by the attractive forces and / or repulsive forces. The polarity of stator and translator for generating the attractive and repulsive forces substantially corresponds to the prior art.

The invention further includes that the polarity of stator and translator in dependence on the distance between the stator and the translator, in particular bet a distance r between the stator and translator takes place.

One possible application of the invention disclosed herein, in addition to providing a magnetic device with a particular high efficiency in the control of magnetic devices according to the prior art. Due to unavoidable inaccuracies, the distance between the stator and - 4 - · «·« ····

Translator a variable size. A variance of the distance may be due to production or due to the changing material properties.

The invention disclosed herein essentially shows the relationship between the distance r and the power of the magnetic device according to the invention or a magnetic device according to the prior art. An application of the invention is in the control of a magnetic device as a function of the measured distance, so that the magnetic device provides a defined performance.

The translator may be passably movable in the translator travel direction along a translator polygonal path relative to the stator, substantially the stator. The extended translator path does not pass through the stator but passes the stator.

The following mathematical discussion of the relationship of the distance r and the power output from the magnetic device is limited to the special case of a polygonal trajectory of the translator such that the translator trajectory and translation direction of a translator moved between two stators aligns congruently and parallel to the degrees of connection of the stators is.

In the case of a mathematical discussion of a deviating temporary movement of the translator, the corresponding factors are to be modified according to the laws of trigometry.

The distance r, in particular a minimum distance r, can be set by the control device with reference to the state of force that is established between a stator and the translator such that a resultant force state acting on the translator is a maximum at a position Xt of the translator, wherein for the the following relationship applies to forces acting on the translator: - 5 -

Magnetic pole strengths are calculated using equations (4.4a) for the first stator, (4.4b) for the second stator, and (4.4c) for the translator. The calculation of the magnetic pole strengths involves the calculation of the total magnetic induction field at the poles. This is done using equations (4.2a) and (4.2b).

Equation (4.5) is a function of the position of the translator between the stators. The resultant force state acting on the translator is composed of the repulsive force acting between the first stator and the translator and the attractive force acting between the second stator and the translator.

The above mathematical discussion further shows that in a position of the translator to a stator, the attraction and - after reversal of the stator or the translator - the repulsive force are different.

The translator may be rotatable relative to the stator about a point of rotation.

The magnetic device according to the invention can be characterized in that the translator relative to the stator, further the translator and the stator are moved relative to another fixed point. In a movement of the translator and the stator relative to a fixed point, the translator and the stator can have a direction of movement that is rectified with respect to one another or a direction of movement that is opposite to one another.

It is also possible to move the point of rotation along a trajectory, such as the translator trajectory, such that the translator experiences movement and rotation relative to the stator.

The control device may comprise a device for a movable stator bearing of the stator and / or a device for a movable translator bearing of the translator with respect to the distance of the translator to the stator. 21 * Φ Φ Φ Φ Φ Φ Φ ♦ i φ ι Φ Φ · * Φ 4 Φ 4 Φ 4 Φ Φ Φ

The distance of the translator to the stator can be defined by a displacement of the stator or the translator. It should also be explicitly mentioned here, with reference to the following figures and the associated description of the figures, that the magnetic device according to the invention can be characterized by considering the interaction of all the translators and stators in an effective field.

The control device may comprise a device for a fixed stator mounting of the stator and / or a device for a stationary translator bearing of the translator with respect to the distance of the translator to the stator.

A magnetic device comprising translators and stators mounted immovably to one another comprises a control device for controlling the force state acting between the stators and translators. The control of the force state may include control of the interaction between the individual stators and translators.
