MAGNETO-ELECTRIC GENERATOR OF ELECTRICITY

The utility model refers to magneto-electric power generators with the presence of permanent magnets in them.
The closest device of the same designation to the claimed utility model for the set of features is a magneto-electric generator comprising a permanent magnet, a magnetic circuit, an inductive winding located on the magnetic circuit in the working area of ​​the magnetic field of the magnet and connected to an electrical load, Through the generator inductive winding / prototype - in Kn.I.P. Kopylov "Electric Machines",, M, 1986, textbook for universities, p.286 /.

To the reasons preventing the achievement of the following technical result when using the known device adopted as a prototype, the fact that in the prototype the material-consuming magnetic circuits are used to produce electricity and the energy-consuming magnetic flux regulator made in the form of a power drive of rotation for mutual movement of the magnet and an inductive generator Winding, with a power exceeding the power of the generated electricity from the generator.

The essence of the utility model lies in another design of the magneto-electric generator, namely, in use as the magnetic circuit for this inductive winding of the most closed magnetic permanent magnet, made, for example, in the form of a composite annular magnet, part of which is a magnetic segment with a rectangular hysteresis loop, The magnetic flux regulator through the inductive winding is made in the form of a magnetic resistance controller of the magnetic flux type magnetic flux trigger on the Barkhausen effect and includes this magnetic segment of the magnet, an additional magnetization inductive winding located on this magnetic segment and a voltage regulator electrically connected between this Magnetizing inductive winding and a generator inductive winding through the starting source of electric power, the voltage regulator being made to be adjustable in amplitude and frequency of the voltage, with parameters sufficient to provide the threshold value of the electric current in the magnetizing inductive winding, and the subsequent jump-wise cyclic magnetic reversal of the magnetic segment. (The magnetic effect of Barkhausen-A great encyclopaedic dictionary, M., 1991, vol. 1, p.108).

The technical result is the simplification of the design of the magnetoelectric generator (static electricity generator), increasing reliability, increasing the energy efficiency and efficiency of a known electric power generator using permanent magnets.

Said technical result in the implementation of the utility model is achieved in that in a known device containing a permanent magnet, a magnetic circuit, a generator inductive winding located on a magnetic circuit in the working area of ​​the magnetic field of the magnet and connected to an electrical load, and a magnetic flux regulator via an inductive winding , The feature of which is that the magnet itself is used as a magnetic circuit with a closed magnetic circuit, for example a ring magnet, part of which is a magnetic segment with a rectangular hysteresis loop, the magnetic flux regulator through the inductive winding being a magnetic resistance controller of a magnetic circuit of the type Magnetic trigger on the Barkhausen effect, and comprises this magnetic magnet segment, an additional magnetization reversing coil located on this magnetic segment, and a voltage regulator regulated in amplitude and frequency of the voltage and electrically connected between this magnetizing inductive winding and the generator inductive winding through the starting An electric power source, the voltage regulator being made to be adjustable in amplitude and frequency of the voltage, with parameters sufficient to provide a threshold value of the electric current in the magnetizing inductive winding, and subsequent hopping of the magnetic segment reversal.

FIG. 1 shows a proposed improved magneto-electric power generator, shown in a simplified form.

Information confirming the possibility of implementing a utility model with the above technical result is as follows.

DEVICE OF A MAGNETIC-ELECTRIC GENERATOR BASED ON A RING CONSTANT MAGNET

Fig. 1

The magnetic-electric power generator ( Fig. 1 ) contains an annular permanent magnet 1 (with radial or axial magnetization), a closed magnetic circuit of the magnet 1 , a generator inductive winding 4 located on the magnetic circuit of the magnet 1 itself and connected to an electric load 5 , Magnet 1 includes a magnetic segment 3 with a rectangular hysteresis loop, and a magnetic flux regulator 2 through an inductive winding 4 , which regulator is designed as a magnetic resistance regulator of a magnetic circuit of the Barkhausen magnetic trigger type , which includes this magnetic segment 3 of the magnet 1 , an additional magnetization reversal An inductive winding 6 located on this magnetic segment 3 and a voltage regulator 7 with a control system 8 controlling the amplitude and frequency of the current connected electrically to the reversing coil 6 along its output side. In the power input is connected through the voltage converter 9 to the starting power source (battery) and to the generator inductive winding 4 .

The device works as follows. The appearance of an electromotive force ( EMF ) in the inductive winding 4 from the electromagnetic induction induced in this generator inductive winding 4 placed directly on the permanent magnet 1 with a closed magnetic circuit and receiving electricity from it during the flow of electric current, under the action of the emf induced in it, Load 5 by changing the magnetic flux through it, we carry out by means of cyclic switching of the magnetic flux of the permanent magnet 1 by means of a magnetic trigger 2 operating on the magnetic Barkhausen effect by cyclic reversal of its magnetic segment 3 made of a magnet with a rectangular hysteresis loop from an additional magnetizing winding 7 .

The device can work in stand-alone mode. To this end, we first start this self-excited magneto-electric generator by supplying power from an autonomous electric power source 10 through a voltage converter 9 and a voltage regulator 7 to an inductive magnetizing coil 6 located on the magnetic segment 3 . The magnetic segment 3 and the magnet 1 itself have a magnetic hysteresis loop, therefore, under the influence of the electromagnetic field, the magnetic resistance of the winding 6 changes, and at a certain threshold value and frequency of the magnetizing (demagnetizing) current through the winding 6, the magnetic segment 3 begins cyclically and step-by- Magnetization and magnetic resistance and goes into the operation mode of the magnetic trigger ( Barkhausen effect ). As a result of the cyclic variation of the magnetic resistance of the sector 3, the magnetic flux of the magnet 1 passing through the magnetic segment 3 arises, as a result of which the electromotive force ( emf ) of the electromagnetic induction is induced in the generator winding 3, and in the load 5, an electric current with a modulation frequency of the magnetic Flux of magnet 1 . After increasing this voltage from the winding 4 above the voltage of the starting power source 10 , the regulator 7 starts to consume a portion of the power of the generator winding through the converter 9 , and the starting source 10 switches to the electric charging mode and can be turned off altogether. The device will continue to operate in a completely autonomous mode, and with increasing ampacity of the output voltage, the frequency of the electric current in the winding 6 also increases, since the blocks 7, 8, 9 realize positive feedback on the voltage of the output generator winding 4 . As a consequence, the switching frequency of the magnetic flux 1 , and consequently the magnitude of the emf and its frequency up to a certain limit, depends on the parameters and dimensions of the magnet 1 and its segment 3 and on the adjustment of the control system 8 by the regulator 7 . The amount of generated electricity is determined by the parameters of the emf and the load itself 5 and is limited only by the parameters of the magnets 1, 3 and load parameters 5 .

THE SUBSTANTIATION OF THE USEFUL MODEL

Due to the use of the most permanent magnet 1 as the magnetic circuit of the generator winding 4 , the material consumption decreases substantially and the design of the known magneto-electric generator (prototype) is simplified. Due to the implementation of the magnetic flux regulator through the inductive generator winding 4 in the form of a Barkhausen magnetic trigger on a narrow magnet segment with a rectangular hysteresis loop, the electric power consumption for cyclic change of the magnetic flux in the ring magnet 1 in such an unusual static magneto-electric generator is much lower than the similar energy costs for The creation of emf in the generator winding 4 , since in the proposed utility model it is the magnetic energy of the magnet 1 itself that is used and converted during this switching of the magnetic flux, and the cyclic variation of the magnetization vector and the magnetic resistance of the magnetic segment 3 occurs very low-cost from its rectangular hysteresis loop during a magnetic reversal Segment 3 , which can be narrow and small and occupy in the magnetic circuit of the ring magnet 1 only a few angular degrees in thickness. Due to the positive feedback of the magnetic flux variation of the magnet 1 on the voltage of the generator winding 4 , the device automatically enters a stable generator mode of generating electricity in the winding 4 after its initial start from the source 10 through the regulator blocks 7 and the converter 9 . The control system 8 realizes the control of the device according to a given law.

Thus, the proposed useful model of a magneto-electric generator has significant differences and useful properties in comparison with the given prototype.
