Kratek povzetek izumaA brief summary of the invention

Po pričujočem izumu je motorizirano sredstvo opremljeno z visokofrekvenčnim motorgeneratorjem, ki ne potrebuje vzdrževanja in ki je integriran v okrovu vztrajnika motorja z notranjim zgorevanjem. Okrov vztrajnika je zaščiten s tesnili in vodotesno kabelsko povezavo, kar vodi, ki vstopi v plavajoče motorizirano sredstvo, preprečuje dostop v električni motorgenerator in v njegova navitja. Z integracijo električnega motorgeneratorja v okrov vztrajnika je mogoče navedeno napravo na preprost način uporabiti kot generator električnega toka, ko je spojena z delujočim motorjem z notranjim zgorevanjem, ali pa kot v obe smeri delujoči primarni pogonski stroj, ko je spojena z menjalnikom in jo napaja izmenični električni tok primerne jakosti, napetosti in frekvence iz DC/AC pretvornika, priključenega na akumulatorsko baterijo. Motorgenerator jeAccording to the present invention, the motorized means is provided with a high-maintenance, maintenance-free motor generator which is integrated into the flywheel housing of the internal combustion engine. The flywheel housing is protected by seals and a watertight cable connection, which prevents the water entering the floating motorized means from accessing the electric motor and its windings. By integrating the electric motor generator into the flywheel housing, the said device can be easily used as an electrical generator when coupled to a running internal combustion engine, or as a primary drive machine operating in both directions when coupled to a gearbox and powered by AC electrical current of adequate power, voltage and frequency from a DC / AC converter connected to a rechargeable battery. It's a power generator

-2opremljen z rotorskimi poli s permanentnimi magneti, število navedenih rotorskih polov pa je dovolj veliko, da zagotavlja visoko frekvenco generatorja in velik navor motorja tudi pri enoti s sorazmeroma majhnimi dimenzijami. Poli rotorja so prednostno izdelani iz permanentnih magnetov iz redkih zemelj. Visoka frekvenca motorgeneratorja omogoča, da generator ustvarja zadostno električno moč že pri nizki vrtilni frekvenci motorja, tako da lahko dosega polno moč generiranega električnega toka ob nizkem hrupu in nizkem onesnaževanju celo tedaj, ko motor z notranjim zgorevanjem ne poganja motoriziranega sredstva z veliko izhodno močjo. Navitja motorgeneratorja so priključena na DC/AC pretvornik, kadar motorgenerator deluje kot zaganjalnik motorja. V tem primeru je sklopka, ki spaja ročično gred z rotorjem motorgeneratorja, vklopljena. DC/AC pretvornik se krmili z daljinskim krmilnikom, nameščenim na kontrolni plošči motoriziranega sredstva. Predvidena je tudi možnost samodejnega zagona motorja z notranjim zgorevanjem, kadar je napetost akumulatorske baterije prenizka. Kadar naprava deluje kot električni pogon motoriziranega sredstva, se sklopka, ki spaja motor z notranjim zgorevanjem in rotor motorgeneratorja, izklopi, navitja motorgeneratorja pa so vezana in krmiljena enako kot v predhodnem primeru. Prehod iz elektropogonskega načina delovanja motoriziranega sredstva v fazo zagona motorja z notranjim zgorevanjem je lahko izvedena v trenutku z vklopom sklopke. Motorgenerator je lahko uporabljen tudi skupaj z motorjem z notranjim zgorevanjem za pogon motoriziranega sredstva z namenom povečati moč motorja z notranjim zgorevanjem ali za njegovo hitrejše pospeševanje. Navitja motorgeneratorja so povezana tudi z AC-DC usmernikom, ki dovaja enosmerno napetost DC-DC pretvorniku prek enosmernega filtra za reguliranje generirane enosmerne napetosti, za polnjenje akumulatorskih baterij in napajanje DC-AC inverterja, namenjenega napajanju motoriziranega sredstva z izmeničnim tokom konstantne napetosti in frekvence. Z uporabo tega sistema ni potrebe po jermensko gnanemu altematorju za motor z notranjim zgorevanjem, temveč je mogoč motor z notranjim zgorevanjem brez jermenskih pogonov, s čimer se zmanjšajo stroški vzdrževanja in poveča zanesljivost delovanja. Črpalka za morsko vodo je po potrebi gnana z elektromotorjem, katerega vrtilna frekvenca je termostatsko krmiljena. Tudi ločeni električni zaganjalnik ni potreben, s čimer se zmanjšajo cena, dimenzije in teža celotne naprave.-2 Equipped with permanent magnet rotor poles, the number of rotor poles listed is large enough to provide a high frequency generator and high motor torque even with a unit of relatively small dimensions. The rotor poles are preferably made of rare earth permanent magnets. The high frequency of the generator sets allows the generator to generate sufficient electrical power even at low engine speeds, so that it can reach the full power of the generated current in low noise and low pollution even when the internal combustion engine does not drive the motorized motor with high output power. The motorgenerator windings are connected to the DC / AC converter when the motorgenerator acts as a motor starter. In this case, the clutch connecting the crankshaft to the motor generator rotor is engaged. The DC / AC converter is controlled by a remote controller mounted on the control panel of the motorized vehicle. It is also possible to start the internal combustion engine automatically when the battery voltage is too low. When the device acts as an electrically driven motorized means, the clutch connecting the internal combustion engine and the motor-generator rotor is switched off and the motor-generator windings are tied and controlled in the same way as in the previous case. The transition from the electric drive mode of operation of the motorized means to the starting phase of the internal combustion engine can be made at the moment when the clutch is engaged. The engine generator can also be used in conjunction with an internal combustion engine to drive a motorized vehicle to increase the power of the internal combustion engine or to accelerate it faster. The motor-generator windings are also connected to an AC-DC rectifier that supplies DC voltage to the DC-DC converter via a DC filter to regulate the generated DC voltage, to charge the batteries, and to supply a DC-AC inverter designed to supply a DC motorized DC voltage and frequency. . Using this system, there is no need for a belt driven alternator for the internal combustion engine, but an internal combustion engine without belt drives is possible, thus reducing maintenance costs and increasing operational reliability. If necessary, the seawater pump is driven by an electric motor whose speed is thermostatically controlled. Also, a separate electric starter is not required, reducing the price, dimensions and weight of the entire device.

Namen in cilj izumaPurpose and object of the invention

S predstavljeno rešitvijo je mogoče z enim samim preprostim električnim strojem, v pričujočem primeru motorgeneratorjem, ki ne potrebuje vzdrževanja in v vrtečih delih nima navitij, generirati enosmerni električni tok konstantne napetosti in izmenični električni tok konstantne napetosti in frekvence za pokrivanje nepogonskih potreb motoriziranega sredstva. Po predlagani rešitvi je električni tok na voljo pri vseh vrtilnih frekvencah motorja. Poleg tega lahko navedeni motorgenerator zažene motor z notranjim zgorevanjem motoriziranega sredstva. Isti motorgenerator služi tudi kot električni pogon motoriziranega sredstva, odvisen od zmogljivosti akumulatorskih baterij. Motor z notranjim zgorevanjem lahko skupaj z motorgeneratorjem poganja motorizirano sredstvo in tako poveča naj večjo moč motorja z notranjim zgorevanjem, ali pa izboljša njegovo pospeševanje. S tem se znižajo stroški opreme, stroški vgradnje, vzdrževalni stroški in tudi teža same opreme. Vse našteto velja, ko primerjamo predlagano rešitev z vsemi znanimi ali na trgu prisotnimi rešitvami. Poleg tega pa v primeru nevarnosti laliko v trenutku in brez sunkov - samo z vklopom sklopke - preidemo iz načina pogona motoriziranega sredstva z elektromotorjem na zagon motorja z notranjim zgorevanjem. To tudi izboljša zanesljivost in varnost rešitve. Z vodotesno namestitvijo motorgeneratorja v hermetično zaprtem okrovu vztrajnika je dosežena najvišja raven zanesljivosti za motorizirana sredstva, ki se delno nahajajo v vodi, ali pa so izpostavljena vodnim pljuskom. Ker je z DC-AC inverterjem možno generirati izmenični električni tok konstantne napetosti in konstantne frekvence, je izmenični električni tokWith the present solution, it is possible to generate a direct current constant current and alternating current and frequency electrical current to cover the non-driven needs of the motorized means with a single simple electric machine, in this case a maintenance-free motor and no winding parts. According to the proposed solution, electrical current is available at all engine speeds. In addition, said motorgenerator may start an internal combustion engine of a motorized means. The same motorgenerator also serves as the electric drive of the motorized means, depending on the capacity of the rechargeable batteries. An internal combustion engine can, together with a motor generator, drive a motorized means to increase the internal combustion engine's power or to improve its acceleration. This reduces the cost of equipment, installation costs, maintenance costs and also the weight of the equipment itself. All of the above applies when comparing a proposed solution with all known or commercially available solutions. In addition, in an emergency, the laliko switches from instantaneous motorized drive mode to an internal combustion engine, with and without clutch only by switching on the clutch. This also improves the reliability and security of the solution. The watertight installation of the motor generator in a hermetically sealed flywheel housing achieves the highest level of reliability for motorized parts that are partly in the water or exposed to water splashes. Since DC-AC inverter can generate alternating current of constant voltage and constant frequency, alternating current is

-5na voljo tudi takrat, ko edini električni generator ne deluje in sicer z izrabljanjem zmogljivosti nadomestne akumulatorske baterije. Ko je potreben le del maksimalnega električnega toka, mora motor z notranjim zgorevanjem delovati le omejen čas in z zmanjšano vrtilno frekvenco.-5Available even when the sole electric generator does not operate by utilizing the capacity of a replacement battery. When only part of the maximum electric current is required, the internal combustion engine must only run for a limited time and with a reduced speed.

AC-DC usmernik 17 je povezan z enosmernim filtrom 18, ki visokofrekvenčnim motnjam, ki nastajajo v dodatnem DC-DC pretvorniku - napetostnem regulatorju 19, preprečuje dostop v statorska navitja 12 generatorja, kjer bi lahko povzročile porast temperature motorgeneratorja. DCDC pretvornik - napetostni regulator 19 dovaja potrebno enosmerno napetost sistemskemu izhodu, akumulatorskim baterijam 20 in DC-AC inverterju 31, ki je povezan z AC vhod-izhod spojnikom 32.

S pomočjo daljinskegaThe AC-DC rectifier 17 is coupled to a DC filter 18 that prevents high-frequency interference from the additional DC-DC converter - voltage regulator 19 from accessing the stator windings 12 of the generator, which could cause the generator to rise in temperature. DCDC Converter - Voltage Regulator 19 supplies the required DC voltage to the system output, rechargeable batteries 20, and DC-AC inverter 31, which is connected to the AC input-output connector 32. The output of the DC-DC switch 9 is controlled to match the battery voltage, condition its charge and battery charging characteristics. With the help of remote control

By means of cooling ducts 34, the engine generator is cooled sufficiently to achieve high output power with a watertight unit. At the same time, permanent magnets 26 of the rotor 3 from rare earths are protected from too high temperatures that could demagnetize them.
