Ruzivo rwepamota rwakazara nenhau kune brushless motors

Mumamiriro ezvinhu akajairika, maererano nerudzi rwekushanda kwemagetsi: inogona kukamurwa mukatiDcm mota uyeAC mota. DC Motors inogona kukamurwa mukati brushless DC yemagetsi mota uye brashi dc motors maererano nechimiro chavo uye musimboti wekushanda. Mupfungwa yakatetepa: brushless mota inoreva mota isina brashi uye mutengesi (kana muunganidzi rombo), zvakare anozivikanwa semota yekutonga. Mune imwe pfungwa yakafara: ese motorsless motors ari motors asingafadzi.

Pakutanga kwekuzvarwa kwemota muzana ramakore rechi 19, mota inoshanda yakagadzirwa ifomu rakasviba, kureva kuti ac squirrel cage motor asynchronous, iyo yakashandiswa zvakanyanya. Nekudaro, asynchronous motors ane hurema hwakawanda husina kuremara, zvekuti kukura kwemotokari kunononoka. Iyo turberistor yakazvarwa pakati pezana remakore rapfuura, saka iyo motoro eDC yekushandisa uchishandisa commutor circuitator mudunhu panzvimbo yebrashi uye mutengesi akauya. Iyi mitsva yebhuruu isina bhurashi inonzi yakasarudzika zvemagetsi inosangana neDc mota, iyo inokurira zvikanganiso zvechizvarwa chekutanga chegwenzi remagetsi.

Brushless DC mota: Verenga zvinyorwa zvakawanda uye kusarudzika sumo, brushless DC mota uye brush Inosanganisirwa muzvinyorwa zvakawanda brushless dc mota uye dc brushless mota zvakare yakanyanya kuvhiringidzika, zvinenge zviripo chete. Naizvozvo, mupfungwa yakafara, brushless DC mota, brush Asi kubva pane yakatetepa yekutarisa mota, brush Izvo zvakaenzana nedzoroshi yakaiswa motoro dc muchimiro, Armature yayo yakaiswa patehwe, uye iyo rotor iri gwara risingaperi. Mhepo yayo yakarongedzwa iri polyphase mhepo, kazhinji matatu - Phase, inogona kubatana mune nyeredzi kana pembera. Chikamu chega chega chivharo chakabatana chakabatana chine transistor switch mune iyo yemagetsi colctator circutator circuit.

Yakapfupikiswa (BLDCM) - mhando yemotokari synchronous. . Brushless DC mota inogona kukamurwa mu brushless mhanyisa mota uye brushless torque mota. Muzhinji, mota yebrash isina brush Dzimwe nguva iyo yekutanga inonzi dc brushless mota (musimboti, iyo trapezoidal wave voltage ndeyekuverenga, AC Servico Motor (Kuti uve chaiwo, irwo rudzi rwe ac servo mota.)

Kuti udzikise nguva ye inertia, brushless dc motors inowanzo tora "slender" chimiro. Iyo brushless dc mota idiki kwazvo muhuremu uye vhoriyamu kupfuura iyo brasle dc mota, uye nguva inoenderana yeInertia inogona kuderedzwa ne40% - 50%. Nekuda kwezvinetso zvekugadzirisa zvezvinhu zvisingagumi zvemagroemesi, brush

Mota iyi ine mutsara wehunyanzvi hwehunyanzvi uye maitiro ekugadzirisa, hupenyu hwakawanda hwekumhanya, hupenyu hwakareba, uye hapana mota ine mari yekunyora, saka iyi mota inoshandisa yakakwana mukudzora masisitimu ekutonga.

Iyo Stator Withing yeMota inonyanya kugadzirwa nevatatu - Phase Symmetrical Star Convert, iyo yakafanana neiyo vatatu - phase asynchronous mota (iwe unogona kuona iyo yekubatanidza, zvakare inozivikanwa seInduction Motor). Magnetised zvachose magnet inosungirirwa kune iyo rotor yemota, uye sensor sensor yakaiswa mumota kuti uone polarm yeiyo rotor. Mutyairi anoumbwa nemidziyo yemagetsi nemagetsi uye zvapera. Chinzvimbo chesental chiratidzo uye chakashata uye chisina kunaka kushandura chiratidzo chinogamuchirwa kudzora iyo - kubva pane yega yega simba tube yeiyo inopinda bhiriji yekugadzira torque; Gamuchira mirayiridzo yekumhanyisa uye nekumhanyisa mhinduro dzemasaini kudzora uye kugadzirisa kumhanya; Ipa dziviriro uye kuratidza uye zvimwe.

Nekuti iyo motoro eDc inoshanda ne otomatiki control, haizofaniriwo mota inowirirana inotanga kutendeuka mhanya, uye haigone kutanga ichishandisa nzira mbiri dzekuenderana kutanga uye asynchronous anotanga. Synchronous Kutanga ndeyekunyora iyo synchronous mota kumunamati ebetsamba, batanidza iyo Simba Simba panguva imwe chete yekufananidza, uye kudhonza mune yakatarwa rotor magineti magineti. Iyi nzira yekutanga yakanyanya kuomesa uye isingawanzo kushandiswa mukuita. Kutanga kwekutanga ndeyepfupi - Dunhu reMotor Rotor kuwirirana, kana kumhanya kuri pedyo nekuwedzera simba panguva imwe chete, uye wozodhonza iyo yakatarwa rotor magineti mune inoenderana. Nekuda kwenhamba yekutendeuka kweMhepo Inonakidza, mhepo inonakidza inocheka munda wekutenderera uye inoburitsa voltage yakakwira kana mutoro unorema watangwa, izvo zviri nyore kuputsa mhepo uye kukonzera kushamisika kwemagetsi. In this way, the additional starting winding on the rotor will not cause oscillation and out-of-step when the load changes.

Nekuti iyo brush isc Iko kushanda kwekushanda, kuderera kweTorque torque, kumhanya kurongeka uye nekukasira uye nekukasira kwegwenzi dc mota dziri nani pane chero tekinoroji yekudzora, saka yakakodzera kutarisisa yeindasitiri. Ichi chigadzirwa chakagadzirwa250W BLDC Motorsto20KW BLDC motas, iyo inogona kugadzirisa izvo zvinodiwa kuchengetedza simba uye yakakwira - performance drive muindasitiri.
