Kwemakore akati wandei, tanga tichiona motoro emagetsi tanga kutonga zvishandiso zvisina mwero mutyairi mune indasitiri yehunyanzvi. Izvi zvakanaka, asi chii chikuru chibvumirano? Zvakakosha here chero bedzi ini ndichigona kutyaira iyo yehuni screw? um, hongu. Kune mutsauko wakakosha uye mhedzisiro kana uchibata nemutori wakasungwa uye motorsless motors.
Tisati tasvetuka mumatombo maviri-tsoka uye nebrush motors, ngatitangei tinonzwisisa ruzivo rwechokwadi rweiyo dc motors. Kana zvasvika pakutyaira motors, zvese zvinoenderana nemagineti. Yakatarisana nemagineti akapomerwa mhosva. Pfungwa yekutanga yeDCM mota ndeyekuti uchengetedze iyo inopesana neyemagetsi chikamu chechikamu chekutenderera Izvo zvishoma sekuisa bestton butter donut pane tsvimbo pamberi pangu pandinomhanya-ini ndicharamba ndichiedza kuzviita!
Mubvunzo ndewekuti ungachengeta sei donuts. Iko hakuna nzira iri nyore yekuzviita. Inotanga ine seti yemagineti isingaperi (magneti zvachose). Seti yeElectromagns inoshandura shanduko (kudzoreredza polarity) pavanotenderera, saka pane nguva dzose mageti isingagumi neyekupesana nemhosva inogona kufamba. Uye zvakare, iyo yekuraira yakafanana inosangana neiyo Electromagnetic coil sezvazvinoshanduka ichasundira iyo coil kure. Patinotarisa motorsed motors uye motorsless motors, maitiro eElectromnet inochinja porsity ndiyo kiyi.
Mumotokari yakasviba, pane zvikamu zvina zvakakosha: magneti zvachose, miganhu, kufambidzana nemhete uye brushes. Iyo isingagumi maget inoita kunze kwekunze kwemuchina uye haina kufamba (stator). Imwe inobhadharwa zvakanaka uye imwe inobhadharwa zvakanaka, ichigadzira nzvimbo isingaperi yemagineti.
Iyo Armature iri coil kana nhevedzano yemaroji ayo anova electromagnet kana akasimbisa. Izvi zvekare chikamu chinotenderera (rotor), chinowanzogadzirwa nemhangura, asi aluminium inogona kushandiswawo.
Mhete yeCommutator inogadziriswa kune iyo Armature Coil mune maviri (2-pole inogadziriswa), mana (4-pole inogadziriswa) kana zvimwe zvikamu. Vanotenderera neiyo armature. Pakupedzisira, mabhureki emakaroni anogara ari munzvimbo uye aendese mhosva kune mumwe nemumwe Commutator.
Kamwe chete iyo Armature iri simba, iyo coil yakaipomerwa ichadhonzwa yakananga kune yakasarudzika inobhadharwa yakaipomerwa simba. Kana murume weCommutator pamusoro payo anotenderera, inofamba kubva kune yekubatanidza kweimwe kabhoni brashi kune inotevera. Kana ichisvika rinotevera brashi, ichagamuchira kudzokerera kwehupombwe uye iko zvino kwave kufarirwa neimwe nzvimbo yechigarire paunenge uchidzingirirwa nemhando imwechete yemagetsi. Angaita kuti, kana munhu wekumanikidza anosvika kune yakaipa bhurashi, yava kukwezva nemagineti isingaperi. Muperekedzi anosvika panguva yekuumba kubatana neakanaka elektrode brashi uye kutevera kune yakaipa nzvimbo isingaperi. Iwo mabhureki ari maviri, saka iyo coil yakanaka ichadhonza yakananga kumagineti isina kunaka, uye iyo coil yakaipa ichadhonza kune iyo yakanaka magineti panguva imwe chete.
Zvakafanana neni ndiri learrey coil ichidzingirira botson butter donut. Ndakaswedera, asi ndakachinja pfungwa dzangu uye ndikadzingirira munhu ane hutano (polarity yangu kana chishuwo chakachinja). Mushure mezvose, donuts dzakapfuma mumakarori uye mafuta. Iye zvino ndiri kudzingira svutugadzike ndichisundidzirwa kubva kuBoston cream. Pandakasvika ikoko, ndakaona kuti donuts iri nani pane kusemesa. Chero bedzi ini ndichidhonza iyo trigger, pese pandinoenda kune inotevera burashi, ini ndichashandura pfungwa dzangu uye panguva imwe chete kudzingirira zvinhu zvandiri kudengenyeka. Iyo ndiyo yekupedzisira application yeADHD. Uyezve, kune vaviri vedu ipapo, saka Boston butter donuts uye masoice anogara achikurudzirwa nemufaro neumwe wedu, asi kusava nehanya.
Mumotokari yebrashless, iwe unorasikirwa nemutengesi uye brushes uye uwane controller yemagetsi. Iyo isingagumi Magnet ikozvino serinotenderera uye inotenderera mukati, nepo mutambi arehwa neyekunze yakatarwa extromagnetic coil. Anopokana anopa simba kune imwe neimwe kiroti kubva pane zvekupomera zvaidikanwa kuti ukwezve magineti isingaperi.
Pamusoro pekupomerwa mhosva yemagetsi zvemagetsi, mutongi anogona zvakare kupawo mhosva yakafanana yekupikisa magneti zvachose. Sezvo mhosva yemhando imwechete yakatarisana nedzimwe, izvi zvinosundidzira magineti isingaperi. Iye zvino rotor inofamba nekuda kwekudhonza uye kusundira mauto.
Mune ino kesi, magneti zvachose anogara achifamba, saka ikozvino ivo vanomhanya neni neni. Hatichinje pfungwa yezvatinoda. Panzvimbo pezvo, taiziva kuti ndaida Boston butter donuts, uye mumwe wangu aida kusemerwa.
Vatambi vemagetsi vanobvumira zvido zvedu zvekudya kwekudya kwekudya kwemangwanani edu kuti vatamire pamberi pedu, uye tanga tichitevera zvinhu zvakafanana nguva dzese. Iye anotonga zvakare anoisa zvinhu zvatisingade kuti ape kusundira.
Bhurawu Dc motors idzo dzakareruka uye dzakachipa kuti dzigadzire zvikamu (kunyangwe ndarira harisati rakachipa). Sezvo mota yebrashi inoda mutauri wemagetsi, iwe uri kutanga kuvaka kombiyuta mune chombo chisina tambo. Ichi ndicho chikonzero chekusundira mutengo werudzi rusina motors.
Nekuda kwekugadzira zvikonzero, brush motors ine zvakawanda zvakanakira pamusoro pevhu zvakaburitswa. Vazhinji vavo vane hukama nekurasikirwa kwemakwenzi nevatambi. Sezvo brashi inoda kusangana neanomutamura kuti aendese mhosva, inokonzerawo kukakavara. Kukakavara kunodzora kumhanya kunogoneka uye panguva imwe chete kunogadzira kupisa. Zvakafanana nekutasva bhasikoro nemabhureki emwenje. Kana makumbo ako akashandisa iyo simba rimwe chete, kumhanya kwako kuchadzikira. Zvekare, kana iwe uchida kuchengetedza kumhanya, iwe unofanirwa kuwana simba rakawanda kubva pamakumbo ako. Iwe zvakare uchapisa iyo rims nekuda kwekupisa kupisa. Izvi zvinoreva kuti, kana zvichienzaniswa nevatori vebushe, motorsless motors inomhanya pane yekudziya yakadzika. Izvi zvinovapa zvakanyanya kugona, saka ivo vanoshandura mamwe emagetsi simba kuita simba remagetsi.
Karbhoni brushes ichapfekedza zvakare nekufamba kwenguva. Izvi ndizvo zvinokonzeresa spark mukati meimwe maturusi. Kuti chengetedza chishandiso chinomhanya, brashi inofanira kutsiviwa nguva nenguva. Brushless motors haidi rudzi urwu rwekuchengetedza.
Kunyangwe hazvo motors isina bhuroka ichida zvemagetsi zvemagetsi, iyo rotor / stator musanganiswa wakaenzana. Izvi zvinotungamira kumikana yekuyera uremu uye kuwedzera saizi. Ndokusaka tichiona zvakawanda zvishandiso zvakaita saMakita XDT16 Driver Driver neAltra-Compact Designs uye Simba Rine Simba.
Iko kunoratidzika kunge kusanzwisisana nezve brushless motors ne torque. Bhururuka kana brushless mota dhizaini pachayo hainyatsoratidza hukuru hwe torque. Semuenzaniso, iyo torque chaiyo yemurume wekutanga Milwaukee M18 Fuel Hammer Drill yaive diki pane iyo yapfuura yakasungwa mhando.
Nekudaro, pakupedzisira Mugadziri akaziva zvimwe zvinhu zvinonyanya kutsoropodza. Magetsi anoshandiswa mune brushless motors anogona kupa simba rakawanda kune aya motors kana zvichidikanwa.
Sezvo burlush motors ikozvino ishandise kudzora kwepamhepo zvemagetsi, vanogona kuona kana vatanga kuyananisa pasi pemutoro. Chero bedzi bhatiri uye mota zviri mukati meiyo tembiricha yehurongwa, iyo maruva emotokari emagetsi anogona kukumbira uye kugamuchira mari yazvino kubva pabhatiri pack. Izvi zvinobvumira maturusi akadai sekurova kusingafadzi uye saws kuchengetedza yakakwirira kumhanya pasi pemutoro. Izvi zvinovaita nekukurumidza. Zvinowanzoitika nekukurumidza. Mimwe mienzaniso yeiyi inosanganisira Milwaukee Redlink Plus, Makita LXT mukana uye dewalt ita uye chengetedza.
Iyi matekinhini seumableyly batanidza motors yezvishandiso, mabhatiri, uye zvemagetsi kuita system yekubatanidza kuti izadzise kuita uye runtime.
Commitation-shandura logyity yekubhadhara-kutanga mota yebrashless uye ichiramba ichitenderera. Tevere, iwe unofanirwa kudzora kumhanya ne torque. Iko kumhanya kunogona kudzorwa nekuchinja iyo voltage yeBLDC mota stator. Kutenderedza voltage pane yakakwira frequency inobvumira kuti udzore motokari kumhanya kune yakakura degree.
Kuti udzore torque, apo iyo torque mutoro wemotokari inomuka pamusoro peimwe nhanho, iwe unogona kuderedza voltage voltage. Ehe, izvi zvinosuma zvakakosha zvinodiwa: mota yekutarisa uye sensors.
