A brushless mota imota yemagetsi isingashandisi mabhurashi. Iko kuchinjika kwebhurashi mota inoitwa zvemagetsi pachinzvimbo chekushandisa mabhurashi emuviri.
Izvi zvinoita kuti injini ishande uye inogara kwenguva refu. Brushless motors anoshandiswa mune akasiyana maapplication, anosanganisira mafani emakombuta, hard drive, uye mota dzemagetsi.
Ivo zvakare vanowanzoshandiswa mupamusoro-kuita zvishandiso zvemagetsi.
Mune ino posvo isu tichafukidza:
Ndezvipi zvakanakira brushless motors?
Brushless motors ine akati wandei mabhenefiti pamusoro pemabhurashi mota, zvinosanganisira kugona kwepamusoro, kuderera kwemagetsi kukanganiswa, uye hupenyu hurefu. Brushless motors zvakare idiki uye yakareruka pane yakabhurwa mota.
Ndezvipi zvisingabatsiri zve brushless motors?
Imwe yezvakanyanya kuipa kwebrashiless motors ndeyekuti inodhura kupfuura mabhurashi mota. Brushless motors inodawo mamwe akaomarara emagetsi controller, achiaita atonyanya kudhura.
Iwo Intricacies eBrushless Motors: Kunyatsotarisa
Brushless motors imhando yemagetsi emagetsi anoshandisa magineti kuburitsa kutenderera kwekufamba. Izvo zvikamu zviviri zvikuru zvebrashiless mota ndiyo stator uye rotor. Iyo stator inhengo yakamira iyo ine kutenderera kwemota, nepo rotor iri chikamu chinotenderera chine magineti asingagumi. Kudyidzana pakati pezvikamu zviviri izvi kunogadzira kutenderera kwemota.
Basa remaSensors muBrushless Motors
Brushless mota dzinovimba nema sensors kuona nzvimbo ye rotor uye kufambisa mota. Mhando dzakajairika dzemasensor anoshandiswa mumabhurashi motors iholo sensors, inductive sensors, uye zvinogadzirisa. Aya ma sensors anopa mhinduro kune yemagetsi control system, ichiibvumira kugadzirisa kumhanya uye kutungamira kwemota sezvinodiwa.
Izvo Zvakanakira zveBrushless Motors
Brushless mota dzinopa akati wandei mabhenefiti pamusoro pechinyakare brushed DC mota, kusanganisira:
- Kubudirira kwepamusoro

- Zvido zvekuchengetedza zvakaderera
- Kushanda kwakadzikama
Brushless Motors: Inoshandiswa kupi?
Brushless motors anowanzo shandiswa mune cordless magetsi maturusi nekuda kwekuita kwavo kwakanyanya uye kushomeka kwekugadzirisa zvinodiwa. Zvishandiso izvi zvinosanganisira zvibhorani, masaha, uye kukanganisa vatyairi izvo zvinoda yakakwirira torsion kubuda uye kudzora kumhanya kwakatsetseka. Brushless motors inokwanisa kupa iyi inobuda uku ichichengetedza diki uye hupenyu hurefu hwebhatiri kana uchienzaniswa nemabhurashi mota.
Zvigadzirwa zvemagetsi
Brushless motors anoshandiswawo muhuwandu hwemidziyo yemagetsi, senge mafeni uye hard disk drive. Iyo yakaderera ruzha uye chaiyo yekumhanyisa kudzora kwebrushless mota inoita kuti ive yakakodzera kune aya maapplication. Pamusoro pezvo, kushaikwa kwemabhurashi kunoreva kuti hapana chikonzero chekugara uchigadzirisa, zvichikonzera hupenyu hurefu hwechigadzirwa.
ZveMotokari Maindasitiri
Brushless mota dziri kutanga kutonga indasitiri yemotokari nekuda kwekugona kwavo kuita nemazvo uye kutonga. Iwo anowanzo shandiswa mumotokari dzemagetsi nekuda kwekuita kwavo kwepamusoro uye kugona kuchengetedza chaiyo kumhanya. Pamusoro pezvo, kushaikwa kwemabhurashi kunoreva kuti hapana chikonzero chekuwedzera zvikamu kana kubatanidza, zvichikonzera dhizaini iri nyore uye yakavimbika.
Computer Kutonhodza Systems
Brushless motors anowanzo shandiswa mumakomputa ekutonhodza masisitimu nekuda kwekugona kwawo kuchengetedza kumhanyisa kumhanya uye kubuda. Iyo electromagnetic dhizaini yemabhurashi motors inobvumira mutsara wekumhanya-torque hukama, zvichikonzera kushanda kwakatsetseka uye kwakanaka. Pamusoro pezvo, saizi diki yemabhurashi motors inobvumira huwandu hwakakura hwemashandisirwo muzvikamu zvekombuta.
Indasitiri yeAerospace
Brushless motors anoshandiswawo muindasitiri yeaerospace kune yavo yakakwirira simba kubuda uye kugona kuchengetedza chaiyo kumhanya. Iwo anowanzoshandiswa muhurongwa hwekudzora ndege uye giya rekumhara nekuda kwekuvimbika kwavo uye nemazvo. Uyezve, kushayikwa kwemabhurashi kunoreva kuti hapana chikonzero chekugadzirisa nguva dzose, zvichiita kuti hupenyu hurefu hwezvikamu.
Kutsvaga nekuvandudza
Brushless motors anoshandiswawo mukutsvagisa uye kusimudzira kugona kwavo kupa yakakwira mwero wekurongeka uye kutonga. Iwo anowanzo shandiswa mukuyedza michina uye zviridzwa zverabhoritari zvinoda chaiyo kumhanya uye kubuda. Pamusoro pezvo, kushaikwa kwemabhurashi kunoreva kuti hapana chikonzero chekugadzirisa nguva dzose, zvichikonzera hupenyu hurefu hwemidziyo.
Kuongorora Akasiyana-siyana Ekuvaka Tekinoroji eBrushless Motors
Imwe yemhando dzinowanzozivikanwa dzebrashiless mota ndiyo inogara magineti mota. Muchivakwa ichi, rotor inoumbwa nemagineti echigarire anotenderedza iyo yemagetsi armature. Iyo stator, kune rumwe rutivi, ine nhevedzano yematanda anokuvadzwa nemakoiri. Kana simba remagetsi richipfuura nemakoiri, magnetic field inogadzirwa, zvichiita kuti rotor ichinje.
Advantages:

Brushless Vs Brushed DC Motors: Ndeipi Misiyano Yakakosha?
Brushless uye brushed DC mota dzinosiyana mukugadzira uye kuvaka. Brushed DC motors ine rotor, stator, uye commutator, nepo brushless DC motors ine rotor ine magineti asingagumi uye stator ine windings. Iyo commutator mumabhurashi mota ine basa rekuchinja polarity ye electromagnet, nepo mumabhurashi motors, iyo polarity yewaya windings inongochinja nemagetsi.
Kudzora Techniques uye Input Simba
Brushless mota dzinoda dzakaomarara kudzora maitiro kupfuura mabhurashi mota. Vanoda yakakwira yekupinza voltage uye yazvino, uye maseketi avo ekutonga anowanzo kuumbwa nemaseti matatu ewaya, imwe neimwe yakamira 120 madhigirii. Mabhurashi mota, kune rumwe rutivi, inongoda waya imwe chete kuti ichinje kuchengetedza iyo inotenderera yemagineti.
Performance uye Hupenyu hwose
Brushless motors ine yakakwira simba-ku-huremu reshiyo uye inowanzo shanda kupfuura mabhurashi mota. Ivo zvakare vane hupenyu hurefu nekuda kwekushaikwa kwemabhurashi anosakara nekufamba kwenguva. Brushless motors inokwanisa kupa kuita zvirinani uye kugona kwesimba, zvichiita kuti ive sarudzo iri nani kune yakakwirira-kuita maapplication.
Acoustic Noise uye Electromagnetic Kupindira
Brushless motors inoburitsa ruzha rushoma pane mabhurashi mota nekuda kwekushaikwa kwemabhurashi. Ivo zvakare vanogadzira kushomeka kwemagetsi kupindira, zvichiita kuti ive sarudzo iri nani yezvishandiso zvinoda ruzha rwakaderera uye kushomeka kwemagetsi kukanganiswa.
Kusarudza Pakati peBrushless uye Brushed DC Motors
Pakusarudza pakati pe brushless uye brushed DC motors, pane akati wandei akakosha zvinhu zvekufunga nezvazvo:
- Simba rekushandisa rinoda
- Kushanda kunodiwa uye kubudirira
- Iyo acoustic ruzha uye electromagnetic kupindira zvinodiwa
- Hupenyu uye kuchengetedza zvinodiwa
Zvichienderana nezvinhu izvi, munhu anogona kusarudza kushandisa brushless kana brushed DC mota. Brushless motors anowanzo kukodzera zvirinani kune yakakwirira-kuita maapplication ayo anoda hukuru hwesimba uye yakaderera acoustic ruzha, nepo mabhurashi mota akakodzera zvirinani kune madiki, akaderera-simba maapplication anongoda yakakosha mota.
mhedziso
Saka, mabhurashi mota inzira huru yekuwana zvakanyanya kubva pachigadzirwa chako pasina dambudziko rekubata nemabhurashi. Anoshanda zvakanyanya, akanyarara, uye ane hupenyu hurefu kupfuura mabhurashi mota. Uyezve, anoshandiswa mumidziyo yakawanda yakasiyana ikozvino, kubva kune maturusi emagetsi kuenda kumotokari dzemagetsi. Saka, kana iwe uchitsvaga mota nyowani, iwe unofanirwa kufunga nezve brushless mota. Ndivo ramangwana remotor, shure kwezvose. Saka, usatya kunyura mukati uye vaedze. Iwe haunganyadziswi!
Ini ndini Joost Nusselder, muvambi weZvishandiso Chiremba, mushambadzi wemukati, uye baba. Ini ndinoda kuyedza michina mitsva, uye pamwe nechikwata changu ndanga ndichigadzira zvakadzama blog zvinyorwa kubva 2016 kubatsira vaverengi vakavimbika nematurusi & matipi ekugadzira.
