Brush mota inoshanda musimboti
Chimiro chikuru chebrushless motais stator + rotor + bhurashi, uye torque inowanikwa nekutenderedza magineti kuti ibudise kinetic simba.Bhurashi rinogara richisangana necommutator kuitisa magetsi uye kushandura chikamu mukutenderera.
Brush mota SHANDISA mechanical commutation, magineti pole haifambi, coil rotation.Kana mota ichishanda, coil necommutator zvinotenderera, ukuwo magineti simbi nekabhoni brashi zvisingaite.Iko kuchinjika shanduko yekoil ikozvino kutungamira kunopedzwa nemufambi uye bhurashi inotenderera nemota.
Mune bhurashi mota, iyi maitiro ndeyekuunganidza iwo maviri emagetsi ekuisa ekupedzisira ecoil, zvakare, akarongwa mumhete, akapatsanurwa nezvinhu zvekudzivirira pakati peumwe neumwe, kugadzira chero senge cylinder, kuita organic yakazara kakawanda nemota shaft. , simba rekupa kuburikidza nembiru mbiri diki dzakagadzirwa nekabhoni (kabhoni bhurashi), pasi pechiito chekumanikidza kwechirimo, kubva kune maviri chaiwo chinzvimbo chakamisikidzwa, kudzvanywa kwemagetsi ekuisa, mapoinzi maviri edenderedzwa cylindrical coil kune coil yeseti ye magetsi.
Sezvomotainotenderera, macoil akasiyana kana mapango akasiyana ekoiri imwe chete anopihwa simba panguva dzakasiyana, kuitira kuti pave neakakodzera Angle musiyano pakati pe ns danda rekoiri inogadzira magineti uye ns danda repedyo rekusingaperi magineti stator.Magnetic fields anokwezvana uye anodzingana, achigadzira simba uye kusunda mota kuti itenderere.Kabhoni electrode inotsvedza pamusoro wewaya sebhurasho riri pamusoro pechinhu, nekudaro zita rekuti "bhurashi".
Kutsvedza kune mumwe nemumwe kunokonzeresa kukweshera uye kurasikirwa kwekabhoni mabhurashi, ayo anoda kuchinjwa nguva nenguva.Kuchinjana nekudzima pakati pekabhoni brashi nemusoro wewaya wekoiri kunogona kukonzera spark yemagetsi, kuputika kwemagetsi uye kukanganisa midziyo yemagetsi.
Brushless mota inoshanda musimboti
Mune brashiless mota, iko kuchinjika kunoitwa neyekudzora wedunhu mu controller (kazhinji horo sensor + controller, uye yakawedzera tekinoroji ndeyemagnetic encoder).
Brushless mota INOSHANDISA electronic commutator, coil haifambi, magineti pole inotenderera.Brushless mota INOSHANDISA seti yemidziyo yemagetsi kunzwa pamire magnetic pole yemagineti inogara kuburikidza nehoro element SS2712.Zvinoenderana nepfungwa iyi, dunhu remagetsi rinoshandiswa kushandura mafambiro echizvino mucoil panguva yakakodzera kuti ive nechokwadi chekugadzirwa kwesimba remagineti munzira kwayo kutyaira mota. Bvisa zvipingamupinyi zvebhurashi mota.
Aya maseketi anonzi mota controllers.Mutongi weiyo brushless mota anogona zvakare kuona mamwe mabasa asingagone kuitwa neiyo brushless mota, sekugadzirisa magetsi ekuchinja Angle, braking mota, kuita kuti mota idzokere kumashure, kukiya mota, uye kushandisa bhureki chiratidzo chekumisa simba rekupa kune mota.Zvino bhatiri mota yemagetsi alarm lock, pakushandiswa kwakazara kweaya mabasa.
Brushless dc mota ndeye yakajairwa mechatronics chigadzirwa, inoumbwa nemota muviri uye mutyairi.Sezvo brushless dc mota ichishandiswa mune otomatiki control mode, haizo wedzera mhepo yekutenderera kune rotor senge mota inopindirana ine inosiyana frequency kumhanyisa mutemo. uye mutoro unorema unotanga, uye hauzokonzerese oscillation uye kubuda kunze kana mutoro wachinja.
Musiyano wekumhanyisa kudzora modhi pakati pebhurashi mota uye brushless mota
Muchokwadi, kutonga kwemhando mbiri dzemota ndeye voltage regulation, asi nekuti brushless dc INOSHANDISA yemagetsi commutator, saka inogona kuwanikwa nedhijitari control, uye brushless dc iri kuburikidza nekabhoni brashi commutator, uchishandisa silicon inodzorwa yechinyakare analog wedunhu inogona kudzorwa. , zviri nyore.
1. Iyo yekumhanyisa regulation process yebrashi mota ndeye kugadzirisa voltage yemagetsi ekupa mota.Mushure mekugadzirisa, voltage uye ikozvino inoshandurwa ne commutator uye brashi kuti ichinje simba remagineti inogadzirwa ne electrode kuti iwane chinangwa chekuchinja kukurumidza.Iyi nzira inozivikanwa sekumanikidza mutemo.
2. Iyo yekumhanyisa kudzora maitiro eiyo brushless mota ndeyekuti vhezheni yemagetsi emagetsi emagetsi anoramba asina kuchinjika, chiratidzo chekudzora chekugadzirisa magetsi chinoshandurwa, uye chiyero chekuchinja chepamusoro-simba MOS chubhu inoshandurwa ne microprocessor kuti ziva kushanduka kwekukurumidza.Iyi nzira inonzi frequency conversion.
Musiyano wekuita
1. Brush mota ine chimiro chakareruka, nguva yakareba yekuvandudza uye tekinoroji yakakura
Kare muzana remakore rechi19, apo motokari yakazvarwa, injini inoshanda yaiva brushless fomu, iyo inonzi ac squirrel-cage asynchronous motor, iyo yakashandiswa zvakanyanya mushure mekugadzirwa kwealternating current.Zvisinei, asynchronous motor ine zvakawanda zvisingagoneki kukanganisa, saka kuti kuvandudzwa kwemichina yemotokari kunonoka.Kunyanya, brushless dc motor haina kukwanisa kuiswa mukushanda kwekutengeserana.Nekukurumidza kukurumidza kwehunyanzvi hwemagetsi, yakaiswa zvishoma nezvishoma mukushanda kwekutengeserana kusvika makore achangopfuura.Muchidimbu, ichiri chikamu cheiyo ac mota.
Brushless mota yakazvarwa nguva pfupi yadarika, vanhu vakagadzira iyo brushless dc mota.Nekuti iyo dc brush mota meshini iri nyore, iri nyore kugadzira uye kugadzirisa, iri nyore kuchengetedza, iri nyore kudzora;Dc mota ine zvakare mhinduro inokurumidza, hombe yekutanga torque, uye inogona kupa yakatemerwa torque kuita kubva zero kumhanya kusvika yakayerwa kumhanya, saka yakashandiswa zvakanyanya kana yangobuda.
2. Iyo brushless dc mota ine kukurumidza kupindura kumhanya uye hombe yekutanga torque
Dc brushless mota ine kukurumidza kutanga mhinduro, hombe yekutanga torque, yakagadzikana kukurumidza shanduko, inenge isina vibration inonzwika kubva zero kusvika pakumhanya kwakanyanya, uye inogona kutyaira yakakura mutoro paunotanga. simba chinhu idiki, torque yekutanga idiki, ruzha rwekutanga rwuri kurira, runoperekedzwa nekuzunguza kwakasimba, uye mutoro wekutyaira mudiki paunotanga.
3. Iyo brushless dc mota inomhanya zvakanaka uye ine yakanaka braking effect
Iyo brushless mota inodzorwa nevoltage regulation, saka iyo yekutanga uye braking yakagadzikana, uye inogara ichimhanyisa mashandiro zvakare yakagadzikana.Brushless mota inowanzodzorwa nedhijitari frequency kutendeuka, iyo inotanga kuchinja ac ku dc, uyezve dc ku ac, uye inodzora kumhanya kuburikidza nekuchinja kwe frequency.Naizvozvo, iyo brushless mota haifambi zvakanaka kana ichitanga uye ichibhureki, ine vibration yakakura, uye inongogadzikana kana kumhanya kunogara.
4, dc bhurashi mota yekudzora kurongeka kwakakwira
Dc brushless mota inowanzo shandiswa pamwe chete nedecoder box uye decoder kuita kuti simba rekubuda remota rive rakakura uye kutonga kwakaringana kwakakwira, kurongeka kwekutonga kunogona kusvika 0.01 mm, kuda kuregedza zvikamu zvinofamba zvimire pane chero nzvimbo yaunoda. maturusi ari dc motor control accuracy.Sezvo iyo brushless mota isina kugadzikana panguva yekutanga uye braking, zvikamu zvinofamba zvichamira panzvimbo dzakasiyana nguva imwe neimwe, uye chinzvimbo chinodiwa chinogona kungomiswa nekuisa pini kana chinzvimbo chinomisikidza.
5, dc brashi mota yekushandisa mutengo yakaderera, kugadzirisa kuri nyore
Nekuda kwechimiro chakareruka chebrushless dc mota, mutengo wakaderera wekugadzira, vagadziri vazhinji, tekinoroji yakakura, saka inoshandiswa zvakanyanya, senge mafekitori, maturusi emuchina wekugadzira, midziyo chaiyo, nezvimwe, kana mota yatadza, ingotsiva kabhoni brashi. , imwe neimwe kabhoni brashi inongoda madhora mashoma, yakachipa kwazvo.Brushless mota tekinoroji haina kukura, mutengo wakakwira, chiyero chekushandisa chinogumira, kunyanya chinofanira kunge chiri mumichina yekumhanyisa nguva dzose, senge frequency conversion air conditioning, firiji, nezvimwe. , brushless motor damage inogona kungotsiviwa.
6, hapana brashi, kupindira kwakaderera
Mabhurashi asina mota anobvisa bhurashi, shanduko yakananga kusavapo kwebhurashi mota inomhanya spark, nekudaro ichideredza zvakanyanya kukanganiswa kwemagetsi kumagetsi eredhiyo.
7. Mutsindo wakaderera uye kushanda zvakanaka
Pasina mabhurashi, mota isina mabhurashi ichava nekukwesha kwakawanda panguva yekushanda, kushanda kwakatsetseka uye kuderera kwakanyanya ruzha, inova rutsigiro rwakakura rwekugadzikana kwemuenzaniso wekushanda.
8. Hupenyu hurefu hwebasa uye mutengo wakaderera wekugadzirisa
Brush shoma, brushless mota inopfeka inonyanya kubereka, kubva pamichina yekuona, brushless mota ingangoita mota isina kugadzirisa, kana zvichidikanwa, ingoita imwe guruva kugadzirisa.
