Ruzivo rwekushanda kwemota yemabhurashi uye mota isina mabhurashi

Musimboti wekushanda kwemota yebhurashi

Chimiro chikuru chemota isina mabhurashiiri stator + rotor + bhurashi, uye torque inowanikwa nekutenderera simba remagineti kuti ribudise simba rekinetic. Bhurashi iri rinogara richibata necommutator kuti riite magetsi uye richinje chikamu mukutenderera.

Mota yebhurashi INOSHANDISA kuchinja kwemuchina, danda remagineti harifambi, kutenderera kwecoil. Kana mota ichishanda, coil necommutator zvinotenderera, ukuwo bhurashi remagineti nekabhoni hazvitenderere. Kuchinja kwekuchinjana kwegwara recoil current kunoitwa necommutator nebhurashi rinotenderera nemota.

Mumota yebhurashi, maitiro aya ndeekubatanidza magumo maviri esimba re coil, uye, akarongwa mu ring, akaparadzaniswa nezvinhu zvinodzivirira pakati peumwe neumwe, achigadzira cylinder yakaita se organic, inova chinhu chose che organic kakawanda ne motor shaft, simba rinobuda kuburikidza ne pillar mbiri diki dzakagadzirwa ne kabhoni (kabhoni bhurashi), pasi pesimba rechitubu, kubva panzvimbo mbiri dzakatarwa, kumanikidzwa kwesimba, mapoinzi maviri e circular cylindrical coil kusvika ku coil ye seti yemagetsi.

SezvomotaKana ichitenderera, ma coil akasiyana kana matanda akasiyana e coil imwe chete anosimbiswa panguva dzakasiyana, kuitira kuti pave nemusiyano wakakodzera weAngle pakati pe ns pole ye coil inogadzira magnetic field ne ns pole ye stator ye magnet stator iri pedyo. Magnetic fields inokwezvana uye inodzingana, ichigadzira simba uye ichisunda mota kuti itenderere. Carbon electrode inotsvedza pamusoro wewaya sebhurashi pamusoro pechinhu, saka zita rekuti "bhurashi".

Kutsvedza pamwe chete kunokonzera kukweshana uye kurasikirwa nemabhurashi ekabhoni, ayo anofanira kutsiviwa nguva nenguva. Kuchinjana pakati pebhurashi ekabhoni nemusoro wewaya wecoil kunogona kukonzera spark yemagetsi, kuputika kwemagetsi uye kukanganisa michina yemagetsi.

Musimboti wekushanda kwemota isina brushless

Mumota isina brushless, kuchinja kunoitwa nedunhu rekudzora riri mucontroller (kazhinji ke hall sensor + controller, uye tekinoroji yepamusoro ndeye magnetic encoder).

Mota isina mabhurashi INOSHANDISA electronic commutator, coil haifambi, magnetic pole inotenderera. Mota isina mabhurashi INOSHANDISA seti yemidziyo yemagetsi kuti inzwe nzvimbo yemagnetic pole yepermanent magnet kuburikidza ne hall element SS2712. Zvichienderana nepfungwa iyi, electronic circuit inoshandiswa kushandura direction ye current mu coil panguva yakakodzera kuti ive nechokwadi chekuti simba remagnetic rinogadzirwa munzira chaiyo yekutyaira mota. Bvisa zvakaipa zve brush motor.

Maseketi aya anonzi mamota controllers. Mutongi wemota isina brush anogonawo kuita mamwe mabasa asingakwanise kuitwa nemota isina brush, akadai sekugadzirisa Angle yekuchinja magetsi, mota yebhureki, kuita kuti mota idzokere shure, kukiya mota, uye kushandisa chiratidzo chebhureki kumisa magetsi kuenda kumota. Iye zvino bhatiri remota rava kukiya alarm yemagetsi, riri kushandiswa zvizere kwemabasa aya.

Mota yedc isina brushless imhando yemechatronics, inoumbwa nemuviri wemota nemutyairi. Sezvo mota yedc isina brushless ichishandiswa otomatiki, haizowedzera winding yekutanga kune rotor senge mota inochinjika ine variable frequency speed regulation uye heavy load start, uye haizokonzere kuzunguzika uye kubuda kana mutoro wachinja.

Musiyano wemodhi yekudzora kumhanya pakati pemota yemabhurashi nemota isina mabhurashi

Kutaura zvazviri, kutonga kwemhando mbiri dzemota kunodzora voltage, asi nekuti brushless dc INOSHANDISA electronic commutator, saka inogona kuwanikwa nekudzora kwedhijitari, uye brushless dc iri kuburikidza nekabhoni brush commutator, kushandisa silicon controlled traditional analog circuit kunogona kudzorwa, zviri nyore.

1. Maitiro ekudzora kumhanya kwemota yebhurashi ndeyekugadzirisa voltage yemagetsi emota. Mushure mekugadzirisa, voltage nemagetsi zvinoshandurwa necommutator nebhurashi kuti zvichinje simba remagnetic field rinogadzirwa neelectrode kuti zvizadzise chinangwa chekuchinja kumhanya. Maitiro aya anozivikanwa se pressure regulation.

2. Maitiro ekudzora kumhanya kwemota isina brushless ndeyekuti voltage yemagetsi emota inoramba isina kuchinja, chiratidzo chekudzora chekugadzirisa kwemagetsi chinochinjwa, uye mwero wekuchinja kwechubhu yeMOS ine simba guru unochinjwa ne microprocessor kuti ione shanduko yekumhanya. Maitiro aya anonzi frequency conversion.

Musiyano wekushanda

1. Mota yebhurashi ine chimiro chiri nyore, inokura kwenguva refu uye tekinoroji yakakura

Kare muzana remakore rechi19, mota iyi payakatanga kushandiswa, mota iyi yaive isina mabhurashi, kureva mota yeac squirrel-cage asynchronous, iyo yaishandiswa zvakanyanya mushure mekugadzirwa kwemagetsi anochinja-chinja. Zvisinei, mota iyi ine zvikanganiso zvakawanda zvisingakundike, zvekuti kuvandudzwa kwetekinoroji yemota kunononoka. Kunyanya, mota yedc isina mabhurashi haina kukwanisa kushandiswa mubhizinesi. Nekukura nekukurumidza kwetekinoroji yemagetsi, yave ichishandiswa zvishoma nezvishoma mubhizinesi kusvika makore achangopfuura. Muchidimbu, ichiri muboka remota yeac.

Mota isina brush yakazvarwa nguva pfupi yapfuura, vanhu vakagadzira mota isina brush dc. Nekuti mashandiro emota yedc brush ari nyore, ari nyore kugadzira nekugadzirisa, ari nyore kugadzirisa, ari nyore kudzora; mota yeDc ine mhinduro inokurumidza, torque hombe yekutanga, uye inogona kupa rated torque performance kubva pazero speed kusvika pakumhanya kwakayerwa, saka yave ichishandiswa zvakanyanya kana yabuda.

2. Mota yeDC isina brushless ine kumhanya kwekupindura nekukurumidza uye torque hombe yekutanga

Mota isina mabhurashi yeDc ine mhinduro yekukurumidzira kutanga, torque huru yekutanga, shanduko yekumhanya yakagadzikana, hapana kuzununguka kunonzwika kubva pazero kusvika pakumhanya kwakanyanya, uye inogona kutyaira mutoro mukuru kana yatanga. Mota isina mabhurashi ine resistance huru yekutanga (inductive reactance), saka simba remagetsi diki, torque yekutanga idiki, ruzha rwekutanga rwuri kurira, rwuchiperekedzwa nekuzununguka kwakasimba, uye mutoro wekutyaira mudiki kana yatanga.

3. Mota yeDC isina brushless inomhanya zvakanaka uye ine mhedzisiro yakanaka yekubhureka

Mota isina brush inodzorwa nemagetsi, saka kutanga nekubhuraki zvakagadzikana, uye kumhanya kunogara kuripo kwakagadzikanawo. Mota isina brush inowanzo dzorwa ne digital frequency conversion, iyo inotanga yachinja ac kuita dc, uye yozobva yachinja dc kuita ac, uye inodzora kumhanya kuburikidza nekuchinja kwema frequency. Saka, mota isina brush haifambi zvakanaka pakutanga nekubhuraki, ine vibration huru, uye inongogadzikana chete kana kumhanya kwacho kuripo.

4, kunyatsorongeka kwemota ye dc brush kwakakwira

Mota isina mabhurashi yeDc inowanzo shandiswa pamwe chete nebhokisi rekuderedza simba remota uye decoder kuti simba rekubuda kwemota rikure uye kunyatsogona kudzora kukwire, kunyatsogona kudzora kunogona kusvika 0.01 mm, kunogona kuita kuti zvikamu zvinofamba zvimire chero kupi zvako kwaunoda. Zvishandiso zvese zvemuchina wekugadzirisa zvine hungwaru hwekutonga kwemota yeDC. Sezvo mota isina mabhurashi isina kugadzikana panguva yekutanga uye yekubhureka, zvikamu zvinofamba zvinomira panzvimbo dzakasiyana nguva imwe neimwe, uye nzvimbo yaunoda inogona kumiswa chete nekuisa pini kana muganhu wenzvimbo.

5, mutengo wekushandisa mota yebhurashi yedc wakaderera, kugadzirisa kuri nyore

Nekuda kwechimiro chiri nyore chemota yebrushless dc, mutengo wakaderera wekugadzira, vagadziri vazhinji, tekinoroji yakakura, saka inoshandiswa zvakanyanya, senge mafekitori, maturusi emuchina wekugadzirisa, zvishandiso zvehunyanzvi, nezvimwewo, kana mota ikakundikana, ingotsiva bhurashi rekabhoni, bhurashi rega rega rekabhoni rinongoda madhora mashoma, zvakachipa zvikuru. Tekinoroji yemota isina brush haina kukura, mutengo wakakwira, chiyero chekushandisa chakaganhurirwa, kunyanya inofanira kunge iri mumidziyo yekumhanya nguva dzose, senge frequency conversion air conditioning, firiji, nezvimwewo, kukuvara kwemota isina brush kunogona kutsiviwa chete.

6, hapana bhurasho, kupindira kwakaderera

Mota dzisina mabhurashi dzinobvisa bhurashi, shanduko yakananga ndeyekusavapo kwemota yebhurashi inomhanya, nokudaro zvichideredza zvikuru kukanganiswa kwesimba remagetsi kumidziyo yeredhiyo iri kure.

7. Ruzha rwakaderera uye kushanda zvakanaka

Pasina mabhurashi, mota isina mabhurashi ichave nekukweshana kushoma panguva yekushanda, kushanda zvakanaka uye ruzha rwakaderera, izvo zvinotsigira zvikuru kugadzikana kwekushanda kwemodheru.

8. Hupenyu hwebasa refu uye mutengo wakaderera wekugadzirisa

Kusashandisa mabhurashi zvakanyanya, kusashanda zvakanaka kwemota isina mabhurashi kunonyanya kuitika mubearing, kubva pakuona kwemuchina, mota isina mabhurashi inenge iri mota isina kugadziriswa, kana zvichidikanwa, ingogadzirisa guruva.
