Xa uyila kwaye ukhethaimpompo yamanzi encinci, i-drive motor yeyona nto ibalulekileyo ekumiseleni ukusebenza, ubomi benkonzo kunye nexabiso lepompo. Ngokwesiqhelo, amacala amabini ale duel aqhelekile.iimoto zebrashi yekhabhonikwayeiimoto zanamhlanje ezingenabhrashiFunda umahluko obalulekileyo ekukhetheni ipompo efanelekileyo kwiprojekthi yakho.

Okokuqala, mandicacise ingcamango

Oko sikubiza ngokuba yi-"carbon brush motor" kunye ne-"brush motor" kwicandelo leempompo zamanzi ezincinci kubhekisa kuhlobo olufanayo lwemoto -- i-DC brush motor, esebenzisa ibrashi yekhabhoni (ibrashi) ukuqhagamshelana ne-commutator ukuze iqondise umbane kwaye itshintshe indlela eya ngayo intsimi yemagnethi.
Kwaye abachasi bayo, kungenxa yokutshintsha kwesekethe ye-elektronikii-motor ye-dc engenabhrashiulawulo.

Ukuze siqonde ngcono umahluko wabo ophambili, singenza uthelekiso olukhawulezileyo ngokujonga le theyibhile ilandelayo:

1. Imoto yebhrashi yekhabhoni: ukhetho oluqhelekileyo nolungabizi kakhulu

 

Iimoto zebhrashi yekhabhoni, ezaziwa ngokuba ziimoto zeDC ezibhrashiweyo, zizisombululo zokuqhuba ezivuthiweyo kakhulu ngobuchwephesha.

Umgaqo Wokusebenza
Ingundoqo idlula ezimbiniiibhrashi zekhabhoni(yenziwe ngegrafiti nesinyithi) njengezixhobo zoqhagamshelwano ezizinzileyo, ezinokujikelezaiphepha lokuhambakwi-motor rotor contact contact eqhubekayo, ukuze icala langoku lihlale litshintsha, ukuze i-rotor iqhubeke ijikeleza.

Ezona mpawu:

1 Iingenelo:

Ixabiso Eliphantsi: Ulwakhiwo olulula, iteknoloji evuthiweyo, iindleko zokuvelisa ziphantsi kakhulu kunemoto engenamabhrashi, nto leyo eyenza ixabiso lepompo lonke likhuphisane kakhulu.

 

Ulawulo Olulula：Isantya kunye ne-torque zinokulungiswa ngokulula ngokutshintsha i-voltage okanye i-current, njengokusebenzisa ulawulo lwesantya se-PWM olula, ngaphandle kwesidingo seesekethe zokuqhuba ezintsonkothileyo.

2.UbubiUbomi obulinganiselweyo: Le yeyona ntsilelo inkulu yemoto yebhrashi yekhabhoni. Ibhrashi yekhabhoni iyasetyenziswa kwaye iya kuguga kancinci kancinci ngexesha lokungqubana okukhawulezayo kwexesha elide ne-commutator. Xa igugile, imoto iya kungasebenzi. Ke ngoko, ubomi beemoto zebhrashi yekhabhoni buhlala buqala kumakhulu aliqela ukuya kumawaka aliqela eeyure.

3. Kuya kubakho ukuphazamiseka kwe-electromagnetic:Ibhrashi yekhabhoni kunye ne-commutator ziya kuvelisa iintlantsi zombane ngexesha lokudibana nokwahlukana, nto leyo eya kubangela ukuphazamiseka kwe-electromagnetic kwizixhobo ze-elektroniki ezingqongileyo.

4.Ukusebenza kakuhle okuphantsi kakhulu:Ngenxa yokuxhathisa ukungqubana kunye nokuxhathisa ukudibana kwebrashi yekhabhoni, ukulahleka kwamandla kukhulu, kwaye ukusebenza kakuhle kuhlala kuphantsi kunokweemoto ezingenamabhrashi.

5. Ingxolo:Ukungqubana kwebrashi yekhabhoni kunye nentlantsi kuya kuvelisa ingxolo ethile yokusebenza.

2-Injini engenabhrashi: ukhetho lwanamhlanje lokusebenza okuphezulu

Injini engenabhrashiimele ulwalathiso lobuchwepheshe oluphucukileyo nolusebenzayo.

Umgaqo Wokusebenza：
Iyayicima intsebenziswano yomzimba phakathi kwebrashi yekhabhoni kunye ne-commutator. Endaweni yoko,isilawuli se-elektronikiisetyenziselwa ukuqonda indawo yerotor kunye nokulawula ngokuchanekileyo ulandelelwano lokunika amandla kunye nexesha lee-stator coils, ngaloo ndlela iqhuba irotor ukuba ijikeleze. Oku kukuguquka "kwe-elektroniki" kunokuba "kukuguqulwa" koomatshini.

Uphawu oluPhambili：

Iingenelo：

Ubomi obude：Ngenxa yokuba akukho zixhobo zokunxibelelana zomzimba ekufuneka zinxitywe, ubomi bayo buxhomekeke kuphela ekugugeni kwebheri, ngokuqhelekileyo ukuya kuthi ga kumashumi amawaka eeyure, nto leyo ephindaphinda kalishumi okanye kalishumi ubomi bemoto yebhrashi yekhabhoni.

Ukusebenza kakuhle, ukusetyenziswa kwamandla aphantsi：Akukho lahleko yokunxibelelana koomatshini kwaye ukusebenza kakuhle kokuguqulwa kwamandla kuphezulu, oko kuthetha ukuba konga umbane omninzi okanye kunokubonelela ngemveliso enkulu ngamandla afanayo.

Ilizwi eliphantsi：Akukho ngxolo yokungqubana kwebhrashi yekhabhoni, ukuze usebenze ngokuthula ngakumbi.

Akukho kuphazamiseka kwe-electromagnetic:Akukho ngxaki ye-EDM, inobuhlobo kakhulu kwiinkqubo ze-elektroniki ezibuthathaka.

Ulawulo oluphezulu:Xa idityaniswe nomlawuli okrelekrele, inokufezekisa imisebenzi ephambili efana nolawulo lwesantya oluchanekileyo, ukhuseleko lwe-rotor olutshixiweyo, kunye nokukhupha isignali yempendulo.

Iingxaki:

Ixabiso eliphezulu:Ulwakhiwo lwemoto kunye nomlawuli wedrive ofunekayo zintsonkothile ngakumbi kunezo zeemoto zebrashi yekhabhoni, nto leyo ebangela iindleko eziphezulu.

Ulawulo oluntsonkothileyo:Kufuneka ixhomekeke kumlawuli ozinikeleyo ukuze isebenze kwaye ayinakujikeleza ngokuthe ngqo xa ivuliwe njengenjini yebrashi yekhabhoni.

Khetha ipompo "yemoto engenabhrashi" xa:

Ukuthembeka kunye nobomi obude zezona mfuno ziphambili.Izixhobo kufuneka zisebenze ngokuzinzileyo ixesha elide. Zisetyenziswa kwiindawo ezibuthathakaukuphazamiseka kwe-electromagnetic, njengezixhobo zonyango, izixhobo zelebhu, kufutshane neenkqubo zesandi ze-hi-fi. Kufunekaukusebenza kwengxolo ephantsi, njengezixhobo zasekhaya, ii-aquarium ezithuleyo, izixhobo zeofisi. Ukusebenza kakuhle kwamandla kuyafuneka, ingakumbi kwizixhobo eziphathwayo ezisebenza ngebhetri.Ulawulo olukrelekrelekuyimfuneko, njengokunxibelelana neekhompyutha ezincinci ezine-single-chip kunye nolawulo oluchanekileyo lokuhamba kombane, njl.

Izicelo eziqhelekileyo:izixhobo zokuxilonga zonyango, oomatshini bekofu, izicoci zamanzi eziphezulu, izixhobo ze-elektroniki zeemoto, iimpompo zokujikeleza amanzi e-aquarium ezihlala ixesha elide, iinkqubo zokutshiza izithuthi ezingenamntu, njl.

isishwankathelo

Ngamafutshane, ukhetho lwemoto yebhrashi yekhabhoni kunye nemoto engenabhrashi ngaphakathi impompo ye-diaphragm encincingokusisiseko kukuthengiselana phakathi"ixabiso" kunye "nokusebenza".

Iimoto zebrashi yekhabhoni, ngenxa yenzuzo yazo enkulu yeendleko kunye nolawulo olulula, zisenesikhundla esibalulekileyo kwimarike ejongene namaxabiso.

Injini engenabhrashingayoukuthembeka okugqwesileyo, ubomi obude kunye nokusebenza okugqwesileyo okubanzi,iye yaba yeyona nto iphambili kwiizicelo zanamhlanje ezikumgangatho ophezulu nezifunwa kakhulu. Ndiyathemba ukuba eli nqaku liza kukunceda wenze ukhetho lobuchwepheshe olunolwazi oluphezulu.
