Izibonelo - lapho motor kagesi isetshenziswa. Ukusetshenziswa kwama-motor kagesi

Motor oguqula amandla kagesi zibe amandla lokukhanda. Siqukethe stator (noma amahange) kanye Rotor. idivayisi okunjalo lithole yande kakhulu zonke izici zokuphila. Ngenxa motors kagesi kungase kuthathelwe indawo ezindaweni eziningi abantu umsebenzi umshini zabasebenzi. izinhlobo ezahlukene izinjini futhi uthole ukuthi zisetshenziselwa motors kagesi (bheka izibonelo. Ngezansi).

Umgomo we operation

I motor kagesi impela nje isebenza. Kusekelwe isimiso lokungeniswa kagesi. Ukufakwa kuhlanganisa ingxenye engaguquki - a stator aboshelwe AC motors kanye nohlobo zokuvumelanisa noma indlela inductor (DC motor), kanye Rotor, okusho ukuthi ingxenye ezithathekayo sezinhlobo zokuvumelanisa iphinde indlela, futhi amahange amadivayisi DC.

Rotors kungaba sesiwancamulile (squirrel yezinyoni uhlobo) kanye isigaba emazombezombe (ukushelela indandatho uhlelo). Ezimweni lapho uhlobo yokugcina motor isetshenziswa, kukhona indlela uhlobo idivayisi ukwehlisa komgomo womthetho okhona kanye nesivinini.

Ingxenye ezithathekayo zedivayisi DC noma yokusebenza ngalendlela ibizwa ngokuthi jikelele motor armature. motor Universal - nenjini DC kokuba ezilandelanayo ukushukuma isb uchungechunge uxhumano kanye armature emazombezombe. Reactance DC asipheli. Ngakho-ke, ngokususa iyunithi kagesi grinder, uzoqhubeka ukusebenza, ikakhulukazi uma amapayipi voltage ongaphakeme zamanje esetshenziswa - njalo.

kushintshana motors zamanje

Lezi units AC futhi DC. Kuzo zonke izindawo lapho motor kagesi isetshenziswa, ngokuvamile it has AC. Lokhu motor has a ukusebenza isimiso elula futhi kulula ukusebenza. Okuwukuphela ethile okuphawulekayo isivinini engalawuliwe.

motors kagesi kungase kube AC neqembu elilodwa noma ngaphezulu izigaba. Amadivayisi, okubhekisele AC motor, yilezo izimoto ukuthi akudingeki ukuba ulungise isivinini. Bangase babe ukufeza izinhloso ezehlukene (Mills, amaphampu umshini amathuluzi ukhuni ukusebenza, nokunye). ukujiya wabo phakathi ezimbili futhi eziyishumi ukuze amabili namashumi kilowatts ngenhla.

DC motors

Electric DC motors kungase kudingeke, kanye serial parallel okuxubile lemagalagala stator armature Windings. Inzuzo yabo ukuthi N ekubukekeni kwangaphambilini: ikhono esheshisa umthethonqubo. Nokho, ukusebenza kudinga ukusetshenziswa amandla.

Lezi motors kukhona brushless futhi ngalendoda.

Brushless noma valve - izinjini ezisebenza uhlelo ovaliwe inzwa okuyinto kuthola isikhundla Rotor futhi uhlelo lokulawula.

Commutator izinjini kungaba self-ujabule (okufanayo, serial noma okuxubile) kanye excitation ezimele.

Amadivayisi, lapho izinjini DC esetshenzisiwe, isibonelo, izimoto kagesi nemishini ehlukahlukene ukwakhiwa.

ukubukwa indlela

Elivame ukusetshenziswa kakhulu ezintathu okhombisa squirrel yezinyoni lokungeniswa motor. Kulokhu, lo ujikelezisa kazibuthe lingena Rotor sesiwancamulile emazombezombe, ngenxa lapho lokungeniswa zamanje kwenzeka. Ibizwa ngokuthi indlela ngoba ukujikeleza Rotor akulingani ukujikeleza stator kazibuthe.

Ukusetshenziswa kwama-motor indlela uthayiphe ezivamile amagatsha amaningi umkhakha, e zasendlini (amafriji, imishini yokuwasha, umoya isimo), kule mboni, ezifana izinkuni nensimbi, kanye ukwelukwa. Basebenza ukuzinza yezinye izinhlobo, kukhona engabizi futhi kulula ukusebenza.

buka kanyekanye

Evumelanisiwe motor Rotor ine design esihle, lapho le ngxenye imelelwa uzibuthe kagesi noma unomphela. Ukujikeleza imvamisa kulokhu kuvumelana stator kazibuthe Rotor imvamisa.

Lolu hlobo motors kagesi ingasetshenziswa uzotshala iziteshi, uma kudingeka esisheshayo amandla isinxephezelo, futhi kwamanye amacala.

Amafomu nesenzakalo torque

By endleleni kukhona torque motors kagesi zihlukaniswe hysteresis futhi magneto.

Okuvame kakhulu ezimbonini zendabuko zisebenzisa motors magnetoelectric hlobo. Kungenzeka njalo, futhi kushintshana zamanje. motors jikelele futhi akhona.

Kodwa umkhakha, lapho esetshenziswa motors kagesi kuthiwa, hysteresis, akakwazi ngokuthi ezivamile. Ngokuvamile, lezi amadivayisi ababezibheka embonini kuyaqabukela asetshenziswa. Iningi lazo asetshenziswa gyroscopes, esiphikisayo isikhathi, kanye idivayisi ukuqoshwa kwezwi nesithombe.

motors Universal ngalendoda uhlobo

Lapho isicelo kagesi jikelele ngalendoda uhlobo? Ngaphandle kwawo, tingasebenti le ezimbonini kanye izinto zasendlini, njengalowo oboniswa abalandeli, juicers, inyama grinders, vacuum cleaner omkhathi, amafriji kanye nokunye okufana nalokho. Basebenza bese uxhuma DC amandla ngesikhathi neshumi futhi volts amabili namashumi amabili, futhi AC 127 kanye 220 volts.

I-apharathasi izinjini like okuguquguqukayo DC motors kokuba ukuyaluza kuyavumelana.

Lapha waqoqa hhayi kuphela isisekelo kagesi steel ishidi uhlobo, kodwa la mandla, futhi ngokuqinisekile ijoka, kuyingxenye esimisiwe izintambo kazibuthe.

izinkampani I excitation kungenzeka uxhumekile nenye ohlangothini armature. Lokhu kunciphisa ukuphazamiseka ezakhiwe zomshini. Ijubane lokukhanya alishintshi futhi uhlale nalapho i zamanje kushintshana kufezwa ngokusebenzisa ukuqaliswa emkhakheni emazombezombe nge ompompi. Umehluko nje itholakala lokuthi ukuthi isetshenziswa ngokuphelele ngesikhathi inethiwekhi DC kanye AC - kancane kuphela.

Torque etholwe wamanje ukusabela ne magnetic field yokucucuza.

motors okunjalo nomthamo ingqikithi Watts emihlanu kuya angamakhulu ayisithupha (kodwa kwezinye izimo, isib, emithethweni kagesi, ukufinyelela Watts eyisishiyagalombili), futhi imvamisa ukujikeleza kusukela linemibhikisho yizinkulungwane ezimbili namakhulu ayisikhombisa namashumi ayisikhombisa nesishiyagalombili ngomzuzu. Kusukela lwamanje inrush incane, futhi ekuqaleni-up of ukumelana akudingeki. Inombolo ubuncane izikhonkwane abathelisi jikelele - ezine. Ababili babo zisetshenziselwa ukuxhuma DC ugesi, kanye nabanye ababili - I-AC. Kulo mBhalo, nekusebenta motor zizoba ngaphansi ngenxa okusezingeni eliphezulu ukulahlekelwa kagesi kazibuthe. AC Uzodla ngaphezu njalo, ngoba ingxenye esebenzayo hhayi kuphela, kodwa futhi esisheshayo.

ijubane ukujikeleza zingalawulwa, isibonelo, i-transformer othomathikhi noma rheostat.

Ngokushesha ukuthola indlela afanele

Kuyacaca ukuthi ziningi izindawo lapho motor kagesi isetshenziswa.

195 3730.12.40 - eziningana Ngokwesibonelo zokukhomba indlela, kanye lingakanani.

Ngenxa yokuthi i-onobuhle ezinkulu eziningi zalezi amadivaysi, futhi ezihlukahlukene osayizi namasimu ukusetshenziswa, udinga ukuthola kunzima kakhulu. Lokhu kuhlukaniswa lula kakhulu inqubo yokuthola efanelekayo motor kagesi.
