AC: Scheme. Iimoto zombane kunye AC

Kweli nqaku uza kufunda izinto zombane AC, cinga isixhobo zabo, isimiso ukusebenza, ummandla isicelo. Kufuneka kuqatshelwe ukuba namhlanje kushishino ngaphezu kwama-95 ekhulwini zonke iinjini ezisetyenziswayo accounted for koomatshini emgudu munye. Baye bafumana kwande ngenxa yokuba ukuba ukuthembeka phezulu, zinokuba elide kakhulu ngenxa maintainability yayo.

Ummiselo okusebenzela yoqheliso iinjini

Ukuze siqonde indlela injini, uyakwazi ukuqhuba eksperimenti kancinane. Kakade ke, kuya kufuneka ukuba ube isixhobo okhethekileyo. Faka i umazibuthe xa elimile intsimbi yehashe kangangokuba owamiselwa isiphatho ihamba. Njengoko usazi, kwimagnethi uye izibonda ezimbini. Phakathi kwabo kuyimfuneko ukuba amalungiselelo akwitankana ezenziwe ngobhedu. Ngendlela yokuba ngokukhululekileyo jikeleza ngeenxa axis yayo. Ngoku nokuhlola ngokwayo. Qala ukujija umazibuthe, oku kudala ntsimi enambuzelayo. Ngaphakathi lombhobho ubhedu aqale kuvela imisinga eddy, leyo simelane umazibuthe endle.

Ngenxa yoko, itankana sobhedu uqalisa ukujikeleza indlela apho ihamba umazibuthe osisigxina. Ngaphezu koko, akukho isantya thile ezisezantsi. Isizathu soku - ngesantya esifanayo njengoko imigca ukhozo force ukuphazamisa kwimagnethi endle. Lo mhlaba otsalayo ujikeleza synchronously. Kodwa ke isantya intshukumo kwimagnethi Nonsynchronous. Ke ukuba inkcazelo cut kancinane, emgudu munye. Ngenxa yoko igama umatshini yombane - motor kuFacebook. Ukuba rough, isiphaluka AC ngeemoto malunga ziyafana kungentla nokuhlola. Kuphela lo mhlaba otsalayo okudalwe stator jiko.

DC motor

Ahluke kancinane i-AC Motors induction. Okokuqala, kukho umntu stator elinye okanye amabini jiko. Okwesibini, indlela yokutshintsha isantya plane thile ezahlukeneyo. Kodwa plane ujikelezo ulwalathiso Ukuguqulwa utshintsho wokwephuka (in koomatshini olungenangqamaniso-mbane iindawo isigaba utshintsho). Tshintsha isantya i-DC-mafutha plane kunokwenzeka, ukuba ukwanda okanye ukuhla i ombane anikiwe stator emajikojiko.

DC motor akakwazi ukusebenza ngaphandle excitation jiko, nto leyo ukwakweli ivili. Le ombane transfer kwenzeka ngokusebenzisa ibandla brush. Le yeyona ongathembekanga loyilo. Iibhrashi elenziwe grafayithi, ekugqibeleni wasuswa, phambili ukusilela injini, kuyimfuneko ukulungisa. Qaphela ukuba AC and DC Iimoto zombane kufuneka izinto ezifanayo, kodwa nezakhiwo zawo zahluke kakhulu.

Uyilo injini yombane

Njengaye nawuphi na umatshini non-emile yombane, i-injini olungenangqamaniso inamacandelo amabini eziphambili - le stator kunye ivili. Into yokuqala zesigxina ezikuwo wabeka engathi ezintathu ezidibene ngokomfuziselo ethile. Le plane ezinokususwa, uyilo ebizwa ngokuba "unomatse ebuhlanti". Isizathu sokuba eli gama kukuba isakhiwo lwangaphakathi efana kakhulu ivili kunye nomatse.

Le yokugqibela, Kakade, hayi enjinini. egxile kwi plane yenziweyo ezimbini ziquka, zixhonywe stator. Bona iibheringi eziququzelela ujikelezo. Ngasemva le impeller motor efakiweyo. Ngenxa yalo isisiza, pholisa ikhutshwa phandle kumatshini. Stator udale umfazi ngolo bambo, ngakumbi ubushushu transfer. Ngaloo iinjini AC ezisebenza nolawulo thermal eqhelekileyo.

Le stator i motor induction

Kufuneka kuqatshelwe ukuba izibonda stator yeemowutha olungenangqamaniso mihla engavezwanga. Ngamafutshane, lonke ngaphakathi komhlaba ngokupheleleyo egudileyo. Ukwenzela ukunciphisa ilahleko eddy lwangoku, umongo iqokelelwe zizixwexwe kakhulu ngentsimbi. Ezi kwiimakhishithi kakhulu olusondeleyo ukuqhagamshelana nabanye yaye kamva engatshintsiyo kwizindlu ezenziwe ngentsimbi. Le stator iye vee ngenxa ekubekeni engathi.

Le engathi enziwe wire yobhedu. Idibanisa kubo ngendlela "inkwenkwezi" okanye "unxantathu". Kwinxalenye engentla umzimba ikhaka encinane, bodwa ngokupheleleyo. Kukho abafowunelwa kunye nonxibelelwano loqhakamshelwano le engathi. Kwaye ungakwazi ukudibanisa ukusongwa usebenzisa Jumpers ezifakwe kwi kwiqela lenjongo. Le fowuni i motor AC yenza uxhulumaniso ekhawulezayo le engathi kwi pattern oyifunayo.

Rotor kuFacebook motor

Ngaye ke kuthiwa kancinane kakhulu. Unjani ehokweni nomatse. Uyilo plane ibandla ukusuka zizixwexwe intsimbi, kwakunye stator. Le Slots plane lizoqala, kodwa kunokuba ube iintlobo ezininzi. konke kuxhomekeke ekubeni okanye kwisigaba unomatse-ebuhlanti ivili. Zoyilo zixhaphakileyo zakutshanje. iintonga copper ashinyeneyo ibekwa vee ngaphandle izinto zokwambathisa ezikhoyo. On zombini iziphelo kweentonga ezidibene amakhonkco zobhedu. Ngamanye amaxesha, endaweni "nomatse ebuhlanti" rotors ingxubevange kusetyenziswa.

Kodwa kusekho Motors AC kunye Motors slip-ring. Zisetyenziswa kakhulu ngaphantsi ngokufuthi, ikakhulu ngenxa Iimoto zombane, leyo babe namandla eliphezulu kakhulu. Ityala yesibini, apho kuyimfuneko ukuba kusetyenziswe Motors slip-ikhonkco Iimoto zombane - nokudalwa eninzi umgudu ngexesha sokuqaliswa. Noko ke, kuba oku kuyimfuneko ukuba basebenzisa okhethekileyo rheostat.

Iindlela uqale kuFacebook motor

Run AC motor olungenangqamaniso ilula, nje kufuneka ukudibanisa engathi stator inethiwekhi ontlantlu-ntathu. Uxhulumaniso lusenziwa ngoncedo contactors ngemagnethi. Enkosi kubo, ungenza phantse imishini isiqalo. Nditsho reverse kunokwenziwa ngaphandle kobunzima kakhulu. Kodwa kwezinye iimeko kuyimfuneko ukunciphisa ombane ukuba lusetyenziswa engathi stator.

Oku kwenziwa ngokusebenzisa imizobo Uxhulumaniso "unxantathu". Kulo start-up xa engathi lidibane i "inkwenkwezi". Ngenxa yokwanda isantya, yokufikelela kwimfuno ukutshintshela "ogudle" wesiphaluka ubuninzi jiko. Ngoko ke, kukho ukwehla kweyangoku konga malunga emithathu amaxesha. Kodwa uyazi ukuba asizizo zonke stator unako ukusebenza ngokufanelekileyo xa uqhagamshele ngokungqinelana dweliso 'unxantathu ".

zokulawula isantya

Kushishino kunye nobomi bemihla ngemihla babe converters rhoqo kuthandwa. Ngenxa uncedo, bangaba Betha izihlahla ukuba tshintsho ojikeleza isantya ivili. Kufuneka kuqatshelwe ukuba AC Motors zisetyenziswa kunye inverters rhoqo kwizinto ezininzi. It ikuvumela ukuba ulungise kakuhle urhwebo ngaphakathi drive, akukho mfuneko yokuba ukusetyenziswa magnetic actuators. Zonke ulawulo uqhagamshele iterminal njalo inverter. Izicwangciso kuzakuvumela utshintshe ngexesha yokunyusa mafutha plane, isingxi, lo gama i-minimum and esiphezulu isantya, kwakunye nezinye protective imisebenzi.

isiphelo

Ngoku uyazi indlela umsebenzi motor AC. Nkqu uyilo ithandwayo wafundela le motor induction. Yeyona ntaka yonke, leyo thaca kwi emarikeni. Ukongeza, kuba eqhelekileyo umsebenzi akukho mfuneko ukusebenzisa eyahlukileyo abangabancedani izixhobo. Ingakumbi, le dimmers. Kwaye kuphela Ukongeza enjalo, njengoko amaza lokuguqulela, enokwenza kube lula ukusebenza motor induction, ukwandisa kakhulu izakhono zalo.
