Izifunda kanye Nezinhlelo Zokuqala

Ukuze umshini wesigaba esisodwa usebenze, kufanele kukhunjulwe ukuthi kukhona okuhambisanayo kokuphepha kwesekethe, isibonelo salokhu kungaba: i-omnipolar magneto-thermal lever kanye nokunye. ukudluliselwa okunesikhathi izinsalela ezikwazi ukuvimbela ukushisisa okuningi kwenjini.

Imizila yama-motor yenziwe ngezixhumi zomfutho nokulawula kwe-motor, ama-motor circuits ahlukaniswe kabili, i-force noma i-power circuit kanye nomyalo kanye ne-signal circuit. Lesi sakamuva saziwa nangokuthi isizinda.

Kumjikelezo wokulawula, amazinga aphansi emisinga nama-voltage (amasignali) asetshenziswa ngaphezu kwanoma yini enye ngamandla noma amandla ngokuphambene, ngalawa mazinga aphezulu emisinga nama-voltage alawulwa.

Amasekhethi okulawula namasignali asebenzisa izimpawu ezihambisana nemiyalo yokulawula yamakhoyili, izilawuli nezinye izinto eziphathwayo ngogesi. Lokhu kumelela indlela yomsebenzi ekufakeni noma ekuzisebenzeleni.

Siyini isivinini salezi zinjini?

Uma unokuqhubeka okukhulu kwe-alternating current izoba nesivinini esingcono, uma unenombolo enkulu yezigxobo izoba nejubane eliphansi, ngale ndlela umshini onesivinini esiphezulu yilowo onama-poles angu-2.

Ezwekazini laseYurophu ukuqhubeka kokunikezwa kwesigaba esisodwa kungu-40 Hz (hertz) kuyilapho eMelika kungu-70 Hz.

Isivinini esijwayelekile salezi zinjini ku-60Hz siyahluka phakathi kuka-1.400 rpm no-4000 rpm, konke kuncike ekutheni une-pole motor engu-2 noma 4, kukhona ama-voltages ajwayelekile angu-250 V phakathi kwesigaba nokungathathi hlangothi.

Lolu hlobo lwejubane lwaziwa ngokuthi i-synchronism, lokhu kusho ukuthi yinkundla ejikelezayo ye-stator, ngenxa yalokhu ijubane langempela le-rotor lincane kakhulu, lawa ama-asynchronous motors futhi kukhona ukushelela okubangelwa umthwalo olahlekile, ngaphezulu noma ngaphansi kwalokho bekungaba ngu-5%.

Kungani isivinini sincike enanini lezigxobo?

Ukuqala injini yezigxobo ezi-2, lapho ibona umjikelezo wengxenye yamanje eshintshashintshayo, yenza ukuheha okubenza bajike ukuze bavale sonke isikhala esigcwaliswa isigxobo esisodwa, ngesikhathi lapho kuvela enye ingxenye yomjikelezo, izokwenza. hamba enye isigxobo, ngaleyo ndlela uqedele ukujika okuphelele kumjikelezo ngamunye

Uma i-alternating current iyimijikelezo engama-60 ngomzuzwana, injini izonikeza okungenani ukuzungezisa okungu-70 ngomzuzwana (ukuzungeza okungu-4000 ngomzuzu), enenjini engu-6-pole enomjikelezo owodwa, ikwazi ukunikeza isigamu ukujika, ngoba izigxobo izothatha ingxenye yesithupha ye-stator, ezodinga imijikelezo engu-6 uhhafu ukuze iqedele ukuzungezisa okukodwa okugcwele.

Kungani bengaqali bodwa?

Uma umjikelezo kagesi wesigaba esisodwa ubekwa futhi wethulwa ku-voltage eshintshanayo, inkambu yokulutha efinyelelwayo iwumkhakha ohlukile ozinzile, lokhu kusho ukuthi yonke impahla yengqamuzana iyashintsha ngokuqhubekayo ngokushintshana, okukhuphuka futhi kwehle nge-polarity ngayinye ngendlela efanayo. indlela eya kumfutho wamanje oshintshanayo.

Konke lokhu kwenziwa ku-eksisi yakhona ngakho akuyona inkambu ejikelezayo ye-hypnotic.

Le nkambu ye-stator ixhunywe esigabeni esingakhethi (isigaba esisodwa), noma ingaguquki, lapho yonke imigqa yayo yensimu inqanyuliwe, izinduku ze-rotor zikhiqiza amandla kagesi aqhutshwa kuzo, okuthi, ngokuba ku-current-circuit currents. zakhiwe ezindongeni ze-rotor ngakho-ke zibangela insimu yamagnetic ezungezile ngamandla afanayo ku-rotor.

Ukuphazamiseka kwenzeka lapho lezi zipheya zamandla zisendleleni eyodwa kanti enye ingxenye ibheke ngakolunye uhlangothi (lapho i-current in the stator ihluka nge-polarity), ngaleyo ndlela ivimbele ukujikeleza kwe-rotor. Ayiqukethe i-duet yokuqala njengoba amapheya womabili ayasuswa.

Ngaphansi kwalezi zimo, uma i-rotor iphushwa ngesandla kwenye yezindlela ezimbili, kungenzeka ukuhlanganisa i-axis ye-rotor magnetic field kuleso siqondiso, i-motor izoqala ukujikeleza ngokwayo ize ifinyelele isivinini sayo sokuzisholo. I-motor izobe ijikela ohlangothini olufanayo nasekuqaleni kuze kube yilapho amandla esuswa.

Indlela yokubona i-axiliary winding eyinhloko?

Lokhu kulula kakhulu njengoba uma amatheminali amabili noma izintambo zinokuphikisana ziyisekethe kagesi, ngokuba nenye yalezi ezimbili uzokwazi ukuthi iyiphi enokumelana okuphezulu, uma kunjalo iyona eyinhloko, kuyilapho enye izoba esikhundleni. , kufanele uhlale ukhumbula lapho kukhona Izingozi Ugesi njengoba ngesikhathi sokuxhumana nogesi akunakugwemeka ukuthi lezi zivele.

UMichael Faraday wayaziwa ngokuba ngumdali we-electrochemistry kanye ne-electromagnetism.

Ngonyaka we-1821 ngemva kokwembulwa kwemodeli kazibuthe yisazi sesayensi yemvelo saseDenmark uHans Christian Ørsted, uDavy kanye nososayensi waseBrithani uWilliam Hyde Wollaston banquma ukugxila ekusebenzeni kwenjini okwaba ukukhungatheka okuphelele.

UFaraday, ngemva kokucabanga ngale nkinga ngala madoda amabili, wema waqina, waqhubeka esebenza emgomweni wakhe, futhi wakwazi ukwenza izinto ezimbili azibiza ngokuthi "i-electromagnetic rotation". Enye yalezi manje ibizwa ngokuthi i-homopolar motor.

Imishini eyinhloko kwakuyizinto zikagesi ezilula, lezi zazisetshenziselwa ukwenza izivivinyo ezihlukahlukene ezenziwa indela yaseScottish Benedictine u-Andrew Gordon kanye nomdali waseMelika uBenjamin Franklin ngonyaka we-1740.

Ukuqala kwabo kwembulwa yiNgisi uHenry Cavendish e, nakuba kungazange kuvele, lesi simo sasungulwa ngumFulentshi uCharles-Augustin de Coulomb e, owasenza saziwe.
