Isakhiwo esiyisisekelo se-induction motor:
1. Isakhiwo esiyisisekelo se-single-phase motor asynchronous
I-asynchronous motor enesigaba esisodwa iyinjini edinga kuphela ukunikezwa kwamandla kwe-AC kwesigaba esisodwa. I-asynchronous motor yesigaba esisodwa iqukethe i-stator, i-rotor, i-bearing, i-casing, ikhava yokugcina, njll. Umnyombo wensimbi wenziwe ngamashidi ensimbi e-silicon abhontshiwe futhi afakwe emseleni. Amasethi amabili ama-winding amakhulu (aphinde abizwe ngokuthi ama-winding agijimayo) kanye nama-winding asizayo (okubuye abizwe ngokuthi ama-winding okuqalisa akha ama-winding asizayo) ahlukaniswe ngo-90° ashunyekwe ezisele. I-main winding eyinhloko ixhunywe kugesi we-AC, futhi i-winging eyisizayo ixhunywe ochungechungeni ku-switch centrifugal S noma i-capacitor yokuqala, i-capacitor egijima, njll., bese ixhunywe kugesi. I-rotor iyi-rotor ye-aluminium yohlobo lwekheji. I-iron core i-laminated bese i-aluminium iphonswa endaweni yensimbi. Amasongo okugcina nawo ahlanganiswe ndawonye ukuze kufinyezwe imigoqo yomhlahlandlela we-rotor ibe uhlobo lwekheji ye-squirrel.
I-single-phase-asynchronous motors iphinde ihlukaniswe ibe yi-single-phase resistance-start-asynchronous motors, i-single-phase capacitor-start asynchronous motors, i-single-phase capacitor-run asynchronous motors kanye nesigaba esisodwa esikabili-value capacitor asynchronous motors.
I-2.Isakhiwo esiyisisekelo se-asynchronous motor enezigaba ezintathu
I-asynchronous motor enezigaba ezintathu ikakhulukazi iqukethe i-stator, i-rotor nama-bearings. I-stator yakhiwe ikakhulukazi i-iron core, izigaba ezintathu ezijikajikayo, uhlaka kanye nesembozo sokugcina. I-stator core ivamise ukushaywa futhi ifakwe elayiniwe kusuka kumashidi ensimbi ye-silicon engu-0.35~0.5 mm enongqimba oluvikelayo ngaphezulu. Kukhona izikhala ezisatshalaliswe ngokulinganayo ezibethelwe kusiyingi sangaphakathi somongo ukuze kushumeke ama-winding stator. Ukusonteka kwezigaba ezintathu kwakhiwe amajika amathathu anesakhiwo esifanayo ahlukaniswe ngo-120° ukusuka kwenye futhi ahlelwe ngokulinganayo. Ikhoyili ngayinye yala ma-windings ifakwe ku-slot ngayinye ye-stator ngokuvumelana nemithetho ethile. Umsebenzi wawo uwukudlula ngezigaba ezintathu zamanje ezishintshanayo bese ukhiqiza inkambu yakazibuthe ezungezayo. Isisekelo ngokuvamile senziwe ngensimbi eyinsimbi. Isisekelo sama-asynchronous motors ngokuvamile sishiselwa ngamapuleti ensimbi. Isisekelo se-micro motors senziwe nge-aluminium ekhonjiwe. Umsebenzi wayo ukulungisa i-stator core kanye nekhava yangaphambili nangemuva ukuze isekele i-rotor, futhi idlale indima ekuvikelweni nasekulahlekeni kokushisa. Kukhona izimbambo ezikhipha ukushisa ngaphandle kwesisekelo senjini evaliwe ukuze kwandiswe indawo yokukhipha ukushisa. Izembozo zokugcina kuzo zombili iziphetho zesisekelo senjini evikelekile zinezimbobo zokungenisa umoya ukuze zivumele ukuqhutshwa komoya okuqondile ngaphakathi nangaphandle kwenjini ukuze kube lula ukunqanyulwa kokushisa. Isembozo sokugcina ngokuyinhloko sidlala indima yokulungisa i-rotor, ukuyisekela nokuyivikela. I-rotor ikakhulukazi yakhiwe i-iron core nama-windings.
I-rotor core yenziwe ngezinto ezifanayo njenge-stator. Ishaywa futhi i-laminated kusuka ku-0.5 mm amashidi ensimbi ye-silicon. Indilinga yangaphandle yamashidi ensimbi ye-silicon ibhontshiwe ngezimbobo ezisatshalaliswe ngokulinganayo zokubeka ama-rotor windings. Imvamisa, indingilizi yangaphakathi yeshidi lensimbi ye-silicon ekhishwe ku-stator core isetshenziselwa ukubhoboza i-rotor core. Ngokuvamile, i-rotor core yama-motor amancane asynchronous icindezelwa ngokuqondile ku-shaft ejikelezayo, kuyilapho i-rotor core yama-asynchronous motors amakhulu naphakathi (ububanzi be-rotor bungaphezu kuka-300 ~ 400 mm) icindezelwa ku-shaft ejikelezayo ngosizo lwe ubakaki rotor.
