I-stator futhii-rotorizingxenye ezidingekayo ze-motor. I-stator igxilile endlini futhi ngokuvamile kukhona amakhoyili alimele ku-stator; i-rotor igxilwe ku-chassis ngokusebenzisa ama-bearings noma ama-bushings, futhi kukhona amashidi ensimbi ye-silicon namakhoyili ku-rotor, yamanje izokhiqiza insimu kazibuthe ku-stator kanye namashidi ensimbi ye-silicon ye-rotor ngaphansi kwesenzo samakhoyili, futhi insimu kazibuthe izoshayela i-rotor ukuthi ijikeleze.
Okokuqala, i-stator ye-asynchronous motor yenziwe nge-stator core, i-stator winding kanye nesihlalo.
1.Statorumnyombo
Indima ye-stator core ukusebenza njengengxenye yesekethe kazibuthe ye-motor kanye nama-stator winding ashumekiwe. Umgogodla we-stator wenziwe ngeshidi le-silicon eliwugqinsi elingu-0.5mm, futhi izinhlangothi ezimbili zeshidi lensimbi yezitini zimbozwe ngopende ovikelayo ukuze kuvikelwe ishidi ukusuka komunye nomunye ukuze kuncishiswe ukulahlekelwa okuyinhloko okubangelwa inkambu kazibuthe ezungezayo kumongo we-stator. . Indingilizi engaphakathi ye-stator core ishaywa ngenani lezikhala ezifanayo ukuze ushumeke i-stator winding.
2. I-Stator winding
I-stator winding iyingxenye yesifunda se-motor, umsebenzi wayo oyinhloko ukudlulisa okwamanje kanye nokukhiqiza amandla okungenisa ukuze kubonakale ukuguqulwa kwamandla kagesi. Amakhoyili asongayo e-Stator ahlukaniswe abe ungqimba olulodwa kanye nongqimba olukabili ku-stator slot. Ukuze uthole ukusebenza okungcono kwe-electromagnetic, amamotho aphakathi nendawo amakhulu asebenzisa iphimbo elifushane elinezendlalelo ezimbili.
3. Isihlalo se-Stator
Indima ye-chassis ngokuyinhloko ukulungisa nokusekela umgogodla we-stator, ngakho-ke kuyadingeka ukuthi ube namandla okwanele omshini nokuqina, ukwazi ukumelana nokusebenza kwezimoto noma inqubo yokuthutha yamandla ahlukahlukene. Injini ye-AC encane nephakathi nendawo - ukusetshenziswa okujwayelekile kwe-cast iron chassis, umthamo omkhulu we-AC motor, ukusetshenziswa okuvamile kwe-chassis yensimbi yokushisela.
Okwesibili, i-rotor ye-asynchronous motor yenziwe nge-rotor core, i-rotor winding kanye ne-rotor shaft, njll.
1. I-Rotor core
Ii-rotorumgogodla uyingxenye yomjikelezo kazibuthe wemoto. Yona kanye ne-stator core kanye negebe lomoya ndawonye bakha yonke isekethe kazibuthe yenjini. I-rotor core ngokuvamile yenziwe nge-silicone yensimbi engu-0.5mm ewugqinsi. Iningi lama-rotor cores of medium and small AC motors afakwe ngqo ku-motor shaft. I-rotor core yama-AC motors amakhulu ifakwe kubakaki be-rotor, ebekwe ku-rotor shaft.
2.I-Rotor winding rotor winding iyindima yekhono lokungeniswa, igeleza ku-current futhi ikhiqize i-torque ka-electromagnetic, ukwakheka kohlobo lwekheji yengwejeje kanye nohlobo lwesibili lwenxeba.
1. I-rotor yekheji ye-squirrel
I-squirrel cage rotor winding iwukuzivala ngokwayo. Kukhona ibha yomhlahlandlela efakwe ku-slot ngayinye, futhi kukhona izindandatho ezimbili zokugcina ezixhuma iziphetho zawo wonke amabha omhlahlandlela ezindaweni ezisuka ekugcineni komgogodla. Uma i-core isusiwe, ukuma kwayo yonke i-winging kufana "nekheji eliyindilinga", elibizwa ngokuthi i-squirrel-cage rotor.
2. I-rotor enenxeba
Ukusonteka kwe-rotor enenxeba kanye nokujikajika okungaguquki kufana nentambo evalekile eshumekwe ku-rotor core slot, futhi ixhunywe ekujikeni kwe-symmetric okume kwezigaba ezintathu okunjengenkanyezi. Khona-ke iziphetho ezintathu zocingo ezincane zixhunywe emasongweni amathathu okuqoqa ku-rotor shaft, bese i-current ikhishwa ngamabhulashi. Isici se-rotor ye-wire-nxeba ukuthi indandatho yokuqoqa kanye namabhulashi angaxhunywa kuma-resistors angaphandle kumjikelezo ojikelezayo ukuze kuthuthukiswe ukusebenza kokuqala kwe-motor noma ukulawula isivinini se-motor. Ukuze kuncishiswe ukuguga nokudabuka kwamabhulashi, ama-asynchronous motors anenxeba ngezinye izikhathi afakwe imishini yokunqamulela ibhulashi ukuze kuthi lapho injini isiqedile ukuqalisa futhi isivinini singadingi ukulungiswa, amabhulashi ayaphakanyiswa futhi abaqoqi abathathu. izindandatho zifinyezwa kanyekanye.
