Umshini oguqula amandla kagesi abe amandla omshini ubizwa ngokuthi i-electric motor. Lawa alula ngokuklama, asetshenziswa kalula, ashibhile, asebenza kahle kakhulu, aphansi ekunakekelweni, futhi athembekile. Ama-induction motor anezigaba ezintathu angenye yezinhlobo futhi ahlukile kwezinye izinhlobo zama-electric motor. Umehluko omkhulu ukuthi akukho ukuxhumana kukagesi kusuka ekugoqeni kwe-rotor kuya kunoma yimuphi umthombo wokunikezwa. Amandla kagesi kanye ne-voltage edingekayo kusekethe ye-rotor kunikezwa yi-induction evela ekugoqeni kwe-stator. Lesi yisizathu sokubiza i-is njenge-induction motor. Lesi sihloko sichaza i-induction motor ye-Squirrel cage, engenye yezinhlobo zama-induction motor anezigaba ezintathu.
Iyini i-Squirrel Cage Induction Motor?
Incazelo: Injini yekheji likaSquirrel ingenye yezinhlobo zama-induction motors. Ukuze ikhiqize ukunyakaza, iqinisa i-electromagnetism. Njengoba i-output shaft ixhunywe engxenyeni yangaphakathi ye-rotor ebukeka njengekheji. Ngakho-ke ibizwa ngokuthi ikheji likasquirrel. Ama-caps amabili okungukuthi, ayindilinga ngesimo ahlanganiswe yi-rotor bars. Lawa asebenza ngokusekelwe ku-EMF okungukuthi, akhiqizwa yi-stator. Le EMF iphinde ikhiqizwe indlu yangaphandle eyenziwe ngamashidi ensimbi alaminated kanye ne-wire coiling. Izingxenye ezimbili eziyinhloko zanoma yiluphi uhlobo lwenjini ye-induction yi-stator kanye ne-rotor. Ikheji likasquirrel liyindlela elula yokudonsa umphumela we-electromagnetic induction. Injini ye-induction yekheji likasquirrel enama-pole amane iboniswe ngezansi.
Isimiso Sokusebenza Semoto Yokungenisa I-Squirrel Cage
Ukusebenza kwenjini yokungenisa i-squirrel kusekelwe esimisweni se-electromagnetism. Lapho i-stator winding inikezwa i-AC yesigaba se-thee, ikhiqiza insimu yamagnetic ejikelezayo (RMF) enesivinini esibizwa ngokuthi isivinini esihambisanayo. Le RMF ibangela i-voltage ebangelwa yi-rotor bars. Ngakho-ke, lowo mshini ugeleza kulokho. Ngenxa yale mishini yamandla e-rotor, kukhiqizwa insimu yamandla kagesi esebenzisana nensimu ye-stator. Manje, ngokwesimiso, insimu yamandla e-rotor iqala ukuphikisa imbangela yayo. lapho i-RMF ibamba umzuzu we-rotor, umzuzu we-rotor wehla uye ku-zero. Khona-ke bekungeke kube khona umzuzu ohlobene phakathi kwe-rotor ne-RMF.
Ngakho-ke, amandla angewona ama-tangential atholakala yi-rotor futhi anciphe okwesikhashana. Ngemva kwalokhu kuncipha ngesikhathi se-rotor, ugesi we-rotor uphinde ubangelwe ukwakhiwa kabusha kokunyakaza okuhlobene phakathi kwe-RMF ne-rotor. Ngakho-ke amandla angewona ama-tangential e-rotor yokujikeleza ayabuyiselwa futhi aqale ngokulandela i-RMF. Kulesi simo, i-rotor igcina ijubane elingaguquki, elingaphansi kwejubane le-RMF kanye nejubane elihambisanayo. Lapha, umehluko phakathi kwejubane le-RMF ne-rotor ulinganiswa ngesimo sokushelela. Imvamisa yokugcina ye-rotor ingatholakala ngokuphindaphindwa kokushelela kanye nemvamisa yokunikezwa.
Ukwakhiwa Kwemoto Yokungenisa Ikheji Le-Squirrel
Izingxenye ezidingekayo ekwakhiweni kwenjini yokungenisa ikheji lesikwele yi-stator, i-rotor, i-fan, ama-bearings. I-stator yakhiwe ngokugoqana kwezigaba ezintathu okuhlukaniswe ngomshini nangogesi okungama-degree angu-120 okunezindlu zensimbi kanye nomgogodla. Ukuze kuhlinzekwe indlela yokungabaza okuphansi kokuguquguquka okukhiqizwa ugesi we-AC, ukugoqana kufakwe kumgogodla wensimbi onamathelisiwe.
I-Rotor iguqula amandla kagesi anikezwe abe umkhiqizo womshini. I-shaft, i-core, imigoqo yethusi efinyeziwe yizingxenye ze-rotor. Ukuze kugwenywe i-hysteresis kanye nemisinga ye-eddy eholela ekulahlekelweni kwamandla, i-rotor ifakwa i-laminate. Futhi ngiyala ukuvimbela ukugoba, ama-conductor ayagobeka futhi okusiza ukunikeza isilinganiso esihle sokuguqulwa.
Ifeni enamathiselwe ngemuva kwerotor ukuze kushintshwe ukushisa isiza ekugcineni izinga lokushisa lingaphansi komkhawulo wemoto. Ukuze kujikelezwe kahle, kuhlinzekwa amabheringi kumoto.
Umehluko phakathi kwe-Squirrel Cage Induction Motor kanye ne-Slip Ring Induction Motors.
