Gufata moteri ya moteri itezimbere kwizerwa rya moteri ikoreshwa na Inverter

Abashinzwe gufata neza hejuru yinyubako zubucuruzi cyangwa inganda zinganda bahora basubizamo moteri kandi bakagenzura ibindi bimenyetso by umunaniro, kandi nta bikoresho byo kubungabunga ibidukikije cyangwa porogaramu igezweho yo kugenzura ibyateganijwe kugirango batange integuza, injeniyeri barashobora guhagarara bagatekereza bati: "Izi moteri nizihe? bigenda byiyongera? ”Biragenda byiyongera, cyangwa ibi ni ibitekerezo byanjye gusa? ”Inzobere za injeniyeri w'inararibonye (kumva) hamwe na hunches (impuruza zo guhanura) za moteri birashobora kuba ukuri, mugihe kirenze, ibyuma biri hagati yabantu.Kwambara imburagihe murubanza, ariko kubera iki?Menya iyi "shyashya" itera kwihanganira kunanirwa kandi umenye uburyo bwo kuyirinda ukuraho amashanyarazi asanzwe.

Kuki moteri inanirwa?

Mugihe hariho impamvu nyinshi zitandukanye zitera gutsindwa na moteri, umubare wambere utera, igihe nigihe kimwe, ni ukunanirwa.Moteri yinganda ikunze guhura nibidukikije bitandukanye bishobora kugira ingaruka mbi kubuzima bwa moteri.Mugihe umwanda, ubushuhe, ubushyuhe cyangwa gupakira nabi bishobora rwose gutera kunanirwa kubyara imburagihe, ikindi kintu gishobora gutera kunanirwa ni voltage isanzwe.

Uburyo busanzwe bwa voltage

Moteri nyinshi zikoreshwa muri iki gihe zikora kuri voltage yambukiranya umurongo, bivuze ko zahujwe mu buryo butaziguye n’amashanyarazi y'ibice bitatu yinjira mu kigo (binyuze kuri moteri itangira).Moteri itwarwa na drives ya variable ya drives imaze kuba rusange nkuko porogaramu zabaye ingorabahizi mumyaka mike ishize.Inyungu yo gukoresha moteri ihindagurika kugirango utware moteri nugutanga umuvuduko mubisabwa nka bafana, pompe na convoyeur, kimwe no gutwara imizigo muburyo bwiza bwo kuzigama ingufu.

Imwe mu mbogamizi ya drives ihindagurika, icyakora, nubushobozi bwumubyigano usanzwe, ushobora guterwa nubusumbane hagati yimodoka ya feri eshatu zinjiza.Ihinduranya ryihuse rya pulse-ubugari-bwahinduwe (PWM) inverter irashobora gutera ibibazo kubibazo byo guhinduranya moteri no gutwara ibintu, guhinduranya birinzwe neza hamwe na sisitemu yo kurwanya anti-spike, ariko iyo rotor ibonye imitwe ya voltage irundanya, ikigezweho ishakisha Inzira kugirango byibuze irwanya ubutaka: binyuze mumutwe.

Ibikoresho bya moteri bisizwe amavuta, kandi amavuta yo mumavuta akora firime ikora nka dielectric.Igihe kirenze, iyi dielectric irasenyuka, urwego rwa voltage mumashanyarazi rwiyongera, ubusumbane bwubu burashaka inzira yuburwanya buke binyuze mumyuka, itera ubwikorezi kuri arc, bakunze kwita EDM (Machine Discharge Machining).Igihe kirenze, iyi arcing ihoraho ibaho, ubuso bwubuso bwamoko yabyaye buba bworoshye, kandi uduce duto twibyuma imbere mubitereko birashobora gucika.Ubwanyuma, ibi bintu byangiritse bigenda hagati yumupira wogutwara nubwoko bwo gutwara, bigatera ingaruka mbi zishobora gutera ubukonje cyangwa ibiti (kandi bishobora kongera urusaku rwibidukikije, kunyeganyega, nubushyuhe bwa moteri).Mugihe ibintu byifashe nabi, moteri zimwe zirashobora gukomeza gukora, kandi bitewe nuburemere bwikibazo, amaherezo kwangirika kwimodoka bishobora byanze bikunze kuko ibyangiritse bimaze gukorwa.

bishingiye ku gukumira

Nigute ushobora gutandukanya imiyoboro iva?Igisubizo gikunze kugaragara nukwongeramo igitaka kumutwe umwe wa moteri ya moteri, cyane cyane mubisabwa aho amashanyarazi asanzwe ashobora kuba menshi.Gufata shitingi ni uburyo bwo guhuza rotor ya rotor ya moteri hasi ikoresheje ikarita ya moteri.Ongeraho igitaka kuri moteri (cyangwa kugura moteri yabanje gushyirwaho) mbere yo kwishyiriraho birashobora kuba igiciro gito ugereranije namafaranga yo kubungabunga ajyanye no gusimbuza, tutibagiwe nigiciro kinini cyibikoresho byo hasi.

Ubwoko butandukanye bwubutaka bwa shaft buramenyerewe muruganda muri iki gihe.Gushiraho karubasi ya karubone kumurongo iracyakunzwe.Ibi birasa na DC ya karubone isanzwe, itanga cyane cyane amashanyarazi hagati yibizunguruka nibihagarara byumuzingi wa moteri..Ubwoko bushya bwibikoresho ku isoko nigikoresho cya fibre brush ya fibre, ibyo bikoresho bikora muburyo busa na brux ya karubone ushyira imirongo myinshi ya fibre ikora mumuzingi uzengurutse uruziga.Hanze yimpeta iguma ihagaze kandi mubisanzwe ishyirwa kumurongo wanyuma wa moteri, mugihe umwanda ugenda hejuru yumutwe wa moteri, ugahindura umuyaga unyuze muri bruwasi hanyuma ugahagarara neza.Nyamara, kuri moteri nini (hejuru ya 100hp), hatitawe ku gikoresho cyo hasi cya shaft cyakoreshejwe, muri rusange birasabwa gushyiramo insuline yometse ku rundi ruhande rwa moteri aho hashyizweho igikoresho cyo guhagarika shaft kugira ngo voltage zose ziri muri rotor yasohotse binyuze mu gikoresho cyo hasi.

mu gusoza

Imiyoboro ihindagurika irashobora kubika ingufu mubikorwa byinshi, ariko nta guhagarara neza, birashobora gutera moteri itaragera.Hano haribintu bitatu ugomba gusuzuma mugihe ugerageza kugabanya voltage yuburyo busanzwe muri progaramu zihindagurika zikoreshwa: 1) Menya neza ko moteri (na sisitemu ya moteri) ihagaze neza.2) Menya neza uburyo bwiza bwo gutwara ibintu, bizagabanya urwego rwurusaku nuburinganire bwa voltage.3) Niba igiti cya shaft gifatwa nkigikenewe, hitamo ikibanza gikwiranye no gusaba.
