Kwiminyaka yakutshanje, iimotor ezisisigxina zemagnethi eziqhuba ngokuthe ngqo zenze inkqubela phambili kwaye zisetyenziswa ikakhulu kwimithwalo enesantya esisezantsi, njengabahambisi bebhanti, abaxube, oomatshini bokuzoba ngocingo, iimpompo ezinesantya esiphantsi, ezithatha indawo yeenkqubo zombane ezenziwe ngeenjini ezinesantya esiphezulu kunye noomatshini. iindlela zokunciphisa.Uluhlu lwesantya senjini ngokubanzi lungaphantsi kwama-500rpm.Iimotor ezisisigxina zemagnethi zokuqhuba ngokuthe ngqo zinokuhlulwa zibe ziifom ezimbini: irotor yangaphandle kunye nerotor yangaphakathi.I-rotor yangaphandle esisigxina yemagnethi drive ngqo isetyenziswa ikakhulu kubahambisi bebhanti.
Kuyilo kunye nokusetyenziswa kweenjini ezisisigxina zemagnethi zokuqhuba ngokuthe ngqo, kufuneka kuqatshelwe ukuba imagnethi esisigxina yokuqhuba ngokuthe ngqo ayifanelekanga kwizantya ezisezantsi zemveliso.Xa uninzi lwemithwalo ngaphakathi5I-0r / min iqhutywa yi-motor drive ethe ngqo, ukuba amandla ahlala ehleli, aya kubangela i-torque enkulu, ekhokelela kwiindleko eziphezulu zemoto kunye nokunciphisa ukusebenza kakuhle.Xa amandla kunye nesantya simisiwe, kuyafuneka ukuba kuthelekiswe ukusebenza kakuhle kwezoqoqosho ngokudityaniswa kweenjini zokuqhuba ngokuthe ngqo, iimotor ezinesantya esiphezulu kunye neegiya (okanye esinye isantya esonyukayo kunye nokuncipha kwezakhiwo zoomatshini).Okwangoku, iiinjini zomoya ezingaphezulu kwe-15MW nangaphantsi kwe-10rpm ngokuthe ngcembe zamkela iskimu sokuqhuba, zisebenzisa iigiya ukunyusa isantya semoto ngokufanelekileyo, ukunciphisa iindleko zemoto, kwaye ekugqibeleni zithobe iindleko zenkqubo.Kukwasebenza okufanayo kwiinjini zombane.Ngoko ke, xa isantya singaphantsi kwe-100 r / min, ukuqwalaselwa kwezoqoqosho kufuneka kuqwalaselwe ngokucophelela, kwaye i-semi-direct drive scheme inokukhethwa.
Iimotor ezisisigxina zemagnethi eziqhuba ngokuthe ngqo zihlala zisebenzisa iirotor zemagnethi ezixhonywe ngokusisigxina ukwandisa ubuninzi betorque kunye nokunciphisa ukusetyenziswa kwezinto.Ngenxa yesantya esisezantsi sokujikeleza kunye namandla amancinci e-centrifugal, akuyimfuneko ukusebenzisa isakhiwo se-rotor esisisigxina esakhelwe ngaphakathi.Ngokubanzi, imivalo yoxinzelelo, imikhono yensimbi engenasici, kunye nemikhono ekhuselayo yefiberglass isetyenziselwa ukulungisa nokukhusela imagnethi esisigxina yerotor.Nangona kunjalo, ezinye iimoto ezineemfuno zokuthembeka okuphezulu, amanani amancinci epali, okanye ii-vibrations eziphezulu zikwasebenzisa izakhiwo zerotor eyakhelweyo ngaphakathi.
Injini enesantya esisezantsi ngqo iqhutywa sisiguquli samaza.Xa idizayini yenombolo yepali ifikelela kumda ophezulu, ukuncitshiswa okungaphezulu kwesantya kuya kubangela ukuphindaphindeka okuphantsi.Xa i-frequency ye-frequency converter iphantsi, umjikelo womsebenzi we-PWM uyancipha, kwaye i-waveform imbi, nto leyo inokukhokelela ekuguquguqukeni kunye nesantya esingazinzanga.Ke ukulawulwa kweenjini zokuqhuba ngokuthe ngqo ngesantya esisezantsi nako kunzima kakhulu.Okwangoku, ezinye iinjini zesantya esisezantsi kakhulu zisebenzisa isikimu semodyuli yemagnethi yomhlaba ukuze zisebenzise amaza okuqhuba aphezulu.
Isantya esisezantsi semagnethi esisigxina yeenjini zokuqhuba ngokuthe ngqo zinokupholiswa ngumoya kunye nolwelo olupholileyo.Ukupholisa komoya ikakhulu kwamkela indlela yokupholisa ye-IC416 yabalandeli abazimeleyo, kwaye ukupholisa ulwelo kunokuba kukupholisa kwamanzi (IC71W), enokuthi igqitywe ngokwemiqathango ye-site.Kwimowudi yokupholisa ulwelo, umthwalo wobushushu unokuyilwa phezulu kwaye ulwakhiwo luxinene ngakumbi, kodwa ingqalelo kufuneka ihlawulwe ekwandiseni ubukhulu bemagnethi esisigxina ukuthintela i-demagnetization engaphaya.
Kwiinkqubo zeemoto ezihamba ngesantya esisezantsi ezineemfuno zesantya kunye nolawulo lokuchaneka kwesikhundla, kuyafuneka ukuba ukongeza abenzi boluvo bendawo kwaye bamkele indlela yokulawula kunye nezimvo zesikhundla;Ukongeza, xa kukho imfuneko ephezulu yetorque ngexesha lokuqalisa, indlela yokulawula enenzwa yendawo nayo iyafuneka.
Nangona ukusetyenziswa kwemagnethi esisigxina yeenjini zokuqhuba ngokuthe ngqo kunokuphelisa indlela yokwehliswa kwasekuqaleni kunye nokunciphisa iindleko zokuyigcina, uyilo olungekho ngqiqweni lunokukhokelela kwiindleko eziphezulu zeenjini ezisisigxina zemagnethi zokuqhuba ngokuthe ngqo kunye nokuncipha kokusebenza kakuhle kwenkqubo.Ngokubanzi, ukonyusa idiameter yemagnethi esisigxina yeenjini zokuqhuba ngokuthe ngqo kunokunciphisa iindleko ngeyunithi yetorque, ngoko ke iimotor zokuqhuba ngokuthe ngqo zinokwenziwa zibe yidiski enkulu enobubanzi obukhulu kunye nobude besitaki esifutshane.Nangona kunjalo, kukho imida yokunyuka kobubanzi.Ubukhulu obukhulu kakhulu kunokunyusa iindleko ze-casing kunye ne-shaft, kwaye kunye nezixhobo zokwakha ziya kudlula ngokuthe ngcembe ixabiso lezinto ezisebenzayo.Ke ukuyila i-motor yokuqhuba ngokuthe ngqo kufuna ukwandiswa kobude ukuya kumlinganiselo wedayamitha ukunciphisa iindleko zizonke zemoto.
Okokugqibela, ndingathanda ukugxininisa ukuba iimotor ezisisigxina zemagnethi eziqhuba ngqo zisezimotor eziqhutywa rhoqo.Into yamandla emoto ichaphazela okwangoku kwicala lemveliso ye-frequency converter.Ngethuba nje ingaphakathi kuluhlu lwamandla okuguqula amaza, amandla anamandla anempembelelo encinci ekusebenzeni kwaye ayiyi kuchaphazela amandla ombane kwicala legridi.Ke ngoko, uyilo lwamandla emoto kufuneka luzame ukuqinisekisa ukuba i-motor drive ngqo isebenza kwimowudi ye-MTPA, evelisa i-torque ephezulu ngobuncinci bangoku.Isizathu esibalulekileyo kukuba i-frequency ye-direct drive motors iphantsi ngokubanzi, kwaye ilahleko yentsimbi iphantsi kakhulu kunokulahleka kobhedu.Ukusebenzisa indlela ye-MTPA kunokunciphisa ukulahleka kobhedu.Amagcisa akufuneki aphenjelelwe yigridi yemveli eqhagamshelwe iimotor ze-asynchronous, kwaye akukho siseko sokugweba ukusebenza kakuhle kwemoto esekelwe kubukhulu bangoku kwicala lemoto.
