Uma kuqhathaniswa namamotho asynchronous, amamotho asebenza ngozibuthe ahambisanayo anezinzuzo eziningi ezisobala. Amamotho anobungane ozibuthe ahambisanayo anezici eziningi ezifana nesici samandla aphezulu, inkomba yekhono elihle lokushayela, usayizi omncane, isisindo esilula, ukukhuphuka kwezinga lokushisa eliphansi, njll. Ngesikhathi esifanayo, angathuthukisa kangcono isici sekhwalithi yegridi yamandla, anikeze ukudlala okugcwele. kumthamo wegridi yamandla ekhona, futhi wonge ukutshalwa kwezimali kwegridi yamandla.
Ukusebenza kahle kanye nokuqhathaniswa kwesici samandla
I-asynchronous motor emsebenzini, i-rotor emazombezombe ukuze imunce ingxenye yamandla avela kugridi, ukuze ukusetshenziswa kwamandla egridi, le ngxenye yamandla kuze kube yamanje yokugcina ku-rotor ephendukayo ekushiseni okusetshenzisiwe, i-akhawunti yokulahlekelwa cishe u-20-30% wokulahlekelwa okuphelele kwemoto, okuholela ngokuqondile ekunciphiseni ukusebenza kahle kwemoto. I-Rotor excitation current eguqulelwe ku-stator winding iyi-inductive current, ukuze i-current in the stator winding ibambezeleka ngemuva kwe-voltage yegridi, okuholela ekuncipheni kwesici samandla enjini.
Ngaphezu kwalokho, i-asynchronous motor endaweni yokulayisha (= P2 / Pn) <50%, ukusebenza kahle kwayo nokusebenza kwamandla okusebenzayo kwehla kakhulu, ngakho-ke ngokuvamile idinga ukuthi isebenze endaweni yezomnotho, okungukuthi, izinga lokulayisha lika-75% - 100%.
Unomphela uzibuthe motor synchronous ku-rotor eshumekwe uzibuthe unomphela, uzibuthe unomphela ukusungula insimu kazibuthe rotor, ekusebenzeni okuvamile, i-rotor kanye stator magnetic field synchronous operation, akukho yamanje in the rotor, akukho rotor ukumelana ukulahlekelwa, yilokhu kuphela okungathuthukisa ukusebenza kahle kwenjini ngo-4% kuya ku-50%. Ngasikhathi sinye, ngenxa yokuthi akukho ukuvuswa kwamanje kokungeniswa ku-rotor ye-synchronous motor yamagnetic unomphela, ukuvuthwa kwe-stator kungase kube umthwalo ophikisanayo, ukuze isici samandla semoto sicishe sibe ngu-1. > 20%, ukusebenza kahle kwayo kanye nezici zamandla okusebenza ezinoshintsho oluncane, nokusebenza kahle kokusebenza kungu-> 80%.
I-torque yokuqala
Ukuqala kwe-asynchronous motor, i-motor iyadingeka ukuthi ibe ne-torque enkulu ngokwanele yokuqala, kodwa ngethemba ukuthi i-current current ayinkulu kakhulu, ukuze ingakhiqizi ukwehla kwe-voltage ngokweqile kugridi futhi ithinte ukusebenza okuvamile kwamanye ama-motor kanye nemishini kagesi exhunyiwe. kugridi. Ngaphezu kwalokho, lapho i-current yokuqala inkulu kakhulu, i-motor ngokwayo izoba nomthelela omkhulu wamandla kagesi, uma kuvame ukuqala, kunengozi yokushisa ngokweqile ama-windings. Ngakho-ke, idizayini yokuqala ye-asynchronous motor ivame ukubhekana nenkinga.
I-Permanent magnet synchronous motor ingasetshenziswa futhi imodi yokuqala eyi-asynchronous, ngenxa yokusebenza okujwayelekile kukazibuthe okuhambisanayo kwe-rotor winding akusebenzi, ekwakhiweni kwemoto kazibuthe unomphela, ukujikajika kwe-rotor kungenziwa ukuze kuhlangatshezwane ngokugcwele nezidingo ze i-torque yokuqala ephezulu, ngokwesibonelo, ukuze i-torque yokuqala iphindaphinde nge-asynchronous motor izikhathi ezingu-1.8 kuya ku-2.5 izikhathi, noma ngisho nangaphezulu, isisombululo esingcono semishini yamandla evamile, Ixazulula ngokuphumelelayo isimo "somahhashi amakhulu adonsa imoto encane.t” emishinini evamile yamandla.
Ukusebenzaukunyuka kwezinga lokushisa
Njengomsebenzi we-asynchronous motor, ukugeleza kwamanje kwe-rotor, futhi lokhu okwamanje kusesimweni sokusetshenziswa kwamandla ashisayo, ngakho-ke ku-rotor mawinding kuzokhiqiza ukushisa okukhulu, ukuze izinga lokushisa lemoto likhuphuke, elithinta kakhulu. impilo yesevisi yemoto.
Ngokuqondene ne-motor synchronous yamagnetic unomphela, ngenxa yokusebenza kahle okuphezulu kwemoto kazibuthe unomphela, akukho ukulahleka kokumelana kumajika e-rotor, kukhona okuncane noma cishe akukho okwamanje okusebenzayo ekujikeni kwe-stator, ukuze ukunyuka kwezinga lokushisa kwemoto kube phansi. , okwandisa kangcono impilo yesevisi yemoto.
Umthelela ekusebenzeni kwegridi
Ngenxa yesici samandla aphansi we-asynchronous motor, injini idinga ukumunca inani elikhulu lamanje elisebenzayo kusuka kugridi yamandla, ngaleyo ndlela ibangele inani elikhulu lamanje elisebenzayo kugridi yamandla, imishini yokudlulisela kanye nenguquko kanye nemishini yokuphehla amandla, ngaleyo ndlela isici sekhwalithi yokuncipha kwegridi yamandla, okungagcini nje kwandise umthwalo wegridi yamandla kanye nemishini yokudlulisela nokuguqula kanye nemishini yokuphehla amandla, ngesikhathi esifanayo, amandla asebenzayo asebenzisa ingxenye yamandla kagesi kugridi yamandla, ukudlulisa kanye imishini yokuguqula kanye nempahla yokuphehla ugesi, okuholela ekusebenzeni kahle okuphansi futhi kuthinte igridi yamandla kagesi. Ngesikhathi esifanayo, amandla asebenzayo asebenzisa ingxenye yamandla kagesi kugridi yamandla, amathuluzi okudlulisa nokuguqula kanye nempahla yokuphehla amandla, okubangela ukuthi igridi yamandla ingasebenzi kahle futhi ithinte ukusetshenziswa ngempumelelo kwamandla kagesi. Ngokufanayo, ngenxa yokusebenza kahle okuphansi kwama-asynchronous motors, ukuze kuhlangatshezwane nesidingo samandla aphumayo, kuyadingeka ukumunca amandla engeziwe kugridi, ngaleyo ndlela kukhulise ukulahlekelwa kwamandla kagesi futhi kubhebhethekise umthwalo kugridi.
Futhi nge-motor synchronous yamagnetic unomphela, i-rotor yayo ngaphandle kwe-excitation yamanje yokungeniswa, i-motor power factor nayo iphakeme, engathuthukisi nje kuphela isici sekhwalithi yegridi, ukuze igridi ingasadingeki ukufaka imishini yesinxephezelo samandla asebenzayo. Ngaphezu kwalokho, ngenxa yokusebenza kahle okuphezulu kwe-magnetic synchronous motor unomphela, iphinde isindise amandla egridi
I-Anhui Mingteng Permanent-Magnetic Machinery&Electrical Equipment Co., Ltdyasungulwa ngo-2007 futhi ingomunye wabakhiqizi bokuqala eChina ukuthuthukisa nokukhiqiza amamotho kazibuthe ahlala njalo. Ine-R&D ephelele, ukukhiqiza, ukuthengisa, nethimba lokuthengisa ngemuva kokuthengisa. Le nkampani ihlale inamathela emisha ezimele futhi ibambelela kunqubomgomo yebhizinisi "yemikhiqizo yezinga lokuqala, ukuphathwa kwesigaba sokuqala, izinsizakalo ezisezingeni lokuqala, nemikhiqizo yezinga lokuqala", ihlanganisa izixazululo ezihlakaniphile zikazibuthe unomphela zokonga amandla jikelele kubasebenzisi. , nokulwela ukuba umholi kanye nesethi ejwayelekile embonini yezimoto zikazibuthe zomhlaba ezingavamile yaseChina.
