Waa maxay sababta Shiinuhu u horumarinayo matoorada isku-dhafka magnet-ka joogtada ah?

Marka la barbar dhigo matoorrada asynchronous, matoorada synchronous magnet joogto ah waxay leeyihiin faa'iidooyin badan oo muuqda. Matoorada synchronous magnet joogto ah waxay leeyihiin sifooyin badan sida factor awood sare, index awoodda wadida wanaagsan, size yar, miisaanka fudud, kor u kaca heerkulka hooseeyo, iwm Isla mar ahaantaana, waxay si fiican u hagaajin karaan factor tayada shabakada korontada, siin ciyaar buuxda. in la awoodo shabkada korantada ee jirta, lana badbaadiyo maalgalinta korantada.

Waxtarka iyo isbarbardhigga qodobka awoodda

Motor Asynchronous ee shaqada, dabaylaha rotor ah si uu u nuugo qayb ka mid ah tamarta ka soo xamaasad shabagga, si isticmaalka awoodda shabakadaha, qaybtan ka mid ah awoodda ilaa hadda final ee rotor dabaylaha ee kulaylka wada baabbi'iyey, khasaaraha xisaabiyaa. qiyaastii 20-30% ee wadarta guud ee luminta mootada, taas oo si toos ah u horseedaysa hoos u dhaca waxtarka mashiinka. Rotor excitation hadda loo rogo dabaylaha stator waa inductive hadda, si ay hadda galay dabaylaha stator ka dambeeya danab shabagga, taasoo keentay in hoos u dhac in factor awood ee motor ka.

Intaa waxaa dheer, matoorka asynchronous ee culeyska culeyska (= P2 / Pn) <50%, hufnaantiisa hawleed iyo awoodda hawlgalka ayaa si weyn hoos ugu dhacday, sidaa darteed guud ahaan waxay u baahan tahay inay ka shaqeyso aagga dhaqaalaha, taas oo ah, heerka culeyska 75% - 100%

Matoorka joogtada ah ee magnet synchronous ee rotor-ka ee ku dhex jira magnetka joogtada ah, magnet joogto ah si loo dhiso garoonka magnetic rotor, hawlgalka caadiga ah, rotor iyo stator magnetic field synchronous, ma jiro hadda soo jiidasho leh ee rotor, ma jiro khasaare iska caabin rotor ah, Midkan kaliya ayaa kor u qaadi kara waxtarka matoorka 4% ilaa 50%. Isla mar ahaantaana, sababtoo ah ma jiro induction induction hadda excitation ee rotor ee motor synchronous magnet joogto ah, dabaysha stator waxaa laga yaabaa in load kaliya iska caabin ah, si factor awood ee motor waa ku dhawaad ​​1. magnet joogto ah synchronous motor in heerka load ah. > 20%, hufnaantiisa hawleed iyo qodob awood hawleed oo wax yar iska beddeleen, hufnaanta hawleedkuna waa> 80%.

Bilaabida qulqulka

Matoor Asynchronous bilaabay, matoorka waxaa looga baahan yahay in ay leeyihiin xoog bilow weyn oo ku filan, laakiin rajaynaynaa in hadda bilowga ah ma aha mid aad u weyn, si aanay u soo saaro hoos u dhac danab xad-dhaaf ah ee shabakadaha oo saamayn hawlgalka caadiga ah ee matoorrada kale iyo qalabka korontada ku xiran. ilaa shabkada. Intaa waxaa dheer, marka bilawga bilawga ah uu aad u weyn yahay, matoorka laftiisa ayaa la kulmi doona saameyn xoog leh oo koronto ah, haddii marar badan la bilaabo, waxaa jira khatar ah kulaylka bararka. Sidaa darteed, naqshadaynta bilawga mootada asynchronous waxaa badanaa la kulma laba daran.

Matoorka joogtada ah ee magnet synchronous sidoo kale waxaa loo isticmaali karaa qaabka bilawga ah, sababtoo ah magnet-ka joogtada ah ee dhaqdhaqaaqa caadiga ah ee wareegga wareegga ma shaqeeyo, naqshadeynta mashiinka magnetka joogtada ah, dabaysha rotor ayaa la samayn karaa si buuxda u buuxiso shuruudaha torque bilawga sare, tusaale ahaan, si ay u dhufto bilawga bilawga ah ee mashiinka asynchronous 1.8 jeer ilaa 2.5 jeer, ama xitaa ka weyn, xal ka fiican qalabka caadiga ah, Waxay si wax ku ool ah u xallisaa ifafaalaha "fardo waaweyn oo jiidaya baabuur yart” qalabka korontada ee caadiga ah.

Hawlgalkakor u kaca heerkulka

Sida matoorka asynchronous uu shaqeeyo, rotor-ka qulqulaya qulqulka hadda jira, iyo hadda tani waa gebi ahaanba qaabka isticmaalka tamarta kulaylka, sidaas darteed wareegga rotor wuxuu soo saari doonaa kulayl badan, si heerkulka matoorku kor u kaco, kaas oo si dhab ah u saameeya. nolosha adeegga matoorka.

Sida motor synchronous magnet joogto ah, ay sabab u tahay oolnimada sare ee motor magnet joogto ah, ma jirto khasaaro iska caabin ah in dabaylaha rotor ah, waxaa jira wax ka yar ama ku dhawaad ​​ma hadda fal-celin in dabaylaha stator ah, si kor u kaca heerkulka motor hooseeyo. , kaas oo si fiican u kordhiya nolosha adeegga matoorka.

Saamayn ku yeelashada hawlgalka xadhkaha

Sababtoo ah qodobka awoodda hoose ee mishiinka asynchronous, matoorku wuxuu u baahan yahay inuu nuugo qadar badan oo firfircooni ah oo ka yimaada korantada korantada, sidaas awgeed waxay keenaysaa xaddi badan oo fal-celin ah oo ka mid ah shabakada korontada, qalabka gudbinta iyo isbeddelka iyo qalabka korontada, sidaas darteed samaynta Qodobka tayada tayada korontadu hoos u dhaco, taas oo aan kaliya sii xumeynin culeyska korantada korontada iyo gudbinta iyo qalabka isbeddelka iyo qalabka korontada, isla mar ahaantaana, falcelinta firfircooni waxay isticmaashaa qayb ka mid ah korantada korontada ku jirta shabakada korontada, qalabka gudbinta iyo isbeddelka iyo qalabka koronto-dhalinta, taasoo keentay waxtarka hooseeya oo saameeya koronto-korontada. Isla mar ahaantaana, firfircoonida firfircooni waxay isticmaashaa qayb ka mid ah tamarta korantada ee korontadu, qalabka gudbinta iyo isbeddelka iyo qalabka koronto-dhalinta, taas oo keenta in korontadu ay noqoto mid tayo yar oo saameynaysa isticmaalka waxtarka leh ee tamarta korontada. Sidoo kale, sababtoo ah waxtarka hooseeya ee matoorrada asynchronous, si loo daboolo baahida tamarta wax soo saarka, waxaa lagama maarmaan ah in la nuugo koronto badan oo ka mid ah shabakadaha, sidaas darteed kordhinta lumista tamarta korontada iyo sii xumeynta culeyska shabkada.

Iyo motor synchronous magnet joogto ah, ay rotor iyada oo aan induction kicinta hadda, factor awoodda motor sidoo kale waa mid sare, taas oo aan kaliya hagaajin tayada shabagga ah, si grid mar dambe uma baahna in la rakibo qalabka magdhow tamarta falcelin. Waxaa intaa dheer, ay sabab u tahay waxtarka sare ee motor synchronous magnet joogto ah, waxa kale oo ay badbaadisaa awoodda shabakadaha.

Anhui Mingteng Permanent-Magnetic Machinery&Equipment Electric Co., Ltdwaxaa la aasaasay 2007 waana mid ka mid ah soosaarayaasha ugu horreeya ee Shiinaha si ay u horumariyaan una soo saaraan matoorada magnetka joogtada ah. Waxay leedahay R&D dhamaystiran, wax soo saarka, iibka, iyo kooxda iibka kadib. Shirkaddu had iyo jeer waxay u hoggaansantaa hal-abuurnimo madax-bannaan waxayna u hoggaansamaan siyaasadda shirkadda ee "wax soo saarka fasalka koowaad, maamulka heerka koowaad, adeegyada fasalka koowaad, iyo noocyada heerka koowaad", habaynta caqli-galnimada nidaamka magnetka joogtada ah ee nidaamka tamarta-badbaadinta xalalka guud ee isticmaalayaasha , oo ku dadaalaya in ay noqdaan hogaamiye iyo jaangooyo jaangooyo warshadaha mishiinka magnetka joogtada ah ee dhulka Shiinaha ee dhifka ah.
