Mkhulu kangakanani umsinga wokuqalisa wenjini?

Kukho izimvo ezahlukeneyo malunga nokuba mangaphi amaxesha isiqalo somjikelo wemoto silinganiswe ngoku, kwaye uninzi lwazo lusekwe kwiimeko ezithile.Njengamaxesha alishumi, 6 ukuya ku-8 amaxesha, 5 ukuya ku-8 amaxesha, 5 ukuya ku-7 amaxesha njalo njalo.

Enye into yokuba xa isantya semoto singu-zero ngexesha lokuqalisa (oko kukuthi, umzuzu wokuqala wenkqubo yokuqala), ixabiso langoku ngeli xesha kufuneka libe lixabiso layo langoku le-rotor.Uluhlu olusetyenziswa rhoqo lwe-Y lwesigaba sesithathu se-asynchronous motors, kukho imimiselo ecacileyo kwi-JB / T10391-2002 "Y uchungechunge lwezigaba ezintathu ze-asynchronous motors".Phakathi kwabo, ixabiso elichaziweyo lomlinganiselo we-rotor evaliweyo kwi-current rated current ye-5.5kW motor yile ilandelayo: kwi-synchronous speed ye-3000, umlinganiselo we-rotor evaliweyo kwi-current rated yi-7.0;kwisantya se-synchronous se-1500, umlinganiselo we-rotor evaliweyo yangoku ukuya kwinqanaba elilinganisiweyo yi-7.0;Xa isantya se-synchronous si-1000, umlinganiselo we-rotor evaliweyo ngoku i-6.5;xa isantya se-synchronous si-750, umlinganiselo we-rotor evaliweyo ngoku i-6.0 yangoku.Amandla e-motor ye-5.5kW makhulu kakhulu, kwaye i-motor enamandla amancinci ngumlinganiselo wesiqalo sangoku ukuya kwi-rated current.Kufuneka ibe yincinci, ngoko ke iincwadi zezifundo zombane kunye neendawo ezininzi zithi ukuqala ngoku kwemoto ye-asynchronous yi-4 ~ 7 amaxesha okusebenza ngoku..

Kutheni le nto injini iqala ngoku iphezulu?Emva kokuqala umsinga uncinci?

Apha kufuneka siqonde ngokwembono yomgaqo-siseko wokuqala kunye nomgaqo wokujikeleza kwemoto: xa i-motor induction ikwimo emisiweyo, ukusuka kwindawo yokujonga i-electromagnetic, ifana ne-transformer, kunye ne-stator winding eqhagamshelwe kumandla. unikezelo lulingana ne-coil ephambili ye-transformer , I-valve-circuit rotor winding ilingana ne-short-circuited coil yesibini ye-transformer;uxhulumaniso olungelulo umbane phakathi kwe-stator winding kunye ne-rotor winding kuphela uxhumano lwamagnetic, kwaye i-magnetic flux yenza isiphaluka esivaliweyo nge-stator, i-gap yomoya, kunye ne-rotor core.Ngomzuzu wokuvala, i-rotor ayikajiki ngenxa ye-inertia, kwaye intsimi yamagnetic ejikelezayo inqumla i-rotor windings kwisantya esiphezulu sokusika.-isantya esihambelanayo, ukuze i-rotor windings ibangele amandla aphezulu ombane.Ngoko ke, inani elikhulu lombane lihamba kwi-rotor conductor.Umsinga wombane, lo wangoku uvelisa amandla emagnethi acima umhlaba wemagnethi westator, kanye njengokuqukuqela kwemagnethi yesibini yesiguquli kucima ukuqukuqela kwemagnethi.Ukuze kugcinwe i-flux yasekuqaleni yamagnetic ehambelana ne-voltage yonikezelo lwamandla ngelo xesha, i-stator iyakwandisa ngoku.Ngenxa yokuba i-rotor yangoku inkulu ngeli xesha, i-stator yangoku iphinda inyuke kakhulu, ide ibe phezulu kwi-4 ukuya kwi-7 amaxesha angoku.Esi sisizathu somsinga omkhulu wokuqalisa.Kutheni le nto incinci yangoku emva kokuqalisa: Njengoko isantya semoto sikhula, isantya apho i-stator magnetic field inqumla i-rotor conductor iyancipha, amandla ombane owenziwe kwi-rotor conductor ayancipha, kwaye umsinga kwi-rotor conductor nawo uyancipha, ngoko ke I-stator yangoku isetyenziselwa ukucima i-rotor yangoku eyenziwa Inxalenye yangoku echaphazelekayo yi-magnetic flux nayo iyancitshiswa, ngoko ke i-stator yangoku itshintsha ukusuka kwinkulu ukuya encinci ukuya kwisiqhelo.
