Piv nrog asynchronous motors, cov hlau nplaum ruaj khov synchronous motors muaj ntau yam zoo.Cov hlau nplaum ruaj khov synchronous motors muaj ntau yam xws li lub zog muaj zog, zoo tsav muaj peev xwm Performance index, me me, lub teeb yuag, qis kub nce, thiab lwm yam. Nyob rau tib lub sijhawm, lawv tuaj yeem txhim kho qhov zoo ntawm daim phiaj hluav taws xob, muab kev ua si tag nrho. mus rau lub peev xwm ntawm daim phiaj hluav taws xob uas twb muaj lawm, thiab txuag kev nqis peev ntawm daim phiaj hluav taws xob.
Kev sib piv ntawm kev ua haujlwm thiab lub zog
Asynchronous lub cev muaj zog hauv kev ua haujlwm, lub rotor winding kom nqus tau ib feem ntawm lub zog los ntawm daim phiaj excitation, thiaj li hais tias kev noj ntawm daim phiaj fais fab, qhov no ntawm lub hwj chim mus rau qhov kawg tam sim no nyob rau hauv lub rotor winding nyob rau hauv lub tshav kub noj, qhov poob nyiaj rau kwv yees li 20-30% ntawm tag nrho cov poob ntawm lub cev muaj zog, uas ncaj qha ua rau txo qis efficiency ntawm lub cev muaj zog.Rotor excitation tam sim no hloov mus rau stator winding yog inductive tam sim no, yog li tam sim no mus rau hauv stator winding lags qab daim phiaj voltage, uas ua rau txo qis hauv lub zog ntawm lub cev muaj zog.
Tsis tas li ntawd, asynchronous lub cev muaj zog nyob rau hauv lub load yam (= P2 / Pn) < 50%, nws cov kev khiav hauj lwm efficiency thiab kev khiav hauj lwm hwj chim factor poob ho, yog li feem ntau xav kom nws ua hauj lwm nyob rau hauv lub economic cheeb tsam, uas yog, load tus nqi ntawm 75% - 100%.
Cov hlau nplaum ruaj khov synchronous lub cev muaj zog hauv lub rotor embedded nyob rau hauv cov hlau nplaum ruaj khov, cov hlau nplaum ruaj khov los tsim cov rotor magnetic teb, nyob rau hauv ib txwm ua haujlwm, lub rotor thiab stator sib nqus teb synchronous lag luam, tsis muaj induced tam sim no nyob rau hauv lub rotor, tsis muaj rotor kuj poob, Tsuas yog qhov no tuaj yeem txhim kho kev ua haujlwm ntawm lub cev muaj zog los ntawm 4% mus rau 50%.Nyob rau tib lub sij hawm, vim hais tias tsis muaj induction tam sim no excitation nyob rau hauv lub rotor ntawm mus tas li hlau nplaum synchronous lub cev muaj zog, lub stator winding tej zaum yuav purely resistive load, thiaj li hais tias lub hwj chim yam ntawm lub cev muaj zog yuav luag 1. Permanent hlau nplaum synchronous lub cev muaj zog nyob rau hauv tus nqi load. > 20%, nws cov kev khiav hauj lwm efficiency thiab kev khiav hauj lwm lub hwj chim nrog me ntsis kev hloov, thiab kev khiav hauj lwm efficiency yog> 80%.
Pib torque
Asynchronous lub cev muaj zog pib, lub cev muaj zog yuav tsum muaj qhov loj txaus pib torque, tab sis cia siab tias qhov pib tam sim no tsis loj heev, thiaj li tsis ua kom muaj hluav taws xob ntau dhau ntawm daim phiaj thiab cuam tshuam rau kev ua haujlwm ib txwm ntawm lwm lub cev muaj zog thiab cov khoom siv hluav taws xob txuas nrog. mus rau daim phiaj.Tsis tas li ntawd, thaum pib tam sim no loj dhau lawm, lub cev muaj zog nws tus kheej yuav raug cuam tshuam rau hluav taws xob ntau dhau, yog tias feem ntau pib, muaj qhov txaus ntshai ntawm overheating lub windings.Yog li ntawd, asynchronous lub cev muaj zog pib tsim feem ntau ntsib teeb meem.
Cov hlau nplaum ruaj khov synchronous lub cev muaj zog kuj tseem tuaj yeem siv asynchronous pib hom, vim yog cov hlau nplaum ruaj khov synchronous lub cev muaj zog ib txwm ua haujlwm ntawm lub rotor winding tsis ua haujlwm, hauv kev tsim cov hlau nplaum ruaj khov lub cev muaj zog, rotor winding tuaj yeem ua kom tau raws li qhov yuav tsum tau ua. siab pib torque, piv txwv li, thiaj li hais tias qhov pib torque multiplier los ntawm lub asynchronous lub cev muaj zog 1.8 npaug rau 2.5 zaug, los yog ntau dua, ib qho kev daws teeb meem zoo dua rau cov khoom siv fais fab, Nws daws tau qhov tshwm sim ntawm "cov nees loj rub lub tsheb me me.t” nyob rau hauv cov khoom siv fais fab.
Kev ua haujlwmkub nce
Raws li lub asynchronous lub cev muaj zog ua hauj lwm, lub rotor winding tam sim no ntws, thiab qhov tam sim no yog kiag li nyob rau hauv daim ntawv ntawm thermal zog noj, yog li nyob rau hauv lub rotor winding yuav tsim ib tug loj npaum li cas ntawm tshav kub, thiaj li hais tias qhov kub ntawm lub cev muaj zog nce, uas cuam tshuam loj heev. kev pab cuam lub neej ntawm lub cev muaj zog.
Raws li cov hlau nplaum ruaj khov synchronous lub cev muaj zog, vim qhov ua tau zoo ntawm cov hlau nplaum ruaj khov lub cev muaj zog, tsis muaj qhov tsis kam poob hauv lub rotor winding, muaj tsawg lossis yuav luag tsis muaj qhov cuam tshuam tam sim no hauv stator winding, kom lub cev muaj zog kub nce qis. , uas zoo dua ncua kev pab cuam lub neej ntawm lub cev muaj zog.
Kev cuam tshuam ntawm kev ua haujlwm ntawm daim phiaj
Vim yog lub zog qis ntawm asynchronous lub cev muaj zog, lub cev muaj zog yuav tsum tau nqus ntau cov reactive tam sim no los ntawm daim phiaj hluav taws xob, yog li ua rau muaj ntau cov reactive tam sim no nyob rau hauv daim phiaj fais fab, kis tau tus mob thiab transformation cov cuab yeej thiab cov khoom siv hluav taws xob, yog li ua. Qhov zoo tshaj plaws ntawm daim phiaj hluav taws xob txo qis, uas tsis yog tsuas yog ua rau lub zog ntawm daim phiaj hluav taws xob thiab kev sib kis thiab cov khoom siv hloov pauv thiab cov cuab yeej siv hluav taws xob, tib lub sijhawm, cov khoom siv hluav taws xob tam sim no siv ib feem ntawm cov hluav taws xob hluav taws xob hauv daim phiaj hluav taws xob, kev sib kis thiab cov cuab yeej hloov pauv thiab cov khoom siv hluav taws xob tsim hluav taws xob, ua rau muaj kev ua haujlwm tsawg thiab cuam tshuam rau daim phiaj hluav taws xob.Nyob rau tib lub sijhawm, cov reactive tam sim no siv ib feem ntawm lub zog hluav taws xob hauv daim phiaj hluav taws xob, cov khoom siv sib kis thiab kev hloov pauv thiab cov khoom siv hluav taws xob, uas ua rau lub zog hluav taws xob tsis zoo thiab cuam tshuam rau kev siv hluav taws xob zoo.Ib yam li ntawd, vim tsis muaj kev ua haujlwm zoo ntawm asynchronous motors, kom ua tau raws li qhov xav tau ntawm cov zis hluav taws xob, nws yog ib qho tsim nyog yuav tsum nqus ntau lub zog los ntawm kab sib chaws, yog li ntxiv qhov poob ntawm hluav taws xob hluav taws xob thiab aggravating lub load ntawm daim phiaj.
Thiab rau cov hlau nplaum ruaj khov synchronous lub cev muaj zog, nws cov rotor tsis muaj qhov cuam tshuam tam sim no, lub zog hluav taws xob kuj tseem siab, uas tsis tsuas yog txhim kho qhov zoo ntawm daim phiaj, kom daim phiaj tsis tas yuav nruab cov khoom siv hluav taws xob reactive.Ntxiv mus, vim muaj kev ua haujlwm siab ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog, nws kuj txuag lub zog ntawm daim phiaj.
Anhui Mingteng Permanent-Magnetic Machinery & Hluav Taws Xob Khoom Co., Ltdyog tsim los pab rau xyoo 2007 thiab yog ib lub tuam txhab ua lag luam ntxov tshaj plaws hauv Suav teb los tsim thiab tsim cov hlau nplaum ruaj khov motors.Nws muaj kev paub R & D, ntau lawm, muag, thiab pab pawg tom qab muag.Lub tuam txhab ib txwm ua raws li kev ywj pheej innovation thiab ua raws li txoj cai ntawm "cov khoom lag luam thawj zaug, kev tswj hwm thawj zaug, cov kev pabcuam thawj zaug, thiab cov npe thawj zaug", tailoring ntse ntse hlau nplaum lub cev muaj zog lub zog-txuag tag nrho cov kev daws teeb meem rau cov neeg siv. , thiab siv zog los ua tus thawj coj thiab tus txheej txheem setter nyob rau hauv Tuam Tshoj lub ntiaj teb tsis tshua muaj hlau nplaum lub cev muaj zog kev lag luam.
