Kev ua tau zoo ntawm cov ntaub ntawv magnet uas nyob ruaj khov
Cov tshuab hluav taws xob khov kho, tshwj xeeb tshaj yog cov uas siv cov khoom tsis tshua zoo hauv lub ntiaj teb, ua rau cov huab cua sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, thiab lub cav qog muaj peev xwm ua tau zoo tshaj plaws. Qhov ncaj nyhuv yog tias lub tshuab txo qis thiab luj yog txo. Tsis tas li ntawd xwb, tab sis kuj yog cov cuab yeej hlau nplaum txuas mus ntxiv thiab muaj kev tswj kom tau zoo dua li lwm cov motors. Qhov no yog vim hais tias: Ua ntej, lub zog torque tas, torque inertia piv, hwj chim ceev, thiab lwm yam. Ntawm lub cev muaj zog zoo dua vim kev kawm siab ntawm lub ntiaj teb tsawg tsawg daim npliag magnet khoom. Los ntawm tsim nyog tsim, cov ciaj ciam xws li lub sij hawm ntawm inertia, hluav taws xob thiab mechanical lub sij hawm tsis tas yuav txo, thiab lub ntsiab qhia ntawm servo tswj kev ua tau zoo heev. Qhov thib ob, nyob rau hauv lub caij nyoog niaj hnub magnet lub cev, qhov tsim ntawm cov hlau nplaum magnet hlau nplaum tau zoo lawm, thiab lub zog quab yuam ntawm lub ntiaj teb tsis tshua muaj hlau nplaum cov khoom muaj siab heev, yog li cov tshuaj tiv thaiv thiab lwm yam kev tsis sib haum xeeb yog zoo heev, thiab lub cev muaj zog Lub hwj xwm tswj tsis tau zoo heev nrog tus cawv ntawm lwm cov teeb meem. Thirdly, txij thaum siv cov nplaum hluav taws xob es tsis txhob siv fais fab, qhov tsim ntawm qhov excitation winding thiab qhov excitation magnetic teb txo, li no txo cov tsis xws li tus excitation flux, excitation winding inductance, thiab lub siab tam sim no, uas ncaj qha txo cov qhob kom muaj peev xwm lossis tsis tau. Combining cov teeb meem saum toj no, nws yuav hais tau tias lub tshuab hlau nplaum ruaj khov muaj kev tswj zoo heev.
Piv txwv, tam sim no cov ntawv magnet AC servo motor muaj kev ceev ceev kev tswj cov kev ua haujlwm, thiab sine wave AC servo motor muaj tus ceev piv ntawm li 1: 100,000. Stepper motors thiab low-speed synchronous motors tau zoo tuaj thiab tsim tawm cov zis lub zog thiab cov lus teb rau dynamic tom qab siv cov khoom siv phom sij mus tas li. Yog li, piv nrog tib lub zog tshwj xeeb, qhov kev ua tau zoo ntawm qhov kev ua haujlwm, kev ua haujlwm nyob rau hauv lub xeev, kev tswj qhov ntsuas thiab kev ntseeg tau ntawm kev ua lag luam uas ruaj khov kho tau zoo dua qub nrog rau qhov qub tsav.
2.3 Kev ua haujlwm tau zoo thiab kev txuag hluav taws xob
Cov tshuab hluav taws xob tsis tu ncua tsis tsuas yog txo qhov kev ua haujlwm tsis tau, tab sis kuj ua rau lub zog tau zoo ntxiv. Piv txwv, cov hlau nplaum synchronous uas muaj peev xwm ua kom muaj peev xwm thiab kev siv zog ntawm qhov 25% mus rau 120% ntawm qhov kev ntsuas ntau. Cov tshuab hluav taws xob micro-txuas ntawm DCW ntawm 300W micro lub cev tshwj xeeb nyob rau hauv 7th qhov teeb meem ntawm 2006 yog 10% ~ 20% ntau dua qhov hluav taws xob excitation lub zog ntawm tib qhov kev qhia. Tom qab kev siv cov kiv cua thiab cov twj siv twj siv twj pauv hloov mus rau cov tshuab hluav taws xob txuas mus tas li, kev txuag hluav taws xob txuag tseem ceeb heev. Qhov ntau dua lub zog, qhov ntau dua qhov kev faib ua feem ntawm kev poob mus rau tag nrho cov poob, yog li qhov zoo ntawm high-efficiency mus tas li magnet motor yog ntau tseem ceeb.
