Qhov zoo thiab qhov tsis zoo ntawm DC servo motors, AC servo motors thiab stepper motors
Yuav kom hloov tau txoj kev loj hlob ntawm cov kev tswj, kev tsav tsheb, kev tsav tsheb DC, lossis tag nrho cov digital AC servo motor feem ntau siv los ua kev tsav lub zog hauv kev tswj xyuas lub zog. Txawm hais tias peb qhov no zoo sib xws, muaj qhov sib txawv hauv kev ua tau zoo thiab daim ntawv thov. Tam sim no Dalan Motor Xiaobian sib piv qhov zoo ntawm peb.
AC servo tsav
zoo dua:
(1) Tsis muaj txhuam thiab commutators, yog li kev ua hauj lwm yog ntseeg tau thiab kev tu vaj tse thiab txij nkawm tsis qis.
(2) Lub stator winding heat dissipation yog yooj yim.
(3) Cov kab no me me, uas yog ib qho yooj yim los txhim kho qhov kev ua haujlwm ntawm cov txheej txheem.
(4) Kho cov kev kub ceev thiab kev ua hauj lwm loj zog.
DC servo lub cev
zoo dua:
DC servo motor yog hais txog DC lub khauj khaum kev tsav tsheb - cov nqi qis zog, cov qauv kev lag luam, lub dav hlau pib, kev ceev dav, kev tswj yooj yim, kev kho, tab sis tsis zoo (hloov hliv carbon), electromagnetic cuam tshuam. Qhov chaw no yuav tsum muaj. Nws thiaj li siv tau rau cov nqi hluav taws xob ntau thiab cov ntaub ntawv thaj chaw nyob.
DC servo motor tsis suav DC brushless servo lub cev - lub cav me me loj, lub teeb nyob rau hauv qhov hnyav, loj hauv cov zis, ua teb ceev ceev, me ntsis hauv inertia, du hauv rotation, ruaj khov hauv torque, thiab txwv hauv lub cev muaj zog hwj chim. Nws yog qhov yooj yim kom paub qhov txawj ntse, thiab nws qhov kev sib txuam hluav taws xob yog hloov tau yooj yim, thiab nws muaj peev xwm muab commutated los ntawm square wave los yog sine wave. Tsav tsheb tsis pub muaj, tsis muaj cov tsoo roj, kev ua haujlwm siab, ua haujlwm tsawg, tsis tshua muaj suab nrov, tshuab hluav taws xob me me, lub neej ntev, thiab siv tau rau ntau qhov chaw.
siv:
(1) Actuator tsav nyob rau hauv ntau lub digital tswj tshuab.
(2) Fais fab tsav uas yuav tsum tau tswj kom ncaj ruaj ntawm qhov ceev ceev los yog kev tswj ntawm qhov kev hloov ceev ceev.
Raws li lub cev muaj zog inertia tau muab faib ua:
(1) Me me inertia DC motor - tsis siv neeg lub tshuab drilling rau cov ntawv cog lus Circuit Court
(2) Medium inertia DC motor (dav ceev DC motor) - kev pub cov ciaj ciam ntawm CNC tshuab
(3) Loj inertia DC lub cev muaj zog - ntxaiv lub cav ntawm cov tshuab CNC tshuab
(4) Daim ntawv tshwj xeeb uas tsis tshua muaj zog hauv DC
Stepper tsav
zoo dua:
(1) Lub kaum sab xis ntawm lub cev muaj zog yog proportional rau pes tsawg tus pulses;
(2) Lub siab tshaj plaws yog muaj thaum lub cav nres (thaum lub cua daj cua dub);
(3) Vim tias cov kauj ruam ntawm txhua kauj ruam yog li ntawm 3% thiab 5%, thiab qhov yuam kev ntawm ib kauj ruam yog tsis sau rau cov kauj ruam tom ntej, nws muaj qhov zoo dua qhov chaw nyob thiab rov ua dua ntawm qhov kev tshwm sim;
(4) Pib zoo thiab nres thiab rov qab teb;
(5) Txij li thaum tsis muaj txhuam, qhov kev cia siab yog siab, yog li lub neej ntawm lub tshuab nyob ntawm lub neej ntawm kev coj;
(6) Cov lus teb ntawm lub tshuab yog txiav txim siab tsuas yog los ntawm digital input pulse, thiaj qhib loop tswj tau siv tau, uas ua rau tus qauv ntawm lub tshuab kuj yooj yim thiab tswj tus nqi;
(7) Nws tseem tuaj yeem ncaj qha mus ncaj nraim kom thauj khoom ncaj nraim mus rau lub nrig ntawm lub cav kom qis qis;
(8) Txij li thaum kev khiav ceev yog proportional mus rau lub sijhawm muaj mem tes, nws muaj qee kis dav dav.
kho raws:
(1) Yog tias qhov kev tswj tsis zoo, nws yuav yooj yim rau tsim cov resonance;
(2) Nws tsis yooj yim rau khiav ceev dua;
(3) Nws yog ib qho nyuaj rau tau txais ib qho loj torque;
(4) Tsis muaj qhov zoo ntawm qhov ntim thiab qhov hnyav, thiab kev siv hluav taws xob tsawg tsawg;
(5) Thaum twg tus load exceeded, synchronization puas lawm, thiab kev co thiab suab nrov yog generated ntawm kev kub ceev.
Hauv cov ntsiab lus, lub AC servo system yog superior ntawm lub cav ntu theem hauv ntau qhov kev ua haujlwm. Txawm li cas los xij, nyob rau qee lub sijhawm twg qhov kev xav tsis siab, stepper motors feem ntau siv los ua lub tshuab. Yog li ntawd, nyob rau hauv tus txheej txheem tsim ntawm kev tswj, nws yog ib qho tseem ceeb rau kev xav txog kev tswj cai, tus nqi thiab lwm yam, thiab xaiv txoj kev tswj xyuas kev tsav tsheb.
