Puas yog lub cav khiav tawm ib lub cav?
Lub cav servo yog lub cav uas tswj cov kev khiav hauj lwm ntawm cov khoom siv hluav taws xob hauv qhov kev pabcuam, thiab yog ib qho kev pabcuam lub cev tsis muaj kev sib kis.
Lub cav servo tswj tau qhov ceev thiab txoj hauj lwm tseeb yog qhov tseeb. Qhov teeb liab qhov hloov ntawm qhov hloov mus rau lub zog thiab ceev kom tsav khoom. Qhov kev pab cuam rotor servo yog tswj los ntawm cov teeb liab tawm tswv yim thiab tuaj yeem tshwm sim sai sai. Nyob rau hauv qhov kev tswj tsis siv neeg, nws siv los ua tus actuator, thiab kuv tau muaj cov yam ntxwv ntawm cov me electromechanical lub sijhawm tas mus li, siab linearity, thiab pib voltage, uas tuaj yeem hloov tau hluav taws xob tau txais kev nkag mus rau cov lus qhia los yog cov zis tshaj tawm ntawm lub cev ncej . Muab faib rau hauv DC thiab AC servo nws tus cwj pwm tseem ceeb ntawm ob pawg kev txhawb siab yog tias thaum lub teeb liab muaj xoom, tsis muaj qhov tshwm sim kev hloov, thiab kev sib hloov ceev tsis sib haum nrog kev nce ntawm lub zog.
Tawm motors yog ib txoj kev qhib ib qho kev sib raug zoo magnetic field t nws tso tawm magnetic teb ncaj qha mus hloov cov hluav taws xob lub zog rau cov neeg kho tshuab zog ntawm txoj kev tawm suab uas tsis tas yuav tsum tau siv cov kev hloov kho nruab nrab. Cov qauv no yuav pom tau hais tias txiav ib lub cav fais fab uas hloov hauv kev khiav tsheb radial. Thiab lub circumference ntawm lub cev yog tsim rau hauv ib txoj kab ncaj nraim. Wherein tus stator yog sib npaug ntawm thawj tus qauv ntawm txoj hlua, thiab lub rotor yog sib npaug rau qib ob ntawm txoj kab khiav tawm, tom qab thawj zaug tam sim no, ntawm qhov thawj thiab theem ob qho chaw hla ciav hlau khiav hauv cov pa nruab nrab, thiab lub zog quab yuam yog tsim los ntawm cov hla mus los ntawm kev sib nqus magnetic field thiab lub nrawm nrab ntawm cov hlau nplaum, uas yog qhov tseeb ntawm kev tawm suab.
Qhov tseeb, linear motors kuj yog ib hom servo motors . Nyob rau hauv kev tshawb xav, tsuav yog muaj kev tawm tswv yim (linear motors feem ntau nrog Hall lossis linear encoder tawm tswv yim) yuav tsum yog qhov system servo. Vim li no, servo motors yuav tsum muab faib ua ob pawg hauv qhov kev txiav txim siab dav: lub cav servo thiab cov servo linear.
Tawm lub cev muaj zog: kev muaj siab, siab rigidity. Piv nrog rau cov qauv kab tsoo tawm (xws li cov ntsia hlau, hluav taws xob kheej kheej), nws yog kev kho-dawb, tab sis tus nqi yog siab. Nws yuav tsum raug siv nyob rau hauv qee qhov chaw uas qhov kev lag luam muaj zog thiab qhov chaw tshwj xeeb, xws li cov kab hluav taws xob ntau ntau.
