2. Nce rau hauv hom teeb liab tsim nyog rau kev tswj thiab kev ua kom nrov
Hluav taws xob actuators feem ntau ua haujlwm tau zoo nyob rau hauv qee qhov kev tswj cov cim los ntawm kev tsav tsheb fais fab. Nyob rau hauv xyoo tas los no, nrog rau kev hloov kho tshiab ntawm kev ua haujlwm ntawm hluav taws xob actuators, hom teeb liab tsim nyog rau kev tswj thiab kev nthuav dav kuj tau nce sai heev. Yav dhau los, feem ntau cov actuators tsuas yog tswj tau DC cov cim, tab sis tam sim no, txawm tias nws yog DC, AC lossis Ob qho tib si shortwave thiab mem tes signals tuaj yeem nthuav dav thiab nco.
