Servo lub cev muaj zog yog lub cav uas tswj kev ua haujlwm ntawm cov khoom siv hauv lub tshuab servo. Nws yog ib qho kev pab lub cev muaj zog indirect kis tau tus mob. Lub servo lub cev muaj zog tuaj yeem tswj tau qhov ceev, qhov tseeb ntawm txoj hauj lwm yog qhov tseeb heev, tuaj yeem hloov cov teeb liab voltage rau hauv lub torque thiab qhov ceev kom tsav cov khoom tswj. Servo lub cev muaj zog rotor ceev yog tswj los ntawm cov teeb liab tawm tswv yim, thiab tuaj yeem teb tau sai, hauv kev tswj tsis siv neeg, raws li kev tswj hwm, thiab muaj lub sijhawm me me ntawm electromechanical tsis tu ncua, siab linearity, pib voltage thiab lwm yam ntxwv, lub teeb liab tau txais hluav taws xob tuaj yeem ua tau. hloov mus rau hauv lub cev muaj zog ncej angular displacement los yog angular ceev tso zis. Nws tuaj yeem muab faib ua dc servo motors thiab ac servo motors. Nws cov yam ntxwv tseem ceeb yog tias thaum lub teeb liab voltage yog xoom, tsis muaj qhov tshwm sim ntawm kev sib hloov, thiab qhov nrawm nrawm nrog qhov nce ntawm lub zog.

Servo motors yog dav siv nyob rau hauv ntau yam kev tswj systems, uas yuav hloov lub input voltage teeb liab mus rau txhua yam tso zis ntawm lub cev muaj zog ncej thiab luag cov tswj Cheebtsam kom ua tiav lub hom phiaj ntawm kev tswj.

Muaj dc thiab ac servo motors; Qhov ntxov tshaj plaws servo lub cev muaj zog yog dav dav dc lub cev muaj zog, nyob rau hauv kev tswj ntawm qhov tseeb tsis siab, kev siv lub dav dav dc lub cev muaj zog los ua servo lub cev muaj zog. Tam sim no dc servo lub cev muaj zog yog lub zog qis dc lub cev muaj zog hauv cov qauv, thiab nws cov excitation feem ntau yog tswj los ntawm armature thiab magnetic teb, tab sis feem ntau yog armature tswj.

Kev faib tawm ntawm kev sib hloov lub cev muaj zog, dc servo lub cev muaj zog nyob rau hauv cov yam ntxwv ntawm cov neeg kho tshuab tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov kev tswj hwm, tab sis vim tias muaj cov commutator, muaj ntau yam tsis txaus: commutator thiab txhuam ntawm yooj yim los tsim sparks, cuam tshuam tus neeg tsav tsheb ua haujlwm, tsis tuaj yeem. yuav siv tau nyob rau hauv cov ntaub ntawv ntawm flammable gas; Muaj kev sib txhuam ntawm txhuam thiab commutator, uas ua rau muaj qhov chaw tuag loj.

Cov qauv yog complex thiab txij nkawm yog nyuaj.

Ac servo lub cev muaj zog yog qhov tseem ceeb ntawm ob-theem asynchronous lub cev muaj zog, thiab feem ntau muaj peb txoj kev tswj hwm: amplitude tswj, theem tswj thiab amplitude tswj.

Feem ntau, servo lub cev muaj zog yuav tsum muaj lub cev muaj zog kom tswj tau los ntawm cov teeb liab voltage; Kev sib hloov ceev tuaj yeem hloov tsis tu ncua nrog kev hloov ntawm qhov hluav taws xob teeb liab. Cov lus teb ntawm lub cev muaj zog yuav tsum ceev ceev, lub ntim yuav tsum me me, lub zog tswj yuav tsum me me. Servo motors feem ntau yog siv nyob rau hauv ntau yam kev tswj lub cev, tshwj xeeb tshaj yog cov servo system.
