Yam ntxwv thiab txoj cai ntawm servo lub cev
Lub cav servo yuav tswj tau nyob rau hauv peb hom kev torque, txoj hauj lwm thiab kev ceev, thiab tswj tau nyob rau hauv ib lub kaw lus ntxees nrog kev tswj siab heev.Xais tseem ceeb nta: thaum lub teeb liab voltage yog xoom, tsis muaj kev hloov tshwm sim, kev sib hloov ceev decreases tsis tshee nrog kev nce ntawm torque, thiab kev sib hloov hauv inertia me me, uas yuav raug siv rau qhov muab tso rau.
Lub cav servo yuav ua rau kev tswj ceev thiab txoj hauj lwm tseeb meej heev, thiab muaj peev xwm hloov cov teeb liab voltage rau hauv torque thiab kev tsav tsheb cov khoom tswj.Qhov rotor ceev ntawm lub cav servo yog tswj los ntawm lub teeb liab, thiab tuaj yeem mob ceev nrooj. Nyob hauv qhov kev tswj tsis siv neeg, nws yog siv los ua tus thawj tswj, thiab muaj cov yam ntxwv ntawm cov me electromechanical lub sijhawm tas mus li, siab linearity thiab pib voltage, uas tuaj yeem hloov tau cov hluav taws xob tau txais kev nkag mus rau hauv kev xaav ceev lossis qhov tshaj tawm ntawm lub cev lub cev.Nws muab faib ua ob hom: dc thiab ac servo motors. Nws lub ntsiab feature yog tias thaum lub teeb liab voltage yog xoom, tsis muaj kev sib hloov, thiab qhov kev txo qis tsis muaj qhov nce ntawm torque.
Cov cwj pwm thiab txoj cai ntawm lub zog ntawm lub cev
Torque tsav yog ib hom tsav nrog torque raws li kev tswj kev tswj thiab qhib voj tswj hom. Nws yog ib qho tshwj xeeb lub cev muaj zog nrog cov yam ntxwv ntawm cov neeg kho tshuab thiab cov dav dav. Nws muaj tsawg ceev, siab torque, muaj zog muaj zog dua, muaj lus teb ceev thiab zoo tus cwj pwm linearity.Itsws nta tseem ceeb raws li nram no: nws muaj cov khoom kho tshuab muag khoom thiab nres lub torque. Thaum twg qhov load torque tsub kom, nws tuaj yeem txo qhov kev sib hloov ntawm kev sib hloov thiab nce zis qhov hluav taws xob tib lub sijhawm.
