Dalaivala wa Servo ndi mtundu wa chowongolera chomwe chimagwiritsidwa ntchito kuwongolera kuyenda kwagalimoto, komwe kumatha kuzindikira kuwongolera kolondola kwambiri kwamagalimoto.Imagwira ntchito yofunikira pakugwiritsa ntchito makina, monga ma automation a mafakitale, ma robotiki, ma ndege, zida zamankhwala, magalimoto odziyimira pawokha ndi magawo ena.
Madalaivala a Servo amagwira ntchito posintha ma signature kukhala ma siginecha omwe amawongolera kuyenda kwamagalimoto.Mu servo system, dalaivala amalandira chizindikiro chowongolera kuchokera kwa wowongolera ndikuwongolera zomwe zikuchitika kugalimoto kudzera pa amplifier yapano, pozindikira cholinga chowongolera kuzungulira kwagalimoto.Dalaivala amathanso kuyang'anitsitsa momwe galimoto ikuyendetsedwera ndikupereka zizindikiro kwa wolamulira kuti wolamulirayo athe kusintha zizindikiro zotuluka mu nthawi kuti asunge kulondola ndi kukhazikika kwa kayendetsedwe ka galimoto.
Dalaivala wa Servo amapangidwa ndi control circuit, power circuit ndi feedback circuit.
Control circuit:
Dera lowongolera ndilo gawo lalikulu la driver wa servo, lomwe limapangidwa ndi microprocessor ndi controller.Dongosolo lowongolera limalandira chizindikiro cholamula kuchokera kwa wolamulira wa servo ndikuchisintha kukhala chizindikiro chowongolera chamagetsi oyendetsa, omwe amawongolera kuyenda kwa servo motor ndi machitidwe a zida zotumphukira.
Mphamvu yozungulira:
Mphamvu yozungulira ndi gawo lofunikira la dalaivala wa servo, imayang'anira ma voteji apano ndi linanena bungwe kudzera mu chubu chamagetsi ndi zigawo zina, kuti servo mota molingana ndi zomwe zimafunikira pa liwiro ndi chiwongolero.
Ndemanga zozungulira:
Dera la mayankho limagwiritsidwa ntchito kuti lizindikire momwe injini ya servo ilili ndikudyetsa zomwe zapezeka zenizeni zenizeni kubwerera kudera lowongolera kuti likwaniritse zowongolera zolondola.Dera loyankha limaphatikizapo encoder, Hall element ndi sensor.
Madalaivala a Servo ali ndi zabwino izi:
1. Kulondola kwambiri: Dalaivala wa Servo amatha kukwaniritsa malo olondola kwambiri, kuthamanga, kuwongolera ma torque ndipo amatha kuyendetsa bwino galimotoyo kuti akwaniritse bwino kwambiri.
2. Kuyankha Mwachangu: Dalaivala wa servo ali ndi liwiro lofulumira ndipo amatha kupanga mphamvu yeniyeni ndi kulamulira malo mu nthawi yochepa, motero amakwaniritsa kayendedwe kapamwamba komanso ntchito zodula kwambiri.
3. Wokhazikika komanso wodalirika: Dalaivala wa servo amatenga ukadaulo wowongolera wotsekeka, womwe ungayang'anire malo ndi liwiro la mota munthawi yeniyeni kuti zitsimikizire kukhazikika ndi kudalirika kwagalimoto.
4. Zosiyanasiyana: Dalaivala wa servo amatha kuthandizira njira zosiyanasiyana zowongolera, monga kuwongolera malo, kuwongolera liwiro, kuwongolera ma torque, ndi zina zambiri, komanso amatha kuzindikira ukadaulo wapamwamba wowongolera, monga kuwongolera njira, kuwongolera kwa PID, ndi zina zambiri.
5. Kupulumutsa mphamvu: Servo drive imatha kuzindikira kutembenuka kwamphamvu kwamphamvu, ndipo imakhala ndi ntchito yopulumutsa mphamvu.Ndi kuwongolera kolondola, mphamvu imatha kupulumutsidwa ndikuchepetsa ndalama.
6. Yosavuta komanso yosinthika: dalaivala wa servo ndi wosavuta kusintha ndipo amatha kutengera malo osiyanasiyana ogwirira ntchito ndi zofunikira pakugwiritsa ntchito mwakusintha kosavuta.
7. Zogwiritsidwa ntchito kwambiri: madalaivala a servo amagwiritsidwa ntchito kwambiri pazida zamakina, zida zodzipangira okha, makina osindikizira, makina a nsalu, makina opangira chakudya, zida zamankhwala, mafakitale agalimoto ndi magawo ena.
Makhalidwe apamwamba a servo driver ndi awa:
1. Kuwongolera kolondola: Dalaivala wa Servo amatengera dongosolo lotsekeka, lomwe limatha kuyendetsa bwino liwiro ndi malo agalimoto.
2. Kuthamanga kwachangu: Woyendetsa servo ali ndi makhalidwe othamanga mofulumira komanso kuthamanga kwambiri, zomwe zingathe kukwaniritsa zofunikira za kuyenda mofulumira.
3. Kuwongolera mwatsatanetsatane malo: Dalaivala wa Servo ali ndi mawonekedwe apamwamba kwambiri, amatha kukwaniritsa zofunikira zowongolera malo.
4. Programmable: servo madalaivala akhoza anakonza kukwaniritsa zosiyanasiyana zovuta kuyenda trajectory ulamuliro.
5. Kukhazikika ndi kudalirika: dalaivala wa servo ali ndi kukhazikika bwino ndi kudalirika, ndipo samakonda kulephera pakugwira ntchito kwa nthawi yaitali.
6. Ntchito zambiri: servo drive ingagwiritsidwe ntchito pamitundu yosiyanasiyana yamagalimoto, imatha kukwaniritsa zosowa zamagawo osiyanasiyana ogwiritsira ntchito.
