Mwinamwake, mafani a ndege zachitsanzo sadzakhala achilendo ndi zida zowongolera.Zida za RC Servo zimagwira ntchito yofunika kwambiri mu ndege zachitsanzo, makamaka pazithunzi za ndege zamapiko osasunthika ndi masitima apamtunda.Kuwongolera, kunyamuka ndi kutera kwa ndege kuyenera kuyendetsedwa ndi zida zowongolera.Mapiko amazungulira kutsogolo ndi kumbuyo.Izi zimafuna mphamvu yamagetsi ya servo motor.
Ma Servo motors amadziwikanso kuti ma micro servo motors.Mapangidwe a zida zowongolera ndizosavuta.Nthawi zambiri, imakhala ndi injini yaying'ono ya DC (motor yaying'ono) ndi zida zochepetsera, kuphatikiza potentiometer (yolumikizidwa ndi chochepetsera giya kuti igwire ntchito ngati sensa yamagawo), bolodi yowongolera ( Nthawi zambiri imaphatikizanso kufananizira voteji ndi zolowetsa. chizindikiro, magetsi).
Servo Mosiyana ndi mfundo ya stepper motor, kwenikweni ndi makina opangidwa ndi DC motor ndi zida zosiyanasiyana.The stepper motor imadalira koyilo ya stator kuti ikhale ndi mphamvu kuti ipangitse mphamvu ya maginito kuti ikope rotor yokhazikika ya maginito kapena kuchitapo kanthu pa stator yapakatikati kuti izungulire kumalo enaake.Kwenikweni, cholakwikacho ndi chaching'ono kwambiri, ndipo nthawi zambiri palibe kuwongolera mayankho.Mphamvu ya mini servo motor ya giya chiwongolero imachokera ku mota ya DC, kotero payenera kukhala wowongolera yemwe amatumiza malamulo ku mota ya DC, ndipo pamakhala kuwongolera mayankho pamakina owongolera.
Zida zotulutsa za gulu la zida zochepetsera mkati mwa zida zowongolera zimalumikizidwa kwenikweni ndi potentiometer kuti apange sensor yamalo, kotero mbali yozungulira ya zida zowongolera izi imakhudzidwa ndi kozungulira kwa potentiometer.Mapeto onse a potentiometer awa amalumikizidwa ndi mizati yabwino komanso yoyipa yamagetsi olowera, ndipo mapeto otsetsereka amalumikizidwa ndi shaft yozungulira.Zizindikirozo zimalowetsedwa palimodzi mu comparator yamagetsi (op amp), ndipo mphamvu ya op amp imathetsedwa kumagetsi olowera.Chizindikiro chowongolera cholowetsa ndi pulse wide modulated sign (PWM), yomwe imasintha ma voltage apakati ndi gawo lamagetsi apamwamba munthawi yapakatikati.Izi zofananira voteji.
Poyerekeza pafupifupi voteji ya siginecha yolowera ndi voteji ya sensa yamphamvu, mwachitsanzo, ngati voteji yolowera ndi yayikulu kuposa voteji ya sensor sensor, amplifier imatulutsa voteji yabwino, ndipo ngati voteji yolowera ndi yayikulu kuposa voteji ya sensor sensor, amplifier imatulutsa voteji yoyipa, ndiye kuti, reverse voteji.Izi zimayendetsa kutsogolo ndi kumbuyo kwa injini ya DC, kenako ndikuwongolera kuzungulira kwa zida zowongolera kudzera mu seti yochepetsera zotulutsa.Monga chithunzi pamwambapa.Ngati potentiometer siyimangika ku zida zomwe zimatulutsa, imatha kuphatikizidwa ndi ma shaft ena a zida zochepetsera kuti mukwaniritse zida zowongolera monga 360 ° kuzungulira powongolera kuchuluka kwa zida, ndipo izi zitha kuyambitsa zazikulu, koma ayi. kulakwitsa kochulukira (mwachitsanzo, cholakwika chimawonjezeka ndi kozungulira).
Chifukwa cha mawonekedwe ake osavuta komanso otsika mtengo, zida zowongolera zimagwiritsidwa ntchito nthawi zambiri, osati kungoyerekeza ndege.Amagwiritsidwanso ntchito m'manja osiyanasiyana amaloboti, maloboti, magalimoto owongolera kutali, ma drones, nyumba zanzeru, makina opanga mafakitale ndi magawo ena.Zochita zosiyanasiyana zamakina zimatha kuchitika.Palinso ma servos apadera okwera kwambiri komanso olondola kwambiri kuti agwiritsidwe ntchito m'minda yomwe ili ndi zofunikira kwambiri kapena minda yomwe imafunikira torque yayikulu ndi katundu wamkulu.
