Zvichida, mafeni emhando yendege haazove asina kujairana negiya rekutungamirira. RC Servo giya inoita basa rakakosha mumhando yendege, kunyanya mumhando dzendege dzemapapiro uye mhando dzengarava. Kutungamira, kusimuka uye kumhara kwendege kunofanirwa kudzorwa negiya rekutungamirira. Mapapiro anotenderera mberi uye kumashure. Izvi zvinoda kudhonza kweiyo servo mota giya.
Servo mota dzinozivikanwawo se micro servo motors. Chimiro chegiya rekutungamira chiri nyore. Kazhinji kutaura, ine diki DC mota (motor diki) uye seti yemagiya ekudzikisa, pamwe ne potentiometer (yakabatana negiya rekudzikisira kuti riite se sensor yenzvimbo), control circuit board ( Kazhinji inosanganisira voltage comparator uye kuisa. chiratidzo, magetsi).
Servo Yakasiyana kubva pamusimboti we stepper mota, inonyatso sisitimu inoumbwa neDC mota uye akasiyana zvinhu. Iyo stepper mota inovimba neiyo stator coil kuti iwane simba kuti igadzire magineti kukwezva inogara magineti rotor kana kuita pane kusada core stator kutenderera kune yakatarwa chinzvimbo. Muchidimbu, kukanganisa kudiki kwazvo, uye kazhinji hapana kudzora mhinduro. Simba reiyo mini servo mota yegiya rekutungamirira rinobva kuDC mota, saka panofanira kunge paine controller inotumira mirairo kuDC mota, uye kune mhinduro yekutonga mugiya rekutungamirira.
Iyo inobuda giya yeboka rekudzikisira giya mukati megiya rekutungamirira yakanyatsobatanidzwa ne potentiometer kuti igadzire nzvimbo sensor, saka kona yekutenderera yeiyi giya rekutungamirira inokanganiswa nekona yekutenderera ye potentiometer. Migumo miviri yeiyi potentiometer yakabatana nematanda akanaka uye asina kunaka emagetsi ekupinza, uye kuguma kwekutsvedza kwakabatana kune shaft inotenderera. Iwo masaini anoiswa pamwe chete mumagetsi comparator (op amp), uye magetsi eiyo op amp anogumiswa kune yekupinza magetsi. Iyo yekupinza yekudzora chiratidzo chiratidzo che pulse wide modulated signal (PWM), inoshandura avhareji yevoltage nechikamu cheiyo yakakwira voltage munguva yepakati. Iyi yekuisa voltage comparator.
Nekuenzanisa avhareji yevoltage yechiratidzo chekuisa nevoltage yenzvimbo yemagetsi sensor, semuenzaniso, kana magetsi ekupinza akakwira kupfuura chinzvimbo sensor voltage, iyo amplifier inoburitsa yakanaka magetsi ekupa magetsi, uye kana magetsi ekupinza akakwira kupfuura. iyo chinzvimbo sensor voltage, iyo amplifier inoburitsa yakashata magetsi emagetsi, kureva, reverse voltage. Izvi zvinodzora kutenderera uye kudzosera kumashure kutenderera kweDC mota, uye yobva yadzora kutenderera kwegiya rekutungamirira kuburikidza nekubuda kwekudzikisa giya. Sezvakangoita mufananidzo uri pamusoro. Kana iyo potentiometer isina kusungwa kune inobuda giya, inogona kusanganiswa nemamwe mashaft egiya rekudzikisa giya rakaiswa kuti riwane yakafara giya rekufambisa senge 360 ° kutenderera nekudzora chiyero chegiya, uye izvi zvinogona kukonzera hombe, asi kwete. kukanganisa kukanganisa (kureva, kukanganisa kunowedzera nekona yekutenderera).
Nekuda kwechimiro chayo chakareruka uye mutengo wakaderera, giya rekutungamirira rinoshandiswa muzviitiko zvakawanda, kwete chete kuenzanisira ndege. Inoshandiswawo muakasiyana marobhoti maoko, marobhoti, kure kure ekudzora mota, drones, smart dzimba, maindasitiri otomatiki uye mamwe minda. Zviito zvakasiyana-siyana zvemuchina zvinogona kuitika. Kune zvakare yakakosha yakakwirira-torque uye yakakwirira-chaiyo servos yekushandiswa muminda ine yakakwira chaiyo zvinodiwa kana minda inoda torque yakakura uye mitoro mikuru.
