Cishe, abalandeli bezindiza eziyimodeli ngeke bangazi lutho ngegiya lokuqondisa. Igiya le-RC Servo lidlala indima ebalulekile endizeni eyimodeli, ikakhulukazi kumamodeli wezindiza ezinamaphiko angashintshi kanye namamodeli emikhumbi. Isiteringi, ukusuka kanye nokuma kwendiza kufanele kulawulwe yigiya lokuqondisa. Amaphiko azungeza phambili futhi ahlehle. Lokhu kudinga ukudonsa kwegiya le-servo motor.
Ama-Servo motors ayaziwa nangokuthi ama-micro servo motors. Isakhiwo segiya lokuqondisa silula. Ngokuvamile, iqukethe injini encane ye-DC (injini encane) kanye nesethi yamagiya okunciphisa, kanye ne-potentiometer (exhunywe kusinciphisi segiya ukuze isebenze njengenzwa yendawo), ibhodi lesifunda sokulawula ( Imvamisa ihlanganisa isiqhathanisi sikagesi nokokufaka. isignali, ukunikezwa kwamandla).
I-Servo Ihlukile kumgomo we-stepper motor, empeleni iwuhlelo olwakhiwe yi-DC motor kanye nezingxenye ezahlukahlukene. I-stepper motor incike kukhoyili ye-stator ukuthi inikwe amandla ukuze ikhiqize inkambu kazibuthe ukuze ihehe irotha kazibuthe ehlala njalo noma isebenze ku-stator ewumgogodla wokungabaza ukuze ijikelezise endaweni ethile. Empeleni, iphutha lincane kakhulu, futhi ngokuvamile akukho ukulawulwa kwempendulo. Amandla emoto encane ye-servo yegiya lokuqondisa avela ku-DC motor, ngakho-ke kufanele kube nesilawuli esithumela imiyalo ku-DC motor, futhi kube nokulawulwa kwempendulo ohlelweni lwegiya lokuqondisa.
Igiya eliphumayo leqembu legiya lokwehlisa ngaphakathi kwegiya lokuqondisa lixhunywe ne-potentiometer ukuze kwakhe inzwa yendawo, ngakho-ke i-engeli yokuzungeza yaleli giya lokuqondisa ithintwa i-engeli yokuzungeza ye-potentiometer. Zombili iziphetho zale potentiometer zixhunywe ezigxotsheni ezinhle nezingezinhle zokunikezwa kwamandla okokufaka, futhi ukuphela kokuslayida kuxhunywe ku-shaft ejikelezayo. Amasiginali afakwa ndawonye abe isiqhathanisi se-voltage (op amp), futhi ukunikezwa kwamandla kwe-op amp kuyanqanyulwa ekunikezeni amandla okokufaka. Isignali yokulawula okokufaka iyisiginali eguquliwe yobubanzi be-pulse (PWM), eshintsha i-voltage emaphakathi ngenani lamandla kagesi aphezulu esikhathini esimaphakathi. Lesi sifanisi se-voltage okokufaka.
Ngokuqhathanisa i-voltage emaphakathi yesiginali yokufaka ne-voltage yenzwa yendawo yamandla, isibonelo, uma i-voltage yokufaka ingaphezulu kwe-voltage yenzwa yendawo, i-amplifier ikhipha i-voltage yokuphakelwa kwamandla, futhi uma i-voltage yokufaka ingaphezulu i-voltage yenzwa yokuma, i-amplifier ikhipha i-voltage yokuphakelwa kwamandla engalungile, okungukuthi, i-voltage ehlehlayo. Lokhu kulawula ukuzungeza phambili nokuhlehla kwemoto ye-DC, bese kulawula ukuzungezisa kwegiya lokuqondisa ngesethi yegiya lokunciphisa okukhiphayo. Njengesithombe esingenhla. Uma i-potentiometer ingaboshelwe egiyeni elikhiphayo, ingahlanganiswa namanye ama-shaft egiya lokunciphisa isethi ukuze kuzuzwe uhla olubanzi lwegiya lokuqondisa elinjengokuzungezisa okungu-360 ° ngokulawula isilinganiso segiya, futhi lokhu kungase kubangele okukhulu, kodwa cha iphutha elikhulayo (okungukuthi, iphutha liyakhula nge-engeli yokuzungezisa).
Ngenxa yesakhiwo sayo esilula nezindleko eziphansi, igiya lokuqondisa lisetshenziswa ezikhathini eziningi, akugcini nje kuphela kumamodeli endiza. Ibuye isetshenziswe ezingalweni ezihlukahlukene zamarobhothi, amarobhothi, izimoto ezilawula kude, ama-drones, amakhaya ahlakaniphile, i-automation yezimboni neminye imikhakha. Izenzo ezihlukahlukene zemishini zingenziwa. Kukhona futhi ama-servos akhethekile ane-torque ephezulu kanye ne-high-nemba ukuze asetshenziswe emasimini anezidingo zokunemba okuphezulu noma amasimu adinga i-torque enkulu nemithwalo emikhulu.
