Kucingelwa ukuba, abalandeli bemodeli yenqwelomoya abayi kuqhelana nezixhobo zokuqhuba. Izixhobo zeRC Servo zidlala indima ebalulekileyo kwimodeli yenqwelomoya, ngakumbi kwiimodeli zenqwelomoya ezinamaphiko kunye neemodeli zeenqanawa. Ukuqhuba, ukunduluka kunye nokuma kwenqwelo-moya kufuneka kulawulwe ngesixhobo sokuqhuba. Amaphiko ajikeleza phambili kwaye abuyele umva. Oku kufuna ukutsalwa kwesixhobo se-servo motor.
Iinjini zeServo zikwabizwa ngokuba ziimotor ezincinci ze-servo. Ubume besixhobo sokuqhuba silula. Ngokuqhelekileyo, iqulethe i-motor encinci ye-DC (imoto encinci) kunye neseti yeegiya zokunciphisa, kunye ne-potentiometer (edityaniswe kwisinciphisi segiya ukuze isebenze njengenzwa yendawo), ibhodi yesekethe yokulawula ( Ngokubanzi ibandakanya umlinganisi wombane kunye nomqondiso wegalelo, ukunikezelwa kwamandla).
I-Servo Yahlukile kumgaqo we-stepper motor, ngokusisiseko yinkqubo eyenziwe yi-DC motor kunye nezinto ezahlukeneyo. I-stepper motor ixhomekeke kwi-coil ye-stator ukuba inikwe amandla okuvelisa i-magnetic field ukutsala i-rotor yemagnethi esisigxina okanye isebenze kwi-stator engundoqo yokungafuni ukujikeleza kwindawo echaziweyo. Ngokwenyani, impazamo incinci kakhulu, kwaye akukho lulawulo lwempendulo ngokubanzi. Amandla e-mini servo motor ye-steering gear avela kwi-motor ye-DC, ngoko kufuneka kubekho umlawuli othumela imiyalelo kwi-motor ye-DC, kwaye kukho ulawulo lwempendulo kwindlela yokulawula.
Isixhobo esiphumayo seqela lokunciphisa igiya ngaphakathi kwesixhobo sokuqhuba sidityaniswe ne-potentiometer ukwenza i-sensor yesikhundla, ngoko ke i-angle yokujikeleza yale gear yokulawula ichaphazeleka yi-angle yokujikeleza ye-potentiometer. Zomibini iziphelo zale potentiometer zixhunywe kwiipali ezilungileyo kunye nezibi zonikezelo lwamandla okufakwayo, kwaye isiphelo se-sliding sixhunyiwe kwi-shaft ejikelezayo. Iimpawu zifakwe kunye kwi-comparator ye-voltage (op amp), kunye nokunikezelwa kwamandla e-op amp kupheliswe kwi-input power comparator. Isiginali yokulawula igalelo yi-pulse width modulated signal (PWM), etshintsha i-voltage ye-avareji ngomlinganiselo we-voltage ephezulu kwixesha eliphakathi. Esi sithelekisi sombane wegalelo.
Ngokuthelekisa umndilili wombane wesixhobo sokufaka umbane kunye nombane wesixhobo senzwa yombane, umzekelo, ukuba igalelo lombane liphezulu kunevoltheji ye-sensor yesikhundla, i-amplifier ikhupha amandla ombane afanelekileyo, kwaye ukuba igalelo lombane liphezulu kunendawo yombane we-sensor sensor, iamplifier ikhupha umbane ongalunganga wonikezelo lwamandla, oko kukuthi, umbane obuyela umva. Oku kulawula ukujikeleza phambili kunye nokubuyisela umva kwemoto ye-DC, kwaye ilawula ukujikeleza kwesixhobo sokuqhuba ngeseti yokunciphisa imveliso. Kanye njengomfanekiso ongentla. Ukuba i-potentiometer ayibotshwanga kwigiya yokuphuma, inokudityaniswa nezinye iishafti zeseti yokunciphisa igiya ukufikelela kuluhlu olubanzi lweegiya zokuqhuba ezinje nge-360 ° ukujikeleza ngokulawula umlinganiselo wegiya, kwaye oku kunokubangela ukuba kukhulu, kodwa akukho mpazamo yokongezelekayo (okt, impazamo yonyuka nge-engile yokujikeleza).
Ngenxa yobume bayo obulula kunye neendleko eziphantsi, izixhobo zokuqhuba zisetyenziswa ngamaxesha amaninzi, azipheleli nje kwimodeli yenqwelomoya. Ikwasetyenziswa kwiingalo ezahlukeneyo zerobhothi, iirobhothi, iimoto ezikude, iidrones, amakhaya ahlakaniphileyo, i-automation yemizi-mveliso kunye namanye amasimi. Iintshukumo ezahlukeneyo zoomatshini zinokufezekiswa. Kukho ii-servos ezikhethekileyo eziphezulu kunye ne-high-precision servos ukuze zisetyenziswe kwiindawo ezineemfuno ezichanekileyo okanye iindawo ezifuna i-torque enkulu kunye nemithwalo emikhulu.
