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.Ngokubanzi, ibandakanya i-motor encinci ye-DC (imoto encinci) kunye neseti yeegiya zokunciphisa, kunye ne-potentiometer (eqhagamshelwe kwisinciphisi segiya ukuze isebenze njengenzwa yesikhundla), ibhodi yesekethe yolawulo ( Ngokubanzi ibandakanya isilinganisi sombane kunye negalelo. uphawu, unikezelo lwamandla).
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 leegiya zokunciphisa ngaphakathi kwisixhobo 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 amandla ombane kunye nombane wesixhobo soluvo sombane, umzekelo, ukuba amandla ombane egalelo angaphezulu kunendawo yombane wesivamvo, iamplifier ikhupha amandla ombane alungileyo, kwaye ukuba amandla ombane ogalelo angaphezulu Umbane woluvo lwendawo, iamplifier ikhupha amandla ombane angalunganga, 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 kwisixhobo sokukhupha, inokudityaniswa nezinye iishafti zeseti yokunciphisa igiya ukufezekisa uluhlu olubanzi lweegiya zokuqhuba ezinje nge-360 ° ukujikeleza ngokulawula umlinganiselo wegiya, kwaye oku kunokubangela ukuba kukhulu, kodwa hayi. impazamo eyongezelekayo (okt, impazamo iyanda 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.
