Iindaba

I-DSPOWER yaqala ngo-2012, igxile kuphando kunye nophuhliso lokuvelisa imfundo yerobhothi, i-servo yerobhothi ekrelekrele kunye neBlock Block servo.

Xa uyila iirobhothi okanye izixhobo ezikrelekrele, ukuchaneka kwe-angular yeemoto ze-servo zihlala zingahoywa ngokulula kodwa ipharamitha ebalulekileyo. Usenokuba udibene neemeko apho i-servo motor iyasilela ukujikeleza kwindawo ekujoliswe kuyo, okanye indawo efikelelwe kuyo iyahluka kancinci ixesha ngalinye, ibangela ukungazinzi kuyo yonke inkqubo.

Oku kungenxa yokuba awukhange uhoye ixabiso le-angular echanekileyo ye-servo motor, kwaye ukhangele kuphela iiparamitha ezisisiseko ezifana ne-torque kunye nesantya.

Yintoni i-Servo Motor Angular Ukuchaneka?

Ukuchaneka kwe-angular ye-Servo kubhekiselele kwiqondo lokutenxa phakathi kwendawo eyiyo yokujikeleza kunye nendawo ekujoliswe kuyo kwithiyori emva kokufumana umqondiso wolawulo. Umzekelo, i-servo motor ene-±1° echanekileyo, ithiyori ijikeleza ukuya kuma-90°, inokubekwa phakathi kwama-89° nama-91°. Eli xabiso lomgangatho wokuchaneka lidla ngokunikezelwa ngumenzi we-servo motor kwiinkcukacha zobugcisa.

Yenye yezalathi ezingundoqo zokulinganisa ukusebenza kweemoto ze-servo. Iinkonzo ezichanekileyo ezichanekileyo ziqinisekisa ukunyakaza okuchanekileyo kunye nokuphindaphindiweyo kwesixhobo sakho, ngakumbi kwiimeko ezifuna ulawulo oluchanekileyo, olunje ngokubamba ingalo yerobhothi kunye nokuma kwekhamera yegimbal.

Ukuqonda ukubaluleka kokuchaneka kwe-angular, engasoloko ifumaneka ngokulula, kukunceda ukuba uphephe iingxaki ezininzi ezinokuthi zibekho kwinqanaba lokuqala elibalulekileyo leprojekthi. Ii-servos ezingabizi kakhulu kodwa ezichanekileyo zinokubangela iimpazamo ezikhulayo kwinkqubo yonke, ekugqibeleni zichaphazela ukusebenza kwayo ngokubanzi kwaye zikhokelela kwimiphumo emibi.

Ke ngoko, xa ukhetha i-servo, kufuneka uphonononge ngokucophelela iiparitha ezinxulumene nokuchaneka kwinkcazo kwaye ubeke phambili iimveliso ezichaza ngokucacileyo imigangatho yazo yokuchaneka, kunokuba wenze izigqibo ezisekelwe kuphela kumava adlulileyo okanye ixabiso.

Kutheni ukuchaneka kwe-Angular kubalulekile kwiiProjekthi

Ukuchaneka kwe-angular kuqinisekisa ngokuthe ngqo ukuphunyezwa okuthembekileyo kwemisebenzi ngezixhobo. Umzekelo,ukuba usebenza kwinkqubo yokulandelela ngokuzenzekelayo, ukuchaneka kakubi kwe-servo kuya kuthintela ikhamera ekujoliseni ngokuchanekileyo ekujoliswe kuyo, ukunciphisa kakhulu ukulandelela ukusebenza.Ngokufanayo, kwimizi-mveliso ezenzekelayo, i-servo ephantsi inokubangela ukungasebenzi kakuhle kwengalo yerobhothi kunye neengxaki zemveliso.

Ukuchaneka okunganelanga akuchaphazeli kuphela ukusebenza kodwa kwandisa kakhulu ixesha lokumisela kunye neendleko ngenxa yesidingo sokulinganisa okuphindaphindiweyo okanye ukutshintshwa kwecandelo.

Ngokwembono yamava omsebenzisi, ii-servos ezichaneke kakhulu zenza kube lula kunye nokusebenza kwesixhobo sobuchwephesha. Umzekelo, kwiirobhothi zemfundo okanye iithoyi ezikrelekrele, iintshukumo ezichanekileyo zongeza unxibelelwano kwaye zithintele ukukhungatheka komsebenzisi okubangelwa zizixhobo ezingaphenduliyo.

Ngoko ke, ngelixa utyalo-mali kwii-servos ezichanekileyo zingabonakala zinyusa iindleko zokuqala, ngokwenene ziphucula amazinga okuphumelela kweprojekthi kunye nokuzinza kwexesha elide, okwenza kube lukhetho oluneendleko eziphezulu.

Ungazikhetha njani iiServo zoKuchaneka okuphezulu

Xa ukhetha i-servo ephezulu echanekileyo, inyathelo lokuqala kukukhangela iinkcukacha zemveliso kwaye ujonge amanani acacileyo amanani ukuchaneka kwe-angular, njenge-± 0.5 ° okanye ± 1 °. Ngokuqhelekileyo, ii-servos zedijithali zichaneke ngakumbi kune-analog servos kuba zisebenzisa i-microprocessors kulawulo lwe-loop evaliweyo, evumela ukulungiswa kwexesha lokwenyani.

Ngelo xesha, qaphela uhlobo lwe-servo; iimotor ezingena-brushless okanye ii-motor coreless zihlala zinezibonelelo malunga nokuchaneka kunye nexesha lokuphila, ngelixa ii-motor ezingenasiphelo zibonelela ngeenzuzo kwixesha elide eliqhubekayo lokusebenza kunye nokulahla ubushushu obungcono.

Cinga ngemeko yesicelo.Ukuba iprojekthi yakho ifuna impendulo ekhawulezayo kunye nokuchaneka okuphezulu, unokukhetha i-servo yedijithali exhasa izinga eliphezulu lokuhlaziya; ukuba uhlahlo lwabiwo-mali lwakho lulinganiselwe kodwa iimfuno zokuchaneka azikho phezulu, i-servo eqhelekileyo inokwanela.

Ukongezelela, funda uphononongo lwabasebenzisi kunye neengxelo zovavanyo ukuqonda ukusebenza ngokuchanekileyo ekusetyenzisweni kwangempela, ukuphepha izigqibo ezisekelwe kuphela kwiiparamitha zethiyori. Khumbula, ii-servos ezichaneke kakhulu ngokubanzi zifuna amandla ombane aphezulu kunye nenkxaso yolawulo olungcono lweprotocol, efana neebhasi ze-TTL okanye iibhasi ze-CAN.

Zeziphi Izinto Ezichaphazela Ukuchaneka kweServo?

Ukuchaneka kwe-servo motor kuchatshazelwa yizinto ezahlukeneyo, ezibandakanya zombini isakhiwo sangaphakathi kunye nokusingqongileyo kwangaphandle. Izinto zangaphakathi zibandakanya ukubuyisela umva wegiya, uhlobo lweemoto, kunye nenkqubo yempendulo. Ii-servos ezine-backlash enkulu ziya kuba ne-hysteresis ngexesha lokujikeleza okubuyela umva, okukhokelela ekunciphiseni ukuchaneka.

Nangona kunjalo, ii-servos ezivaliweyo ezineekhowudi zisebenzisa iindlela zokunika ingxelo ukunciphisa iimpazamo, ngaloo ndlela ziphucula ukuchaneka. Izinto zangaphandle ziquka ukuzinza kwamandla ombane, umgangatho wesignali yokulawula, kunye nokwahluka komthwalo.

Umzekelo, ukuguquguquka kwamandla ombane kunokubangela lula ukungalingani kwezantya zokujikeleza kwe-servo, okuchaphazela ukuchaneka kwendawo. Ingxolo kwisignali yolawulo inokuphazamisana nokutolika komyalelo we-servo. Ngaphaya koko, umthwalo ogqithisileyo okanye ukufakela okungafanelekanga nako kunokukhokelela ekulahlekeni kokuchaneka.

Ngoko ke,xa usebenzisa i-servos ephezulu echanekileyo, kubalulekile ukuqinisekisa ukunikezelwa kwamandla okuzinzile, umqondiso ococekileyo, kunye nesakhiwo esilungiselelwe kakuhle somatshini ukwenzela ukwandisa ukusebenza.

UVavanya njani kwaye ulungelelanise ukuchaneka kweServo?

Ungasebenzisa izixhobo ezilula, ezifana nei-angle gauge okanye i-laser pointer, ukuthumela imiqondiso echanekileyo kumlawuli ukuvavanya ukuchaneka kwe-servo.Jikelezisa i-servo kwii-engile ekujoliswe kuzo ezininzi, ezifana ne-0 °, 90 °, kunye ne-180 °, uze ulinganise indawo yokwenyani kwaye ubale ukutenxa.

Phinda le nkqubo amaxesha amaninzi kwaye uthathe i-avareji ukuvavanya ukuphindaphinda. Ukuba ukutenxa kukhulu, ulungelelwaniso lunokufuneka. Iinkonzo ezininzi zedijithali zixhasa ulungelelwaniso lwesoftware, ehlawula iimpazamo ngokulungelelanisa iiparamitha zolawulo.

Ulungelelwaniso lubandakanya ukuthumela imiyalelo yolungelelwaniso okanye ukusebenzisa isoftwe ekhethekileyo. Ngokomzekelo, i-microcontroller ingathumela isignali ye-PWM kwaye irekhode umahluko phakathi kweyona ndawo kunye nexabiso lethiyori, emva koko yongeza i-offset kwikhowudi ukuyilungisa.

Ukuvavanya rhoqo kunye nokulinganisa kunokwandisa ubomi be-servo kunye nokuqinisekisa ukusebenza okuzinzileyo kwexesha elide. Kwizicelo ezibalulekileyo, kuyacetyiswa ukuba ugcwalise la manyathelo phambi kofakelo ukuthintela iingxaki ngexesha lolungiso lweempazamo kamva.

Usetyenziso oluQhelekileyo lweeNkonzo zokuChaneka okuphezulu

Iinkonzo ezichanekileyo ezichanekileyo zisetyenziswa ngokubanzi kwiinkalo ezifuna ulawulo oluchanekileyo, njengeiirobhothi, i-aerospace, kunye nezixhobo zonyango. Kwirobhothi, isetyenziswa kwii actuators ezidibeneyo ukuqinisekisa iintshukumo ezigudileyo kunye nokubamba ngokuchanekileyo.

Kwi-drone gimbals, ii-servos ezichanekileyo ezichanekileyo zinceda ukuzinzisa iikhamera, okukhokelela kwimifanekiso ecacileyo. Ngaphaya koko, amakhethini azenzekelayo kunye neekhamera zokhuseleko kumakhaya alumkileyo axhomekeke ekuchanekeni kwe-servo ukuze asebenze kakuhle.

Kule meko, ukuchaneka kuhambelana ngokuthe ngqo nokhuseleko lwenkqubo kunye nokusebenza kakuhle. Umzekelo,kwiirobhothi zonyango, neempazamo zomzuzu zinokukhokelela ekohlulekeni kotyando, ngoko ke kubalulekile ukukhetha ukuchaneka okuphezulu, ukuthembeka okuphezulu kwe-servos.Ukuqonda ezi zicelo kunokukunceda ukuba ucwangcise ngcono iiprojekthi zakho kwaye ukhethe iintlobo ezifanelekileyo ze-servo ukuphucula ukusebenza ngokubanzi.
