I-Closed-loopiimoto ze-stepperbatshintshe umlinganiselo wokusebenza-neendleko kwizicelo ezininzi zolawulo lokuhamba. Impumelelo yeemoto eziqhubekekayo ze-VIC ezivaliweyo ikwavule ithuba lokutshintsha iimoto ze-servo ezibizayo ngezithuthi ezingabizi kakhulu.iimoto ze-stepperKwinani elikhulayo lezicelo ze-automation zoshishino ezisemgangathweni ophezulu, inkqubela phambili kwezobuchwepheshe itshintsha umlinganiselo wokusebenza-neendleko phakathi kwee-stepper motors kunye nee-servo motors.
Iimoto zeStepper xa kuthelekiswa neemoto zeservo
Ngokwengqiqo eqhelekileyo, iinkqubo zolawulo lwe-servo zisebenza ngcono kwiindawo apho kufuneka isantya esingaphezulu kwe-800 RPM kunye nempendulo ephezulu enamandla. Iimoto ze-Stepper zilungele ngakumbi kwiindawo apho isantya siphantsi, isantya esiphantsi ukuya kwesiphakathi kunye ne-torque ephezulu yokubamba.
Ngoko ke yintoni isiseko sobulumko obuqhelekileyo malunga nee-stepper motors kunye nee-servo motors? Masiyihlalutye ngokweenkcukacha ezithe vetshe apha ngezantsi.
1. Ubulula kunye neendleko
Iimoto zeStepper azibizi nje kuphela kuneemoto zeservo, kodwa kulula nokuzisebenzisa nokuzilungisa. Iimoto zeStepper zizinzile xa zimile kwaye zigcina indawo yazo (nokuba zinemithwalo enamandla). Nangona kunjalo, ukuba kufuneka ukusebenza okuphezulu kwizicelo ezithile, kufuneka kusetyenziswe iimoto zeservo ezibizayo nezintsonkothileyo.
2. Ulwakhiwo
Iimoto ze-stepperjikeleza ngendlela ethe tye, usebenzisa iikhoyili zemagnethi ukutsala kancinci imagnethi ukusuka kwenye indawo ukuya kwenye. Ukuze imoto ihambe izikhundla ezili-100 kuyo nayiphi na indlela, isekethe ifuna imisebenzi yokunyathela eli-100 kwimoto. Iimoto zeStepper zisebenzisa iipulses ukufezekisa iintshukumo ezinyukayo, zivumela indawo echanekileyo ngaphandle kokusebenzisa naziphi na izinzwa zempendulo.
Indlela yokuhamba kwemoto yeservo yahlukile. Idibanisa isenzi sendawo - oko kukuthi i-encoder - kwi-magnetic rotor kwaye ihlala ibona indawo eyiyo ngqo yemoto. I-servo ijonga umahluko phakathi kwendawo eyiyo kanye nendawo eyiyalelweyo kwaye ilungisa umbane ngokufanelekileyo. Le nkqubo ye-closed-loop igcina imoto ikwimeko eyiyo yokuhamba.
3. Isantya kunye ne-torque
Umahluko ekusebenzeni phakathi kweemoto ze-stepper kunye neemoto ze-servo uvela kwizisombululo zazo ezahlukeneyo zoyilo lweemoto.Iimoto ze-stepperzinenani elikhulu kakhulu leepali kunee-servomotors, ngoko ke ukujikeleza okupheleleyo kwe-stepper motor kufuna utshintsho oluninzi lwamandla olujikelezayo, nto leyo ebangela ukwehla ngokukhawuleza kwe-torque xa isantya sinyuka. Ukongeza, ukuba i-torque ephezulu ifikelelwe, i-stepper motor inokulahlekelwa ngumsebenzi wayo wokuvumelanisa isantya. Ngenxa yezi zizathu, ii-servo motors zezona sisombululo zikhethwayo kwizicelo ezininzi zesantya esiphezulu. Ngokwahlukileyo koko, inani eliphezulu leepali ze-stepper motor liluncedo xa isantya siphantsi, xa i-stepper motor inenzuzo ye-torque kune-servo motor enobukhulu obufanayo.
Njengoko isantya sisanda, i-torque ye-stepper motor iyancipha
4. Ukubeka indawo
Kukho umahluko obalulekileyo phakathi kwee-stepper motors kunye nee-servo motors kwizicelo apho indawo echanekileyo yomatshini kufuneka yaziwe ngamaxesha onke. Kwizicelo zentshukumo evulekileyo elawulwa zii-stepper motors, inkqubo yolawulo icinga ukuba imoto isoloko ikwimeko echanekileyo yokuhamba. Nangona kunjalo, emva kokuba kufumaneke ingxaki, njengemoto emileyo ngenxa yecandelo elibambekileyo, umlawuli akakwazi ukwazi indawo yokwenyani yomatshini, nto leyo enokukhokelela ekulahlekelweni kwendawo. Inkqubo ye-closed-loop yemoto ye-servo ngokwayo inenzuzo: ukuba ixinyiwe yinto, iya kuyifumanisa ngoko nangoko. Umatshini uya kuyeka ukusebenza kwaye awusoze uphume kwindawo yawo.
5. Ukusetyenziswa kobushushu namandla
Iimoto ze-open-loop stepper zisebenzisa umbane ozinzileyo kwaye zikhupha ubushushu obuninzi. Ulawulo oluvaliweyo lubonelela kuphela ngombane ofunekayo kwisantya somjikelo kwaye ngaloo ndlela luthintela ingxaki yokufudumeza kwemoto.
Isishwankathelo sothelekiso
Iinkqubo zolawulo lwe-Servo zilungele kakhulu usetyenziso olukhawulezayo olubandakanya utshintsho lomthwalo oluguquguqukayo, njengeengalo zerobhothi. Iinkqubo zolawulo lwe-Stepper, kwelinye icala, zilungele ngakumbi usetyenziso olufuna ukukhawuleziswa okuphantsi ukuya kokuphakathi kunye ne-torque ephezulu yokubamba, njengeeprinta ze-3D, ii-conveyors, ii-sub axes njl. Ngenxa yokuba ii-stepper motors zingabizi kakhulu, zinokunciphisa iindleko zeenkqubo zokwenza izinto ngokuzenzekelayo xa zisetyenziswa. Iinkqubo zolawulo lokuhamba ezifuna ukusebenzisa iimpawu zee-servo motors kuya kufuneka zibonakalise ukuba ezi moto zibiza kakhulu zixabisa ubunzima bazo ngegolide.
Iimoto zeStepper ezinolawulo oluvaliweyo
I-stepper motor enolawulo oludibeneyo lwe-elektroniki ilingana ne-DC motor engenamaqhosha amabini kwaye inokwenza ulawulo lwe-position loop, ulawulo lwe-speed loop, ulawulo lwe-DQ, kunye nezinye ii-algorithms. I-single-turn absolute encoder isetyenziselwa i-closed-loop commutation, ngaloo ndlela iqinisekisa i-torque efanelekileyo kuyo nayiphi na isantya.
Ukusetyenziswa kwamandla aphantsi kunye nokugcina upholile
Iimoto ze-VIC stepper zisebenza kakuhle kakhulu. Ngokungafaniyo neemoto ze-open-loop stepper, ezihlala zisebenza ngomyalelo opheleleyo wamandla kwaye zibangela iingxaki zobushushu nengxolo, umbane uyatshintsha ngokweemeko zokwenyani zokuhamba, umzekelo ngexesha lokukhawulezisa kunye nokuthomalalisa isantya. Njengee-servo, umbane osetyenziswa zezi moto ze-stepper nangaliphi na ixesha ulingana nombane ofunekayo. Ngenxa yokuba imoto kunye nebhodi yokulawula ye-elektroniki edibeneyo isebenza ngokupholileyo, iimoto ze-VIC stepper zinokufikelela kwiimoto eziphezulu kakhulu ezifana neemoto ze-servo.
Nokuba ngesantya esiphezulu, iimoto ze-VIC stepper azidingi mbane ungako
Ziqhutywa yinkqubela phambili kubuchwepheshe obuvaliweyo, iimoto ze-stepper ziyakwazi ukungena kwizicelo zokusebenza okuphezulu, ezinesantya esiphezulu ezazikade zizezeemoto ze-servo kuphela.
Iimoto zeStepper ezineteknoloji ye-closed-loop
Kuthekani ukuba iingenelo zobuchwepheshe be-servo obuvaliweyo zingasetyenziswa kwiimoto ze-stepper?
Ngaba singafikelela ekusebenzeni okufanayo nee-servo motors ngelixa sisaqonda iingenelo zeendleko zee-stepper motors?
Ngokudibanisa itekhnoloji yokulawula i-closed-loop, i-stepper motor iya kuba yimveliso epheleleyo enezibonelelo zee-servo kunye nee-stepper motors ngexabiso eliphantsi. Ngenxa yokuba ii-closed-loop stepper motors zibonelela ngophuculo olukhulu ekusebenzeni nasekusebenziseni kakuhle amandla, zinokuthatha indawo yee-servo motors ezibizayo kwinani elikhulayo lezicelo ezisemgangathweni ophezulu.
Oku kulandelayo ngumzekelo wemoto ye-stepper edityanisiweyo ye-VIC enolawulo lwe-closed-loop olufakwe ngaphakathi ukuchaza ukusebenza kunye neenzuzo kunye nokungalungi kweemoto ze-stepper ezineteknoloji ye-closed-loop.
Iimfuno zokusebenza ezihambelana ngokuchanekileyo
Ukuze kuqinisekiswe ukuba i-torque yanele ukoyisa ukuphazamiseka nokuphepha amanyathelo alahlekileyo, ii-open-loop stepper motors zihlala zifuna ukuqinisekisa ukuba i-torque iphezulu ngama-40% ubuncinane kunexabiso elifunekayo kwisicelo. Ii-closed-loop today stepper motors azinalo le ngxaki. Xa ezi stepper motors zima ngenxa yokugqithiswa kakhulu, ziya kuqhubeka nokubamba umthwalo ngaphandle kokulahlekelwa yi-torque. Ziya kuqhubeka nokusebenza emva kokuba imeko yokugqithiswa kakhulu isusiwe. I-torque ephezulu inokuqinisekiswa nangaliphi na isantya esinikiweyo kwaye i-sensor yendawo iqinisekisa ukuba akukho lahleko yesinyathelo. Ii-closed-loop stepper motors ke ngoko zinokuchazwa ukuba zihambelane ngqo neemfuno ze-torque zesicelo esifanelekileyo ngaphandle kwesidingo somda owongezelelweyo wama-40%.
Ngeemoto ze-open-loop stepper, kunzima ukuhlangabezana neemfuno eziphezulu ze-torque ngenxa yomngcipheko wokulahleka kwamanyathelo. Xa kuthelekiswa neemoto ze-stepper eziqhelekileyo, iimoto ze-VIC closed-loop stepper zinokufikelela ekukhawuleziseni ngokukhawuleza, ingxolo ephantsi yokusebenza kunye ne-resonance ephantsi. Zingasebenza kwiibhendi eziphezulu kakhulu kwaye zifezekise ukusebenza okugqwesileyo.
Akukho khabhinethi
I-Toda idibanisa ibhodi yokulawula idrayivu nemoto, inciphisa ubungakanani beentambo kwaye yenza kube lula ukuphumeza isisombululo. Nge-toda, ungakha oomatshini ngaphandle kweekhabhathi.
Ukudibanisa izixhobo ze-elektroniki kunye neemoto ze-stepper kunciphisa ubunzima
Ngeteknoloji ye-closed-loop, ii-closed-loop stepper motors zinika abasebenzisi ukuchaneka nokusebenza kakuhle, kunye nokusebenza kakuhle kwe-servo motor kunye nexabiso eliphantsi le-stepper motor. Ii-stepper motors ezixabisa kancinci zingena kancinci kancinci kwizicelo ebezinokulawulwa zii-servo motors ezixabisa kakhulu.
