1.Yintonii-motor ye-stepper?
Iinjini zeStepper zihamba ngokwahlukileyo kunezinye iinjini. DC stepper motors zisebenzisa discontinuous intshukumo. Kukho amaqela amaninzi ekhoyili emizimbeni yawo, abizwa “ngezigaba”, anokuthi ajikelezwe ngokuvula isigaba ngasinye ngokulandelelana. Inyathelo elinye ngexesha.
Ngokulawula i-stepper motor ngokusebenzisa isilawuli / ikhompyuter, unokumisa ngokuchanekileyo ngesantya esichanekileyo. Ngenxa yolu ncedo, ii-motor stepper zihlala zisetyenziswa ngokubanzi kwizixhobo ezifuna intshukumo echanekileyo.
Iinjini zeStepper zineesayizi ezininzi ezahlukeneyo, iimilo kunye noyilo. Eli nqaku liza kuchaza ngokuthe ngqo indlela yokukhetha i-stepper motor ngokweemfuno zakho.
2. Ziziphi iingenelo zeiinjini zokunyathela?
A. Ukuma-Ngenxa yokuba ukuhamba kweenjini ze-stepper kuchanekile kwaye kuphinda-phinda, zinokusetyenziswa kwiimveliso ezahlukeneyo ezilawulwa ngokuchanekileyo, ezifana noshicilelo lwe-3D, i-CNC, iqonga lekhamera, njl.
B. Ulawulo lwesantya-Amanyathelo achanekileyo athetha ukuba ungalawula ngokuchanekileyo isantya sokujikeleza, esilungele ukwenza iintshukumo ezichanekileyo okanye ulawulo lwerobhothi.
C. Isantya esiphantsi kunye netorque ephezuluNgokubanzi, iinjini zeDC zinetorque ephantsi ngezantya eziphantsi. Kodwa iinjini ze-stepper zine-torque ephezulu kwizantya ezisezantsi, ke zilukhetho olulungileyo lwezicelo ezichanekileyo ezinesantya esiphezulu.
3. Izinto ezingeloncedoi-motor ye-stepper :
A. Ukungasebenzi kakuhle- Ngokungafaniyo neemoto ze-DC, ukusetyenziswa kweenjini ze-stepper akuhambelani kakhulu nomthwalo. Xa bengawenzi umsebenzi, kusekho okwangoku, ngoko bahlala beneengxaki zokufudumeza, kwaye ukusebenza kakuhle kuphantsi kakhulu.
B. Torque ngesantya esiphezulu- Ngokuqhelekileyo i-torque ye-stepper motor kwisantya esiphezulu iphantsi kunesantya esiphantsi, ezinye iinjini zisenakho ukuphumeza ukusebenza okungcono kwisantya esiphezulu, kodwa oku kufuna i-drive engcono ukufezekisa esi siphumo.
C. Ayikwazi ukubeka iliso-Iinjini ze-stepper eziqhelekileyo azikwazi ukunika ingxelo / ukubona indawo yangoku yemoto, siyibiza ngokuthi "i-loop evulekileyo", ukuba ufuna "i-loop evaliweyo", kufuneka ufake i-encoder kunye nomqhubi, ukuze ukwazi ukubeka iliso / ukulawula ukujikeleza okuchanekileyo kwemoto nangaliphi na ixesha, kodwa ixabiso liphezulu kakhulu kwaye ayifanelekanga kwiimveliso eziqhelekileyo.
Inqanaba leMotor
4. Ukuhlelwa kokunyathela:
Kukho iintlobo ezininzi zeenjini ze-stepper, ezifanelekileyo kwiimeko ezahlukeneyo.
Nangona kunjalo, phantsi kweemeko eziqhelekileyo, ii-PM motors kunye nee-hybrid stepper motors zihlala zisetyenziswa ngaphandle kokuthathela ingqalelo iimotor zabucala.
5. Ubungakanani bemoto:
Ingqwalasela yokuqala xa ukhetha i-motor ubukhulu benjini. Iimotor zeStepper zisusela kwi-4mm miniature motors (esetyenziselwa ukulawula ukuhamba kweekhamera kwii-smartphones) ukuya kwii-behemoth ezinjenge-NEMA 57.
I-motor ine-torque esebenzayo, le torque imisela ukuba inokuhlangabezana nemfuno yakho yamandla emoto.
Umzekelo: I-NEMA17 isetyenziswa ngokubanzi kwiiprinta ze-3D kunye nezixhobo ezincinci ze-CNC, kunye neenjini ezinkulu ze-NEMA zisetyenziselwa ukuveliswa kwemveliso.
I-NEMA17 apha ibhekisa kwidayamitha yangaphandle ye-motor yi-intshi ezili-17, ubukhulu benkqubo ye-intshi, eyi-43cm xa iguqulelwa kwiisentimitha.
ETshayina, sisebenzisa iisentimitha kunye neemilimitha ukulinganisa imilinganiselo, hayi i-intshizi.
6. Inani lamanyathelo emoto:
Inani lamanyathelo ngenguqu yemoto nganye limisela isisombululo kunye nokuchaneka kwayo. Iinjini zeStepper zinamanyathelo ukusuka kwi-4 ukuya kuma-400 ngenguqu nganye. Ngokuqhelekileyo kusetyenziswa amanyathelo angama-24, 48 kunye nama-200.
Ukuchaneka kudla ngokuchazwa njengenqanaba lenyathelo ngalinye. Ngokomzekelo, inyathelo le-48-motor yi-7.5 degrees.
Nangona kunjalo, ukusilela kokuchaneka okuphezulu kukukhawuleza kunye ne-torque. Ngexesha elifanayo, isantya seenjini ezichanekileyo zisezantsi.
7. Ibhokisi yegiya:
Enye indlela yokuphucula ukuchaneka kunye netorque kukusebenzisa ibhokisi yegiya.
Umzekelo, i-gearbox ye-32: 1 inokuguqula i-motor enamanyathelo asi-8 ukuya kwi-motor echanekileyo engama-256, ngelixa inyusa i-torque ngama-8.
Kodwa isantya semveliso siya kuncitshiswa ngokuhambelanayo siye kwisinye sesibhozo sesokuqala.
Injini encinci inokufezekisa isiphumo setorque ephezulu ngebhokisi yegiya yokunciphisa.
8. Shaft:
Into yokugqibela ekufuneka uyiqwalasele yindlela yokutshatisa shaft yemoto kunye nendlela yokutshatisa inkqubo yakho yokuqhuba.
Iindidi zeeshafti zezi:
I-shaft ejikeleziweyo / i-D shaft: Olu hlobo lwe-shaft luyi-shaft ephumayo esemgangathweni, esetyenziselwa ukudibanisa i-pulleys, iiseti zegiya, njl.
I-shaft yegiya: I-shaft ye-output yezinye iimotor yigiya, esetyenziselwa ukutshatisa inkqubo ethile yegiya
I-Screw shaft: I-motor ene-screw shaft isetyenziselwa ukwakha i-actuator yomgca, kwaye isilayidi singongezwa ukufikelela kulawulo lomda.
Nceda uzive ukhululekile ukuba uqhagamshelane nathi ukuba unomdla kuyo nayiphi na i-motor yethu yokunyathela.
