1, Ziziphi iintlobo zeemoto ezincinci ze-stepper? Zithini iimpawu zazo?
Yahlulwe yangamacandelo amathathu ngokusekelwe kwisakhiwo serotor. Uhlobo lwe-PM (uhlobo lwemagnethi oluhlala luhleli) lunesakhiwo esilula, ixabiso eliphantsi, kunye ne-engile yenyathelo edla ngokuba yi-7.5 ° okanye i-15 °. Ine-torque encinci kwaye ifanelekile kwizicelo ezifana neeprinta kunye nee-gimbals zekhamera ezingadingi ukuchaneka okuphezulu; ii-rotor zohlobo lwe-VR (ukungafuni ukutshintsha) zenziwe ngezinto ezithambileyo zemagnethi ezinesisombululo esiphantsi (malunga nesiqingatha sohlobo lwe-HB) kunye neempawu zexesha elifutshane, kwaye ngoku azisetyenziswa rhoqo; Uhlobo lwe-HB (i-hybrid) ludibanisa izibonelelo zezimbini zokuqala, kunye ne-engile yesinyathelo eqhelekileyo ye-1.8 ° okanye i-0.9 °, i-torque ephezulu, kunye nesisombululo esiphezulu, okwenza kube lukhetho oluphambili lwezixhobo ezincinci zokuchaneka.
2, Ithini indlela echanekileyo ngayo i-step angle yemoto encinci ye-stepper? Ngaba iimpazamo ziyaqokelelana?
Ukuchaneka kwemoto ye-stepper jikelele yi-3% ukuya kwi-5% ye-engile ye-step kwaye ayiqokeleli. Oku kuthetha ukuba nasemva kwemijikelo emininzi yokusebenza, iimpazamo zenyathelo ngalinye aziyi kuqokeleleka kwindawo yokugqibela. Ukuchaneka okuqhelekileyo kwemoto ye-hybrid micro stepper enezigaba ezimbini kunokufikelela kwi-0.18 ° (kwi-engile ye-step ye-1.8 °).
3, Ingakanani i-torque enokuthi ikhuphe i-miniature stepper motor?
Isithuba se-scope sikhulu kakhulu. I-torque yokubamba ubukhulu besiseko somatshini esingaphantsi kwe-20mm yohlobo lwe-PM inokuba yi-0.02N · m; I-NEMA 8~NEMA 11 (20mm~28mm) idla ngokuba phakathi kwe-0.03~0.1N · m; I-NEMA 14~NEMA 17 (35mm~42mm) ingafikelela kwi-0.2~0.5N · m. Ukudlula kwi-0.8N · m ngokubanzi kufuna isiseko se-NEMA 17 okanye ngaphezulu, esidlula udidi "oluncinci".
4, Kutheni i-torque ye-stepper motor iyancipha njengoko isantya sisanda?
Xa ijikeleza, i-winding inductance ivelisa i-reverse electromotive force, kwaye okukhona i-frequency iphezulu, kokukhona i-reverse electromotive force inkulu, nto leyo ebangela ukwehla kwe-phase current kunye ne-output torque. Ii-Micro motors zine-winding turns ezimbalwa kunye ne-inductance ephantsi, nto leyo eyenza esi siphumo sibonakale ngakumbi kwisantya esiphezulu.
5, Ngaba iimoto ezincinci ze-stepper zingasetyenziselwa intshukumo ethe tye?
Ewe. I-linear stepper motor idibanisa isikrufu kwi-rotor kwaye ikhuphe ngokuthe ngqo intshukumo ethe ngqo, isusa imfuneko yeendlela zokudlulisa zangaphandle. Ukubetha kwee-micro linear stepper motors kudla ngokuba phakathi kwe-10mm ~ 200mm, kunye ne-thrust ye-0.5N ~ 10N. Zisetyenziswa rhoqo kwiimpompo zokufaka, iimpompo zokufaka, kunye nezixhobo zotyando ezincinci.
6, Zeziphi iiparameter eziqalwa kuqala xa ukhetha i-micro stepper motor?
Okokuqala, misela i-torque yomthwalo kunye nendawo yokufaka. I-torque yokubamba kufuneka ibe ngaphezulu kwe-1.3 ye-torque yomthwalo yokwenyani. Ukuqwalasela ukuba ii-micro motors zinobuthathaka kakhulu ekugqithiseni kakhulu, kucetyiswa ukuba uthathe i-safety factor ye-1.4 ukuya kwi-2 amaxesha. Ukuqinisekisa indawo yokufaka ekhoyo, ubungakanani buhlala bungumqobo wokuqala kwizixhobo ezincinci.
7, Yintoni umahluko phakathi kokugcina i-torque kunye ne-dynamic torque?
Ukugcina i-torque yeyona torque iphezulu enokugcinwa yimoto ngombane olinganisiweyo xa imile, nto leyo ebonisa amandla ayo okuhlala ihleli. I-torque enamandla yi-torque yokwenyani yokukhupha ngexesha lokusebenza, exhomekeke kumbane oqhelekileyo ngexesha lokusebenza kwaye yehla ngesantya esonyukayo. Xa sikhetha, asinakugxila kuphela ekugcineni i-torque, kufuneka sibhekisele kwi-curve ye-torque frequency characteristic curve.
8, Ungayikhetha njani ubungakanani besiseko ngokusekelwe kwi-torque?
Isalathiso samava: I-NEMA 8~NEMA 17 ingakhethwa ngaphantsi kwe-0.8N · m; Ngaphantsi kwe-0.1N · m, i-NEMA 8~NEMA 11 idla ngokwanela. Kwiimeko ze-micro application, imfuno ye-torque idla ngokuba ngaphakathi kwe-0.5N · m, kunye ne-NEMA 14~NEMA 17 njengoluhlu oluphambili.
9, Ungawuqonda njani umlinganiselo wamandla ombane we-miniature stepper motor?
Umbane oqhubayo (umbane wesigaba) lixabiso elibhekiselele kumbane kuzo zombini iziphelo zomjikelo wesigaba esinye, kwaye awungomda opheleleyo. Ungalungiswa malunga nexabiso elilinganisiweyo ngokweemeko zokusebenza zangempela, kodwa ukudlula ixabiso elilinganisiweyo kuya kwandisa ukufudumeza, kwaye ngaphantsi kwexabiso elilinganisiweyo kuya kubangela i-torque enganeleyo. Ukumelana nokujija kwee-motor ezincinci kuphezulu, kwaye umbane oqhubayo oqhelekileyo ukwi-0.2 ~ 1.5A.
10, Ngaba ukufanisa i-inertia kubalulekile xa ukhetha ii-micro stepper motors?
Kubaluleke kakhulu. Umlinganiselo we-load inertia kwi-motor rotor inertia uphezulu kakhulu, nto leyo enokubangela impendulo engalunganga ye-dynamic kunye nokulahleka kwenyathelo ngokulula ngexesha lokukhawulezisa. I-inertia ye-rotor ye-micro motor ngokwayo incinci kakhulu, kodwa i-inertia kwicala lomthwalo (njenge-screw kunye ne-coupling) inokuba nkulu kakhulu kuneye-motor ngokwayo, ngoko ke kufuneka ibalwe xa ukhetha.
