1, Yiziphi izinhlobo zama-miniature stepper motors? Yiziphi izici zawo?
Ihlukaniswe ngezigaba ezintathu ngokusekelwe kwisakhiwo se-rotor. Uhlobo lwe-PM (uhlobo lwe-permanent magnet) lunesakhiwo esilula, izindleko eziphansi kakhulu, kanye ne-engeli yesinyathelo ngokuvamile engu-7.5 ° noma 15 °. Lune-torque encane futhi lufanelekela izinhlelo zokusebenza ezifana namaphrinta nama-gimbal ekhamera angadingi ukunemba okuphezulu; ama-rotor ohlobo lwe-VR (ukwenqaba okuguquguqukayo) enziwe ngezinto ezithambile ze-magnetic ezine-resolution ephansi (cishe ingxenye yohlobo lwe-HB) kanye nezici zesikhashana ezimbi, futhi manje azisasetshenziswa kakhulu; Uhlobo lwe-HB (i-hybrid) luhlanganisa izinzuzo zezimbili zokuqala, ne-engeli yesinyathelo evamile engu-1.8 ° noma 0.9 °, i-torque ephezulu, kanye ne-resolution ephezulu, okwenza kube ukukhetha okujwayelekile kwemishini yokunemba okuncane.
2, Kuyini ukunemba kwe-engeli yesinyathelo semoto encane ye-stepper? Ingabe amaphutha azoqongelela?
Ukunemba kwemoto ye-stepper ejwayelekile kungu-3% kuya ku-5% we-engeli yesinyathelo futhi akuqongelelani. Lokhu kusho ukuthi ngisho nangemva kwemijikelezo eminingi yokusebenza, amaphutha esinyathelo ngasinye ngeke aqongelelani endaweni yokugcina. Ukunemba okuvamile kwemoto ye-hybrid micro stepper enezigaba ezimbili kungafinyelela ku-0.18 ° (nge-engeli yesinyathelo engu-1.8 °).
3, Ingakanani i-torque engakhishwa yi-miniature stepper motor?
Isikhala se-scope sikhulu kakhulu. I-torque yokubamba yosayizi besisekelo somshini ongaphansi kwama-20mm ohlobo lwe-PM ingaba ngu-0.02N · m kuphela; I-NEMA 8~NEMA 11 (20mm~28mm) ngokuvamile isukela ku-0.03~0.1N · m; I-NEMA 14~NEMA 17 (35mm~42mm) ingafinyelela ku-0.2~0.5N · m. Ukudlula ku-0.8N · m ngokuvamile kudinga isisekelo se-NEMA 17 noma ngaphezulu, esidlula isigaba "esincane".
4, Kungani i-torque yemoto ye-stepper incipha njengoba ijubane likhuphuka?
Uma ijikeleza, i-winding inductance ikhiqiza amandla e-reverse electromotive, futhi uma imvamisa iphakeme, amandla e-reverse electromotive amakhulu, okuholela ekunciphiseni kwamandla kagesi kanye ne-torque yokukhipha. Ama-micro motors anokujika okumbalwa kanye ne-inductance ephansi, okwenza lo mphumela ubonakale kakhulu ngesivinini esiphezulu.
5, Ingabe ama-motor amancane e-stepper angasetshenziswa ukunyakaza okuqondile?
Yebo. I-linear stepper motor ihlanganisa isikulufu ku-rotor futhi ikhiphe ngqo ukunyakaza okuqondile, isusa isidingo sezindlela zokudlulisa zangaphandle. Ukushaya kwama-micro linear stepper motors ngokuvamile kuphakathi kuka-10mm ~ 200mm, ngokucindezela okungu-0.5N ~ 10N. Avame ukusetshenziswa kumaphampu okufaka, amaphampu okufaka, kanye nezinsimbi zokuhlinzwa ezincane.
6, Yimaphi amapharamitha aqalwa kuqala lapho kukhethwa imoto encane ye-stepper?
Okokuqala, nquma i-torque yomthwalo kanye nendawo yokufaka. I-torque yokubamba kufanele ibe ngaphezu kwe-torque yomthwalo yangempela ngokuphindwe ka-1.3. Uma ubheka ukuthi ama-micro motors azwela kakhulu ekuthwaleni ngokweqile, kunconywa ukuthatha isici sokuphepha sezikhathi ezingu-1.4 kuya kwezi-2. Ngesikhathi esifanayo kuqinisekiswa isikhala sokufaka esitholakalayo, usayizi uvame ukuba yisithiyo sokuqala kumadivayisi amancane.
7, Uyini umehluko phakathi kokugcina i-torque kanye ne-torque enamandla?
Ukugcina i-torque kuyi-torque ephezulu kakhulu injini engayigcina ngogesi olinganiselwe uma ingashintshi, okubonisa ikhono layo elingaguquki. I-torque enamandla iyi-torque yangempela yokukhipha ngesikhathi sokusebenza, encike kugesi ojwayelekile ngesikhathi sokusebenza futhi yehla ngesivinini esandayo. Lapho sikhetha, asikwazi ukugxila kuphela ekugcineni i-torque, kumelwe sibhekisele kujika elichaza imvamisa ye-torque.
8, Ungakhetha kanjani usayizi wesisekelo ngokusekelwe ku-torque?
Ireferensi yesipiliyoni: I-NEMA 8~NEMA 17 ingakhethwa ngaphansi kuka-0.8N · m; Ngaphansi kuka-0.1N · m, i-NEMA 8~NEMA 11 ivame ukwanele. Ezimweni zokusetshenziswa okuncane, isidingo se-torque ngokuvamile singaphakathi kuka-0.5N · m, kanti i-NEMA 14~NEMA 17 iyibanga eliyinhloko.
9, Ungawuqonda kanjani ugesi olinganisiwe wenjini encane ye-stepper?
Ugesi wokushayela (ugesi wesigaba) uyinani elibhekisela kugesi kuzo zombili iziphetho zokugoqa kwesigaba esisodwa, futhi akuyona umkhawulo ophelele. Ungalungiswa ngenani elilinganiselwe ngokwezimo zokusebenza zangempela, kodwa ukudlula inani elilinganiselwe kuzokhulisa ukushisa, futhi ngaphansi kwenani elilinganiselwe kuzoholela ekubangeni okunganele kwe-torque. Ukumelana nokugoqa kwama-micro motors kuphakeme kakhulu, futhi ugesi wokushayela ojwayelekile usebangeni lika-0.2 ~ 1.5A.
10, Ingabe ukufanisa i-inertia kubalulekile lapho ukhetha ama-motor amancane e-stepper?
Kubaluleke kakhulu. Isilinganiso se-load inertia ne-motor rotor inertia siphezulu kakhulu, okungaholela ekuphenduleni okungekuhle kwe-dynamic kanye nokulahlekelwa yisinyathelo okulula ngesikhathi sokusheshisa. I-inertia ye-rotor ye-micro motor ngokwayo incane kakhulu, kodwa i-inertia ohlangothini lomthwalo (njengesikulufu kanye nokuxhuma) ingaba nkulu kakhulu kuneye-motor uqobo, ngakho-ke kumele ibalwe lapho kukhethwa.
