Ngingayikhetha kanjani injini ye-torque ephezulu?

Ukuqonda Ukuthi “I-Torque Ephakeme” Isho Ukuthini Ngempela

I-torque eqinile yokubamba ngokumelene netorque eguqukayo

Lapho abantu bekhuluma ngenjini “ye-torque ephezulu” enyathelayo, bavame ukubhekisela enanini letorque yokubamba kudathabhethi. Ukubamba i-torque iyitorque enkulu injini engamelana nayo lapho imile ngaphandle kokulahlekelwa izinyathelo, ngokuvamile ivezwa ngo-N·m (amamitha ama-newton) noma i-oz·in. Amamotho ajwayelekile e-NEMA 23 ahlinzeka ngetorque engu-1.0–3.0 N·m yokubamba, kuyilapho amamodeli we-torque engu-NEMA 34 aphezulu angase eqe u-8–12 N·m. Nokho, izinhlelo zokusebenza zangempela azivamile ukusebenza zimile. Lapho injini iqala ukujikeleza, i-torque etholakalayo iqala ukuncipha; lena i-torque eguquguqukayo, okufanele ihlolwe ngesivinini esidingekayo sokusebenza.

Enjinini ethile, ungase ubone u-3 N·m obambe itorque ngo-0 rpm kodwa u-2 N·m kuphela ngo-300 rpm no-1 N·m ngo-800 rpm. Ukukhetha imodeli "ye-torque ephezulu" kuphela ngokubamba i-torque kungaholela ezixazululweni ezingaphansi noma ezinkulu. Hlala uqhathanisa i-torque ngesivinini sakho sangempela sokusebenza ukusuka kwijika le-speed-torque.

Donsela - faka i-torque, khipha itorque, kanye ne-stall margin

I-torque enamandla ingahlukaniswa ibe yi-torque-in kanye ne-torque yokukhipha. I-torque ye-Pull-in iyi-torque ephezulu lapho injini ingaqala khona, ime, noma ihlehle ngokuvumelanisa ngaphandle kokulahlekelwa izinyathelo. I-torque ye-Pull-out iyi-torque ephezulu yokulayisha engashayelwa ngesivinini esithile, kucatshangwa ukuthi injini isivele isebenza ngalelo jubane. Ukuze usebenze okuthembekile, i-torque yokulayisha kufanele ihlale ngaphansi kokudonsa-kwi-torque ngesikhathi sokusheshisa nangaphansi kokudonsa-i-torque phakathi nesivinini esingaguquki.

Isibonelo, uma injini ine-torque yokudonsa engu-1.2 N·m ku-600 rpm kodwa i-torque edingekayo ingu-1.0 N·m, umkhawulo wesitebele kuphela (1.2 − 1.0) / 1.2 ≈ 17%. Umsebenzi wezimboni ngokuvamile uncoma okungenani u-30–50% wemajini ukuze kulawulwe izinguquko zokungqubuzana, ukukhuphuka kwezinga lokushisa, nokuguga. Uma uqhathanisa amasampula avela kumnikezeli wesitolo esikhulu noma efekthri, gcizelela ukuthi donsa-in/donsa-khipha amajika etorque, hhayi nje ukucaciswa kwetorque eyodwa.

Ukucacisa Izidingo Zohlelo Ngaphambi Kokukhetha Izimoto

Ichaza isivinini, umthwalo, kanye nomjikelezo wemisebenzi

Ngaphambi kokuxhumana nomkhiqizi noma amakhathalogi wokuphequlula, chaza amapharamitha amathathu abalulekile: isivinini esidingekayo, i-torque edingekayo kuleso sivinini, kanye nomjikelezo womsebenzi. Isivinini sivezwa nge-rpm noma izinyathelo ngomzuzwana. Isibonelo, isigaba sesikulufu esiholayo esidinga u-200 mm/s ngesikulufu esingu-8 mm sidinga u-1500 rpm (ngoba 200 mm/s / 8 mm/rev = 25 rev/s ≈ 1500 rpm). Uma umthwalo olayini ungu-200 N kanye nokusebenza kahle kwemishini kungu-0.8, imfuneko yetorque ithi:

• Torque = (Force × lead) / (2π × Ukusebenza kahle) = (200 N × 0.008 m) / (6.283 × 0.8) ≈ 0.51 N·m

Uma umshini usebenza ngokuqhubekayo amahora angu-16 ngosuku kule torque nesivinini, umjikelezo womsebenzi uphakeme futhi ukucatshangelwa kokushisa kuba bucayi kakhulu.

Ukubeka ukunemba, ukulungiswa, kanye ne-engeli yesinyathelo

Ama-Stepper motors awakhethelwa nje kuphela i-torque kodwa nendawo eqondile. Amamotho ajwayelekile ayi-hybrid stepper ane-engeli yesinyathelo engu-1.8° (izinyathelo ezingu-200 inguquko ngayinye). Ngezinyathelo ezincane eziyi-10 ngesinyathelo ngasinye esigcwele, uthola ama-microsteps angu-2000 inguquko ngayinye, noma u-0.18° nge-microstep ngayinye. Ngesikulufu esingu-5 mm sokuphakama, lokho kuhumushela ku-5 mm / 2000 ≈ 2.5 µm nge-microstep ngayinye.

Uma isistimu yakho idinga ukunemba kokuma okungu-±10 µm, akumele ucabangele nje ukulungiswa kwe-microstep kodwa futhi nokuhlehla komshini, ukungaqondani komshayeli, kanye ne-torque ripple. Ama-windings e-torque aphezulu avame ukuba ne-inductance ephakeme, engakhuphula kancane i-nonlinearity yesinyathelo ngesivinini esikhulu; lokhu kushintshaniswa kufanele kuhlolwe kusenesikhathi esakhiweni.

Ngokusekelwe kusivinini sakho oqondiswe kuso, ithoshi yomthwalo, umjikelezo wemisebenzi, nezimo ze-ambient, onjiniyela bakwa-Maxtech babala izilinganiso ze-inertia, batusa osayizi abafanelekile bozimele be-NEMA, futhi bachaze amaleveli afanelekayo amanje nawe-voltage. Ifektri ingakwazi ukwenza ngendlela oyifisayo ama-winding ukuze ithuthukise i-torque ephezulu-yesivinini, ithuthukise inertia ye-rotor, futhi ihlanganise abashayeli abahambisanayo nezinto zikagesi. Kungakhathaliseki ukuthi udinga ubuningi besampula noma ukuthunyelwa okuthe xaxa, i-Maxtech inikeza idatha ye-speed-torque eqinisekisiwe, imibiko yokuhlola okushisayo, nokusekelwa kohlelo lokusebenza, iqinisekisa ukuthi isitebhisi ngasinye esikhethiwe iletha i-torque ezinzile, ephezulu enokukhuphuka kwezinga lokushisa okulawulwayo nempilo ende yesevisi.
