Ubwino wa DD motor

Ma Servo motors nthawi zambiri amakhala osakhazikika chifukwa cha torque yosakwanira komanso kugwedezeka panthawi yogwira ntchito pa liwiro lotsika.Kutsika kwa magiya kudzachepetsa mphamvu, kumasula komanso phokoso lidzachitika magiya akamalumikizidwa, ndikuwonjezera kulemera kwa makina.Pakugwiritsa ntchito kwenikweni, mbali yozungulira ya index plate pakugwira ntchito nthawi zambiri imakhala mkati mwa bwalo, ndipo torque yayikulu yoyambira nthawi yomweyo imafunika.Galimoto ya DD, yopanda chochepetsera, imakhala ndi torque yayikulu ndipo imagwira ntchito moyenera komanso yokhazikika pama liwiro otsika.

Tmawonekedwe ake a DD motor

1, Mapangidwe a galimoto ya DD ali mu mawonekedwe a rotor yakunja, yomwe ndi yosiyana ndi AC servo ya mkati mwa rotor.Kuchuluka kwa mitengo ya maginito mkati mwa mota nakonso kumakhala kokulirapo, zomwe zimapangitsa kuti pakhale koyambira komanso kutembenuka kwakukulu.

2, Ma radial omwe amagwiritsidwa ntchito mugalimoto amatha kukhala ndi mphamvu yayikulu ya axial.

3, encoder ndi grating yozungulira yokhazikika kwambiri.Chigamulo chozungulira chomwe chimagwiritsidwa ntchito ndi jDS DD motor ndi 2,097,152ppr, ndipo chimakhala ndi chiyambi ndi malire.

4, Chifukwa cha mayankho olondola kwambiri komanso njira zopangira zapamwamba, kulondola kwa malo agalimoto ya DD kumatha kufika pamlingo wachiwiri.(Mwachitsanzo, kulondola kwenikweni kwa mndandanda wa DME5A ndi ± 25arc-sec, ndipo kulondola kobwerezabwereza ndi ± 1arc-sec)

DD motor ndi servo motor + reducer ali ndi zosiyana izi:

1: Kuthamanga kwambiri.

2: Torque yayikulu (mpaka 500Nm).

3: Kulondola kwambiri, kusasunthika kwa shaft, kuwongolera kwapamwamba kwambiri kumatha kutheka (kubwerezanso kwambiri ndi sekondi imodzi).

4: Kulondola kwamakina apamwamba, kuthamanga kwa mota axial ndi radial kumatha kufikira mkati mwa 10um.

5: Katundu wokwera, mota imatha kupirira mpaka 4000kg ya kupsinjika mumayendedwe axial ndi ma radial.

6: Kukhazikika kwakukulu, kulimba kwambiri kwa ma radial komanso kuthamanga kwamphamvu.

7: Galimoto ili ndi dzenje lolowera mosavuta zingwe ndi mapaipi a mpweya.

8: Kusamalira, moyo wautali.

Ndemanga

Ma motors a DDR nthawi zambiri amagwiritsa ntchito mayankho a optical incremental encoder.Komabe, palinso mitundu ina ya mayankho oti musankhe, monga: encoder ya solver, absolute encoder ndi inductive encoder.Ma encoder owoneka amatha kupereka kulondola kwabwinoko komanso kusamvana kwapamwamba kuposa ma encoder osinthira.Mosasamala kanthu za kukula kwa injini ya DDR yapamwamba kwambiri, phula la chowongolera cha optical encoder grating nthawi zambiri chimakhala ma microns 20.Kupyolera mu kumasulira, kusamvana kwakukulu kungapezeke kuti mukwaniritse zolondola zomwe zimafunidwa ndi ntchitoyo.Mwachitsanzo: DME3H-030, grating phula ndi 20 microns, pali mizere 12000 pa kusintha, muyezo interpolation magnification ndi nthawi 40, ndi kusamvana pa kusintha ndi mayunitsi 480000, kapena kusamvana ndi grating monga ndemanga ndi 0,5 microns.Pogwiritsa ntchito SINCOS (encoder ya analogi), pambuyo pa nthawi za 4096 zotanthauzira, chigamulo chomwe chingapezeke ndi mayunitsi 49152000 pakusintha, kapena chisankho chokhala ndi grating monga ndemanga ndi 5 nanometers.
