Chithunzi 1: Servo motor ndi gawo lalikulu la servo system.
Ndi chitukuko cha ukadaulo wazidziwitso, kulumikizana ndi makina opangira makina, zida zosiyanasiyana zowongolera zokha zakhala zikugwiritsidwa ntchito popanga mafakitale komanso moyo watsiku ndi tsiku wamasiku ano. Monga chimodzi mwazida zodziwika bwino zowongolera zokha, makina a servo, opangidwa ndi servo motor ndi servo drive akhala akugwiritsidwa ntchito kwambiri pamoyo wathu watsiku ndi tsiku.
Ndi nkhani yathu apa, mutha kumvetsetsa mozama komwe servo motor ndi servo drive ingagwiritsidwe ntchito.
1. Kodi Servo System ndi chiyani?
Servo system, ndi njira yowongolera mayankho yomwe imagwiritsidwa ntchito kutsatira kapena kupanganso njira.
Monga chimodzi mwa zigawo zikuluzikulu za servo dongosolo ndi kuphedwa mbali yake, servo galimoto amasintha malo chinthu, kalozera, dziko ndi zina zotuluka ankalamulira kuchuluka kutsatira kulowetsa (kapena mtengo anapatsidwa).
Ntchito yake ndikukulitsa, kusintha ndikuwongolera mphamvu molingana ndi zofunikira za lamulo lowongolera, kotero kuti torque yotulutsa, liwiro ndi kuwongolera malo a chipangizo choyendetsa ndi chosinthika komanso chosavuta.
2. Zigawo za Servo System
Makinawa amapangidwa makamaka ndi HMI touch screen, PLC, servo drive, maginito okhazikika a synchronous servo motor. Servo motor ndiye njira yoyendetsera kayendetsedwe kake. Imayika, kuthamanga ndi kuwongolera kwapano, kuti ikwaniritse zofunikira za wogwiritsa ntchito.
Chithunzi 2:Servo system imapangidwa ndi PLC, drive, motor, reducer and interface.
3. Features, Ntchito ndi Mitundu ya Servo System
3.1 NKHANI ZA SERVO SYSTEM
Imafunika chida chodziwikiratu cholondola kuti ilembe liwiro lotsekeka komanso kuzungulira kwa malo.
Malingaliro Osiyanasiyana ndi Mfundo Zofananiza
Pali mitundu yosiyanasiyana ya malingaliro ndi njira zofananira. Malinga ndi mfundo zosiyanasiyana za chipangizo chodziwira kuti tikwaniritse mayankho achidziwitso ndi njira zosiyanasiyana zofananirako, pali kufananiza kwamphamvu, kufananiza kwa gawo ndi kufananitsa matalikidwe omwe amagwiritsidwa ntchito wamba.
High Performance Servo Motor
Mu zida zamakina a NC zogwirira ntchito bwino komanso zovuta zapamtunda, makina a servo nthawi zambiri amakhala akuyamba ndi kuphulika pafupipafupi. Chifukwa chake chiŵerengero cha ma torque a motor pa nthawi ya inertia chimafunika kuti chikhale chokulirapo kuti chipange mathamangitsidwe akulu kapena ma braking torque. Komanso servo motor imafunikanso kukhala ndi torque yayikulu yokwanira yotulutsa pa liwiro lotsika komanso ntchito yosalala, kuti muchepetse ulalo wapakatikati polumikizana ndi gawo losuntha lamakina.
Dongosolo Lamalamulo Lochita Bwino Ndi Liwiro Losiyanasiyana
Dongosolo lokhala ndi malamulo osiyanasiyana othamanga, omwe ndi liwiro la servo system. Kuchokera pamawonekedwe owongolera a dongosolo, makina otsekeka otsekeka a zida zamakina a CNC amatha kuwoneka ngati njira yotsekera yotsekeka yodziwikiratu yomwe ili ndi kusintha kosinthika mu chipika chakunja ndikusintha liwiro mu chipika chamkati.
Njira yeniyeni yogwirira ntchito yamkati ndikusinthira kuyika kwamalo kukhala siginecha yofananira, ndiyeno chizindikirocho chimayendetsa servo mota kuti izindikire kusamuka kwenikweni. Kusuntha kwakukulu kwa zida zamakina a CNC kumafuna magwiridwe antchito othamanga kwambiri, kotero dongosolo la servo likufunika kuti likhale loyendetsedwa bwino lomwe lili ndi liwiro lalikulu.
3.2 ZOGWIRITSA NTCHITO SERVO SYSTEM
Sinthani katundu wamphamvu kwambiri ndi chizindikiro cha malangizo otsika mphamvu.
Imayendetsedwa ndi shaft yolowera kuti ikwaniritse kufalikira kwakutali.
Pangani kusuntha kwamakina kumatsata molondola chizindikiro chamagetsi, monga kujambula ndi kuwonetsa chida, ndi zina.
3.3 MITUNDU YOSIYANA YA SERVO SYSTEM

4. Makampani Ogwiritsa Ntchito Servo System
Laser processing field
Maloboti
CNC lathe munda
Zida zopangira ma Office zopangira makina akuluakulu ophatikizika
Radar ndi magawo ena apamwamba kwambiri
5. Tsogolo la Ntchito ya Servo System
Dongosolo lodzilamulira lokha silimangokulirakulira m'malingaliro, komanso limasintha mwachangu pazida zake zogwiritsa ntchito. Pazaka 3 ~ 5 zilizonse, pamakhala zatsopano pamsika.
Makhalidwe a mota yamtundu wa AC servo ndi yofewa ndipo kutulutsa kwake sikofunikira kokha.
Stepper motor nthawi zambiri imakhala yotsegula ndipo imalephera kupeza bwino. Injini yokhayo ilinso ndi dera la velocity resonance.
Dongosolo lowongolera liwiro la PWM lili ndi kusachita bwino pakutsata malo. pafupipafupi kutembenuka liwiro lamulo ndi losavuta koma nthawi zina kulondola sikokwanira.
DC motor servo system, yokhala ndi magwiridwe antchito abwino kwambiri, yakhala ikugwiritsidwa ntchito kwambiri pamayendedwe a servo. Koma kuipa kwake, monga mawonekedwe ovuta, kutsutsana kwakukulu m'dera lakufa pa liwiro lotsika kwambiri, Ndipo burashi yobwerera kumabweretsa phokoso ndi kukonza vuto.
Maginito atsopano okhazikika a AC servo motor amakula mofulumira, makamaka pamene asintha njira yolamulira kuchoka pa square wave kupita ku sine wave. Kachitidwe kachitidwe kachitidwe kabwinoko, ndipo liwiro lake ndi lalikulu, likuchita bwino kwambiri pakuthamanga pang'onopang'ono.
