Mfundo yogwiritsira ntchito AC servo motor:
Pamene AC servo galimoto alibe ulamuliro voteji, pali kokha pulsating maginito munda kwaiye ndi chisangalalo mapiringidzo mu stator, ndi ozungulira ndi kuyima.Pakakhala mphamvu yamagetsi, mphamvu yamagetsi yozungulira imapangidwa mu stator, ndipo rotor imazungulira motsatira njira yozungulira maginito.Pamene katundu ali wokhazikika, liwiro la galimoto limasintha ndi kukula kwa mphamvu yamagetsi.Pamene gawo la magetsi olamulira likutsutsana, AC servo The motor idzasintha.Ngakhale mfundo yogwira ntchito ya AC servo motor ndi yofanana ndi ya gawo limodzi la gawo limodzi la asynchronous motor, kukana kwa rotor wakale ndikokulirapo kuposa komaliza.Chifukwa chake, poyerekeza ndi injini yamakina asynchronous, injini ya servo ili ndi mawonekedwe atatu:
1. Torque yayikulu yoyambira
Chifukwa cha kukana kwakukulu kwa rotor, mayendedwe ake amakokedwe amawonetsedwa pamapindikira 1 pachithunzi 3, chomwe mwachiwonekere ndi chosiyana ndi makokedwe amtundu wa 2 wama motors wamba asynchronous.Itha kupangitsa kutsika kofunikira kwambiri S0> 1, zomwe sizimangopangitsa mawonekedwe a torque (mawonekedwe a makina) kukhala pafupi ndi mzere, komanso amakhala ndi torque yayikulu.Choncho, pamene stator ili ndi mphamvu yowonongeka, rotor imazungulira nthawi yomweyo, yomwe ili ndi makhalidwe oyambira mofulumira komanso kutengeka kwakukulu.
2. Wide ntchito osiyanasiyana
3. Palibe chozungulira chodabwitsa
Kwa injini ya servo ikugwira ntchito bwino, bola mphamvu yowongolera itatayika, injiniyo imasiya kuthamanga nthawi yomweyo.Pamene injini ya servo itaya mphamvu yolamulira, ili mu gawo limodzi la ntchito.Chifukwa cha kukana kwakukulu kwa rotor, mawonekedwe awiri a torque (T1-S1, T2-S2 ma curve) amapangidwa ndi magawo awiri ozungulira maginito omwe amazungulira mbali zosiyana mu stator ndi machitidwe a rotor) ndi mawonekedwe a torque (TS) curve) Mphamvu yotulutsa ya AC servo motor nthawi zambiri imakhala 0.1-100W.Pamene mphamvu pafupipafupi ndi 50Hz, ma voltages ndi 36V, 110V, 220, 380V;pamene mphamvu pafupipafupi ndi 400Hz, ma voltages ndi 20V, 26V, 36V, 115V ndi zina zotero.The AC servo motor imayenda bwino ndi phokoso lochepa.Koma mawonekedwe owongolera ndi osagwirizana, ndipo chifukwa kukana kwa rotor ndikwambiri, kutayika kwake ndikwambiri, ndipo magwiridwe ake ndi otsika, poyerekeza ndi mota ya DC servo yamphamvu yomweyi, ndi yayikulu komanso yolemetsa, chifukwa chake ndiyoyenera. kwa machitidwe ang'onoang'ono owongolera mphamvu a 0.5-100W.
Chachiwiri, kusiyana pakati pa AC servo mota ndi DC servo mota:
Ma DC servo motors amagawidwa kukhala ma brushed ndi brushless motors.Ma motors opukutidwa ndi otsika mtengo, osavuta kupanga, akulu poyambira ma torque, okulirapo pamayendedwe othamanga, osavuta kuwongolera, ndipo amafunikira kukonza, koma ndi osavuta kuwasamalira (m'malo mwa maburashi a kaboni), amapanga kusokoneza kwa ma electromagnetic, ndipo amakhala ndi zofunikira pa chilengedwe.Chifukwa chake, itha kugwiritsidwa ntchito m'mafakitale ndi zochitika zapagulu zomwe zimakhudzidwa ndi mtengo.Galimoto yopanda brush ndi yaying'ono, yopepuka, yopepuka, yotulutsa mwachangu, yothamanga kwambiri, yothamanga kwambiri, yaying'ono mu inertia, yosalala mozungulira komanso yokhazikika mu torque.Kuwongolera ndikovuta, ndipo ndikosavuta kuzindikira luntha.Njira yake yosinthira zamagetsi ndi yosinthika, ndipo imatha kukhala masikweya mafunde kapena kusintha kwa sine wave.Galimotoyo ndiyopanda kukonza, imakhala yogwira ntchito kwambiri, kutentha kwapang'onopang'ono, ma radiation otsika a electromagnetic, moyo wautali, ndipo itha kugwiritsidwa ntchito m'malo osiyanasiyana.
Ma AC servo motors amagawidwa kukhala ma synchronous ndi asynchronous motors.Pakalipano, ma synchronous motors amagwiritsidwa ntchito poyendetsa kayendedwe.Mphamvu zake zosiyanasiyana ndi zazikulu ndipo zimatha kukwaniritsa mphamvu zazikulu.Inertia yayikulu, yotsika kwambiri yothamanga kwambiri, ndipo imachepa kwambiri pamene mphamvu ikuwonjezeka.Choncho, ndi oyenera ntchito zomwe zimayenda bwino pa liwiro lotsika.
Rotor mkati mwa servo motor ndi maginito okhazikika.Magetsi a magawo atatu a U / V / W omwe amayendetsedwa ndi dalaivala amapanga gawo lamagetsi.Rotor imazungulira pansi pakuchita kwa maginito awa.Nthawi yomweyo, encoder ya injini imabwezeretsanso chizindikiro kwa dalaivala.Makhalidwe amafananizidwa ndi kusintha kozungulira komwe rotor imatembenukira.Kulondola kwa injini ya servo kumadalira kulondola (chiwerengero cha mizere) cha encoder.
Ndikupita patsogolo kosalekeza kwa mafakitale opanga makina, kufunikira kwa mapulogalamu a automation ndi zida za hardware kumakhalabe kwakukulu.Pakati pawo, msika wamaloboti akunyumba ukukulirakulira, ndipo dziko langa lakhala msika wofunikira kwambiri padziko lonse lapansi.Nthawi yomweyo, imayendetsa mwachindunji kufunikira kwa msika kwa machitidwe a servo.Pakadali pano, ma AC ndi DC servo motors okhala ndi torque yayikulu, torque yayikulu ndi inertia yotsika amagwiritsidwa ntchito kwambiri m'maloboti amakampani.Ma motors ena, monga ma AC servo motors ndi stepper motors, azigwiritsidwanso ntchito m'maloboti akumafakitale malinga ndi zofunikira zosiyanasiyana.
