Kugwira Mfundo Ya AC Sestaro Motola:
Makina a AC seervo alibe magetsi, pali maginisi okhazikika omwe amapangidwa ndi kukolola komwe kumachitika mu Scor, ndipo rotor imakhala yokhazikika. Pakakhala magetsi owongolera, mphamvu yamagetsi yozungulira imapangidwa mu schoor, ndipo rotor imazungulira mbali yoyambira maginito ozungulira. Katunduyu akakhala nthawi zonse, kuthamanga kwagalimoto kumasintha ndi ukulu wa magetsi oyendetsa. Gawo la magetsi owongolera ali osiyana, ma ac semero amabwerera. Ngakhale mfundo yogwira ntchito ya ac servo ili yofanana ndi gawo la gawo limodzi logawanika kwa gawo la asynchronous, kukana kwa rotor lakale kuli lalikulu kuposa lazotsatira. Chifukwa chake, poyerekeza ndi makina amodzi a asynchronous, morengo mota ali ndi zinthu zitatu zamafuta:
1. Torque yayikulu
Chifukwa cha kukana kwakukulu kwa korona, mawonekedwe ake a torque amawonetsedwa mu curve 1 mu Chithunzi 3, zomwe ndizosiyana ndi zolimba za torvity. Itha kupangitsa kuti zikhale zovuta zikuluzikulu s0> 1, zomwe sizimangopanga chimbudzi cha chithumwa (cha makina) pafupi ndi mzere, komanso ali ndi chiwongola dzanja chokulirapo. Chifukwa chake, pamene wotsutsa ali ndi magetsi oyendetsa, chovota chimazungulira nthawi yomweyo, chomwe chimakhala ndi mawonekedwe oyambira ndikumva chidwi kwambiri.
2. Mitundu yogwira ntchito yayikulu
3. Palibe kuzungulira chodabwitsa
Kwa servo mota nthawi yayitali, bola ngati magetsi oyendetsa amatayika, mota adzasiya kuthamanga nthawi yomweyo. Maola a servolu atataya magetsi owongolera, ali mu ntchito imodzi. Chifukwa cha kukana kwakukulu kwa rotor, mikhalidwe iwiri ya torque (t1-s1, t2-s2-s2 yopangidwa ndi maginito awiri) Curve) Mphamvu yotulutsa ya ma ac seva nthawi zambiri imakhala 0.1-100w. Pamene magetsi pafupipafupi ndi 50hz, mphamvu ya volipi ndi 36V, 110V, 220, 380v; Mphamvu pafupipafupi ndi 400hz, magetsi 20V, 26V, 36V, 115V ndi zina zambiri. Makina a ac seva amayenda bwino ndi phokoso lotsika. Koma chowongolera chowongolera sichikukhala chopanda mzere, ndipo chifukwa kukana ku Roma ndi kwakukulu, kutayika kwake, ndipo mphamvu zake zimakhala zochepa, poyerekeza ndi zochulukirapo komanso zokwanira, motero ndioyenera Kwa makina ochepa oyendetsa magetsi a 0.5-100w.
Chachiwiri, kusiyana pakati pa acquo Motor ndi DC servo mota:
Makolo a DC servo amagawidwa motalika komanso osasunthika. Mosata otsika mtengo pamtengo, wosavuta pakuyamba, kwakukulu pakuyamba, ndipo amasavuta kuwongolera, koma ndiosavuta kuwongolera, koma ndikosavuta kuwongolera, koma ndizosavuta kusokoneza, ndipo ndi zofunikira zamagetsi, ndikukhala ndi zofunikira kwa chilengedwe. Chifukwa chake, itha kugwiritsidwa ntchito popanga mafakitale komanso zachikhalidwe zomwe zimakonda mtengo. Motchi yopanda zopumira ndi yaying'ono kukula, kuwala kolemera, kwakukulu pakutulutsa, poyankha mwachangu, zazing'ono kwambiri, zosalala mosinthana ndi zokhazikika mu torqua. Chowongolera ndichovuta, ndipo nkosavuta kuzindikira anzeru. Njira yake yamagetsi imasinthasintha, ndipo imatha kukhala yosinthira mitengo kapena sine. Motor ndi yopanda ulemu, imakhala ndi phindu lalikulu, kutentha kochepa, kutentha kotsika, moyo wautali, ndipo ungagwiritsidwe ntchito m'malo osiyanasiyana.
Maso a AC seerola amagawika mozama komanso mota. Pakadali pano, mosangalatsa ma synchronous nthawi zambiri amagwiritsidwa ntchito poyendetsa. Mitundu yake yamagetsi ndi yayikulu ndipo imatha kukwaniritsa mphamvu yayikulu. Kuthamanga kwakukulu, kumathamanga kwambiri movota, ndikuchepetsa mwachangu ngati mphamvu ikuwonjezeka. Chifukwa chake, ndizoyenera kugwiritsa ntchito zomwe zimayenda bwino pa liwiro lotsika.
Rotor mkati mwa servo mota ndi maginito osatha. Magetsi a U / V / W Atatu omwe amayendetsedwa ndi driver amapanga munda wamagetsi. Rotor imazungulira pansi pa zojambula zamagetsi. Nthawi yomweyo, malo osungira nyama amatenga chizindikiro kwa woyendetsa. Makhalidwe amafaniziridwa ndi kusintha ngodya yomwe rotor imatembenukira. Kulondola kwa magalimoto a servo kumatengera kulondola (chiwerengero cha mizere) ya encoder.
Ndi kupita patsogolo kosalekeza kwa makina ogwiritsa ntchito mafakitale, kufunikira kwa mapulogalamu a tokha ndi zida zankhondo kumangokhala. Pakati pawo, msika wa loboti wa patali wa matampani akhala akukula mosasunthika, dziko langa lakhala msika waukulu kwambiri padziko lonse lapansi. Nthawi yomweyo, imayendetsa molunjika pamsika kwa Servo Systems. Pakadali pano, ac ndi dc servo mota torque, torque yayikulu komanso yotsika irtia amagwiritsidwa ntchito kwambiri m'malo maloboti ogulitsa mafakitale. Motors ena, monga ma moto a ac serors ndi ozungulira, idzagwiritsidwanso ntchito malo obowoleza mafakitale malinga ndi zofunika pa ntchito.
