Mawu oti "servo" amachokera ku liwu lachi Greek "kapolo". "Motola" amatha kumvedwa ngati galimoto yomwe imanyerereratu lamulo la chowongolera: Chizindikiro cha kuwongolera sichinatumizidwe, chovota chimayimirira; Pamene chizindikiro chowongolera chimatumizidwa, chovota chimazungulira nthawi yomweyo; Pamene kuwongolera kuwongolera kwatha, kuvunda kumatha kuyimitsa nthawi yomweyo.

Makina oyendetsa servo ndi oyendetsa micro omwe amagwiritsidwa ntchito ngati chowongolera mu chipangizo chowongolera. Ntchito yake ndikusintha chizindikiro cha magetsi mu mawonekedwe a shaplar kapena velocity ya shaft yozungulira.

Milandu ya servo yagawika m'magulu awiri: AC sesta ndi DC servo

Katundu woyambirira wa masewera a AC serO ndi ofanana ndi omwe ali ndi galimoto ya AC iC ictiction (mota asynchronous). Pali zida ziwiri zokopa wf ndi kuwongolera mphepo ndi gawo la magawo 50 ° Makina a AC seredo ali ndi mawonekedwe ogwiritsira ntchito mokhazikika, kuwongolera bwino, kuyankha mwachangu, kumapangitsa kuti pakhale 10% mpaka 15% mpaka 25% motsatana 15%.

Makina oyambira a DC servo ndi ofanana ndi omwe ali ndi galimoto yayikulu. Kuthamanga kwa Moto N = E / K1J = (UA-IARA) Mu maginito osatha DC servo mota, njira yosangalatsa imasinthidwa ndi maginito okhazikika, ndipo maginito flux φ amakhazikika. . DC servo mota ali ndi mawonekedwe abwino owongolera komanso kuyankha mwachangu.

Ubwino ndi Zovuta za DC Secro Motors

Ubwino: Kuthamangitsa pafupipafupi, torque yolimba komanso yothamanga kwambiri, mfundo zosavuta, zosavuta kugwiritsa ntchito, komanso mtengo wotsika mtengo.

Zovuta: Kubera kwa Brashi, Kuthamanga Kwambiri, Kukaniza Kowonjezereka, ndi Kuvala Malo Okwanira (OSATI DEW (Oyenera ndi Malo Ophulika)

Ubwino ndi Zovuta za Mac Sefero Mota

Ubwino: Kuthamanga Kwambiri Kuthamanga, Kuwongolera kosalala konsekonse, pafupifupi osakhala ndi chiwongola dzanja, kuwongolera kwamphamvu, kukonzanso fumbi -

Zovuta: Kuwongolera kuli kovuta, magawo oyendetsa amafunika kusintha malo kuti adziwe magawo a pid, ndipo malumikizidwe ambiri amafunikira.

Makolo a DC servo amagawidwa m'malo osenda komanso osasunthika

Mosaka zotsekemera ndizotsika mtengo, zosavuta poyambira torque, kutalika kwambiri pakuthana ndi ma elekitikiti, koma nthawi zambiri zimagwiritsidwa ntchito posungira, nthawi zambiri amagwiritsa ntchito nthawi wamba - nthawi zachitukuko.

Mosaka zopanda pake ndizochepa kwambiri kukula ndi kuwala kolemera, kutalika kotulutsa, motalika kokhazikika, kukonzanso kwamphamvu, kutentha kochepa komanso moyo wambiri.

Maso a AC seerola ali nawonso osakake, omwe amagawidwa mozama ndi zidenzo. Pakadali pano, mosangalatsa ma synchronous nthawi zambiri amagwiritsidwa ntchito poyendetsa. Njira zamagetsi ndizazikulu, mphamvu zitha kukhala zazikulu, zomwe zimakhala ndi zikuluzikulu, kuthamanga kwakukulu kumakhala kotsika, ndipo liwiro limawonjezeka ndi kuchuluka kwa mphamvu. Yunifolomu yochokera, yoyenera kutsika-yosalala yoyenda bwino.

Rotor mkati mwa servo mota ndi maginito osatha. Dalaivala akuwongolera U / V / W Atatu - gawo lamagetsi kuti apange munda wamagetsi. Rotor imazungulira pansi pa zojambula zamagetsi. Nthawi yomweyo, encorder yomwe imabwera ndi mota imapereka chizindikiro kwa woyendetsa. Makhalidwe amafaniziridwa ndi kusintha ngodya ya kuzungulira kwa color. Kulondola kwa magalimoto a servo kumatengera kulondola kwa malo olemba (chiwerengero cha mizere).

Kodi galimoto ya servo ndi chiyani? Kodi pali mitundu ingati? Kodi ndi ziti zomwe zikugwira ntchito?

Yankho: Makina owotchera, omwe amadziwikanso kuti wamkulu, amagwiritsidwa ntchito ngati wogwira ntchito mu dongosolo la magetsi kuti atembenukire kumbali kapena ma velocity a velocity pa shaft.

Milandu ya servo imagawidwa m'magulu awiri: DC ndi ma ac sefeola. Makhalidwe awo akulu ndikuti palibe chodzisinthana pomwe magetsi a siginecha ndi zero, ndipo liwiro limatsika liwiro la lifolome ndi kuwonjezeka kwa udzi.

Kodi pali kusiyana kotani mukamayendetsa pakati pa ma ac seva ndi zofufumitsa zopanda pake?

Yankho: Kuchita kwa ma ac semedo kuli bwino, chifukwa servo ya AC imayendetsedwa ndi funde la sine ndi torque ngwazi ndizochepa; Pomwe Scarsed DC servo imayendetsedwa ndi funde la trapezoidal. Koma zotchinga za DC Servo ndizosavuta komanso zotsika mtengo.

Kukula kwachangu kwa maginito okhazikika magnet drive ag Ndi chitukuko cha ukadaulo, zamatsenga zamatsenga zam'madzi zatha, ndipo opanga zamagetsi otchuka m'maiko osiyanasiyana apitilizabe kuyika mndandanda watsopano wa AC Spequo Motors ndi Servo. Dongosolo la AC se senta lasandulika chitukuko chachikulu cha servo yodziwika bwino kwambiri, yomwe imapangitsa DC servo ikukumana ndi mavuto ochotsedweratu.

Poyerekeza ndi madontho a DC servo, maginito osatha a Ac semero mota ali ndi zabwino zotsatirazi:

Rashing burashi ndi chort, opaleshoniyo ndi yodalirika komanso kukonza.

(2) Zolemba zowombera zimachepa kwambiri.

⑶ Batia ndi yaying'ono, ndipo kachitidweko kamayankha mwachangu.

Kuthamanga kwambiri komanso kukwera kwakukulu kwabwino.

Kukula kwa kukula kwa ma ⑸small pansi pa mphamvu yomweyo.

Mfundo ya servo

Kapangidwe kake kake ka AC serO mota ndendende ndi chimodzimodzi ndi momwe agawanidwe agalu a Splynnous -phase. Chizindikirocho chili ndi minda iwiri yokhala ndi kusiyana kwa 90 °, imodzi ndiye yolumikizira rf yamagetsi ya magetsi; Wina ndiye chiwongolero chomwe chimalumikizidwa l, chomwe chimalumikizidwa ndi magetsi owongolera uc. Chifukwa chake kuwola ac servo kumatchedwanso maofesi awiri a servo.

Rotor of Ac serdo mota khola, koma kuti apange morengo mota Pakadali pano pali mitundu iwiri ya zojambulajambula zomwe zimagwiritsidwa ntchito kwambiri: imodzi ndi nyama ya gologolo - yopanda maongoletsedwe - owongolera okhazikika opangidwa ndi zida zapamwamba. Pofuna kuchepetsa nthawi ya matenda a rotor, rotor imapangidwa yofanda; Wina ndi chikho cha Hollowo-chowoneka chopangidwa ndi aluminiyamu chiloya, khoma la chikho ndi lokha 0,2 -0.3mm, nthawi ya rotor yocheperako, yankho lake ndi lokhazikika.

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 polowera maginito ozungulira. Katunduyu akakhala nthawi zonse, kuthamanga kwagalimoto kumasintha ndi ukulu wa magetsi oyendetsa. Gawo la magetsi owongolera ali osiyana, morengo ya servo idzasinthidwa.

Ngakhale mfundo yogwira ntchito ya ac servo ndi yofanana ndi ya Captor - And Anlorronous - mota rotor, kukana kwa chozungulira ndi chachikulu kuposa izi. Chifukwa chake, poyerekeza ndi capicator, mota asynchronous, morengo mota ali ndi mitundu itatu ya mchere:

1. Chimbudzi chachikulu choyambira: chifukwa cha kukana kwakukulu korona, mawonekedwe a torque (mawonekedwe opanga) ali pafupi ndi mzere, ndipo 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 yayikulu yogwira ntchito: Ntchito yolimba komanso phokoso lotsika. [/ p] [P = 30, 2, kumanzere] 3. Palibe chodzisintha tokha: Ngati servo mota ntchito imataya kuthamanga nthawi yomweyo.

Kodi "Kutumiza Kosanja Micro Motion" ndi chiyani?

"Kutumiza mwachidule micro mota" kumatha kukwaniritsa malangizo pafupipafupi m'dongosolo, ndikuyendetsa makina a servo kuti amalize ntchito yomwe ikuyembekezeka, ndipo ambiri aiwo amatha kukwaniritsa zofunikira zotsatirazi:

1. Imatha kuyamba, kuyimitsidwa, kuthyoka, sinthani ndikuthamanga pa liwiro lotsika, ndipo ali ndi mphamvu yayikulu, yolimba kwambiri.

2. Kutha kuyankha mwachangu, torque yayikulu, mphindi yaying'ono ya inertia ndi nthawi yochepa.

3.

4. Kudalirika kwakukulu komanso kulondola kwambiri.

Gulu, kapangidwe kake ndi magwiridwe antchito "mogwirizana ndi micro mota"
