Madaidaicin servo motor yana ƙayyade daidaitaccen mai rikodin (yawan layi), wato, motar servo kanta tana da aikin aika bugun jini, kuma tana aika adadin bugun jini daidai ga kowane kusurwar juyawa, ta yadda servo drive da servo motor encoder bugun jini suka samar da echo-madaidaicin matakin, don haka yana buɗe echo-loop, don haka yana buɗe echo-loop. sarrafawa.

Low-mita halaye sun bambanta

Motar hawa: ƙaramar girgizawa mai sauƙi yana da sauƙin faruwa a ƙananan gudu. Lokacin da motar taki ke aiki cikin ƙananan gudu, gabaɗaya yakamata a yi amfani da fasahar damping don shawo kan ƙaramar girgizar ƙasa, kamar ƙara damper akan motar, ko tuƙi ta amfani da fasaha na yanki.

Motar Servo: aiki mai santsi sosai, koda a ƙananan gudu ba zai bayyana abin mamaki ba.

Tya lokaci-mita halaye na daban-daban

Motar takawa: ƙarfin fitarwa yana raguwa tare da haɓakar sauri, kuma yana raguwa sosai a cikin mafi girma, don haka matsakaicin saurin aiki gabaɗaya 300-600r/min.

Motar Servo: Matsakaicin juzu'i na yau da kullun, wato, a cikin saurin da aka ƙididdige shi (gaba ɗaya 2000 ko 3000 r/min), ƙarfin fitarwar da aka ƙididdige shi, a cikin ƙimar ƙimar da ke sama da ƙarfin wutar lantarki akai-akai.

Dinferent obalodi iya aiki

Mota mai hawa: gabaɗaya ba su da ƙarfin lodi. Takaddar mota saboda babu irin wannan nauyin nauyin nauyi, don shawo kan zaɓin wannan lokacin na rashin aiki, sau da yawa ya zama dole don zaɓar mafi girman juzu'i na motar, kuma injin baya buƙatar juzu'i mai yawa yayin aiki na yau da kullun, za a yi asarar abubuwan da suka faru.

Servo Motors: suna da ƙarfin yin nauyi mai ƙarfi. Yana da saurin wuce gona da iri da karfin juyi. Matsakaicin ƙarfinsa shine sau uku wanda aka ƙididdige shi, wanda za'a iya amfani dashi don shawo kan lokacin inertia na nauyin inertial a lokacin farawa na inertia.

Dinferent aiki yi

Motar taki: matakan sarrafa motar don sarrafa madauki, mitar farawa yana da yawa ko girma da yawa yana da wuyar rasa matakai ko toshe al'amuran tsayawa tsayin daka yana da saurin saurin harbi, don haka don tabbatar da daidaiton ikonsa, yakamata a magance matsalar tashi da faɗuwar gudu.

Motar Servo: AC servo drive tsarin don rufaffiyar madauki iko, direban iya zama kai tsaye a kan motor encoder feedback siginar samfurin, na ciki abun da ke ciki na matsayi madauki da gudun madauki, kullum ba ya bayyana a cikin stepping motor asarar matakai ko sabon abu na overshooting, da iko yi ya fi dogara.

SAyyukan amsa peed ya bambanta

Motar hawa: haɓaka daga tsayawa zuwa saurin aiki (gaba ɗaya juyi ɗari da yawa a cikin minti) yana buƙatar 200 ~ 400ms.

Motar Servo: AC servo tsarin haɓaka aikin haɓakawa ya fi kyau, daga tsayawa tsayin daka zuwa saurin ƙimar sa na 3000 r / min, 'yan millise seconds kawai, ana iya amfani da su don buƙatun saurin farawa-tsayawa da daidaiton matsayi na kula da babban filin.
