Kushanda musimboti we AC servo mota:
Kana iyo AC servo mota isina simba rekudzora, pane chete iyo inopuruzira magineti inogadzirwa nemhepo inosimudzira mu stator, uye rotor yakamira.Kana paine simba rekutonga, inotenderera magineti inogadzirwa mu stator, uye rotor inotenderera ichienda kune inotenderera inotenderera magineti.Kana mutoro uchigara, kumhanya kwemota kunoshanduka nehukuru hwemagetsi ekudzora.Kana chikamu cheiyo control voltage yakatarisana, iyo AC servo Iyo mota inodzokera kumashure.Kunyangwe iyo nheyo yekushanda ye AC servo mota yakafanana neiyo yekupatsanurwa-chikamu chimwe-chikamu asynchronous mota, iyo rotor kuramba kweiyo yekutanga yakakura kupfuura iyo yekupedzisira.Naizvozvo, zvichienzaniswa neasynchronous mota imwechete-muchina, iyo servo mota ine matatu anooneka maficha:
1. Yakakura kutanga torque
Nekuda kwehombe yerotor kuramba, torque yayo hunhu curve inoratidzwa mu curve 1 muFigure 3, izvo zviri pachena kuti zvakasiyana kubva kune torque hunhu curve 2 yeakajairwa asynchronous motors.Inogona kuita yakakosha kutsvedza mwero S0> 1, iyo isingaite chete torque hunhu (mechanicha maitiro) padhuze nemutsara, asi zvakare ine yakakura yekutanga torque.Nokudaro, kana stator ine simba rekutonga, rotor inotenderera pakarepo, iyo ine maitiro ekukurumidza kutanga uye kunzwisisika kwakanyanya.
2. Wide kushanda siyana
3. Hapana chiitiko chekutenderera
Kune servo mota mune yakajairika kushanda, chero bedzi iyo control voltage yarasika, mota inomira kumhanya nekukasira.Kana iyo servo mota inorasa simba rekutonga, iri mune imwe-chikamu chekushanda mamiriro.Nekuda kwekupokana kukuru kwe rotor, iwo maviri torque maitiro (T1-S1, T2-S2 curves) anogadzirwa nemagineti maviri anotenderera anotenderera akatarisana mu stator uye kuita kwe rotor) uye synthetic torque maitiro (TS. curve) Simba rekubuda reAC servo mota rinowanzo 0.1-100W.Kana iyo frequency yesimba iri 50Hz, iwo magetsi ari 36V, 110V, 220, 380V;kana frequency yesimba iri 400Hz, mavolts ari 20V, 26V, 36V, 115V zvichingodaro.Iyo AC servo mota inomhanya zvakanaka neruzha rwakaderera.Asi hunhu hwekudzora hahuna mutsara, uye nekuti iyo rotor kuramba yakakura, kurasikirwa kwakakura, uye kushanda kwacho kwakadzikira, zvichienzaniswa neiyo DC servo mota yemhando imwe chete, yakakura uye inorema, saka yakakodzera chete. kune madiki masimba ekudzora masisitimu e0.5-100W.
Chechipiri, musiyano pakati pe AC servo mota uye DC servo mota:
DC servo mota dzakakamurwa kuita brushed uye brushless mota.Mabhurashi mota ane mutengo wakaderera, akareruka muchimiro, akakura mukutanga torque, yakafara mukumhanya kudzora renji, nyore kudzora, uye inoda gadziriso, asi ari nyore kuchengetedza (tsiva kabhoni mabhurashi), anogadzira kukanganiswa kwemagetsi, uye ane zvinodiwa zvakatipoteredza.Naizvozvo, inogona kushandiswa mune zvakajairika maindasitiri uye ehurumende zviitiko zvine hanya nemutengo.Iyo brushless mota idiki muhukuru, yakareruka muhuremu, yakakura mukubuda, inokurumidza mukupindura, yakakwirira mukumhanya, diki inertia, yakatsetseka mukutenderera uye yakagadzikana mu torque.Kudzora kwakaoma, uye zviri nyore kuona hungwaru.Yayo yemagetsi commutation nzira inochinjika, uye inogona kuita square wave commutation kana sine wave commutation.Iyo mota haina kugadzirisa, ine hunyanzvi hwepamusoro, tembiricha yakaderera yekushandisa, yakaderera magetsi emagetsi, hupenyu hurefu, uye inogona kushandiswa munzvimbo dzakasiyana siyana.
AC servo mota dzakakamurwa kuita synchronous uye asynchronous mota.Parizvino, masynchronous motors anowanzo shandiswa mukufambisa kudzora.Simba rayo rakakura uye rinogona kuwana simba guru.Huru inertia, yakaderera yakanyanya kutenderera kumhanya, uye inoderera nekukurumidza sezvo simba rinowedzera.Naizvozvo, inokodzera maapplication anomhanya zvakanaka nekumhanya kwakaderera.
Iyo rotor mukati meiyo servo mota ndeye isingaperi magineti.Magetsi eU/V/W matatu-chikamu anodzorwa nemutyairi anoumba munda wemagetsi.Iyo rotor inotenderera pasi pechiito cheiyo magnetic field.Panguva imwecheteyo, iyo encoder yemota inodzosera chiratidzo kumutyairi.Values inofananidzwa kugadzirisa kona iyo rotor inotenderera.Kurongeka kweiyo servo mota kunoenderana nekurongeka (nhamba yemitsara) yeencoder.
Nekuenderera mberi kwekufambira mberi kwemaindasitiri otomatiki, kudiwa kweautomation software uye hardware michina inoramba yakakwirira.Pakati pavo, misika yemarobhoti epamba yanga ichikura zvishoma nezvishoma, uye nyika yangu yave musika mukuru wepasi rose unodiwa.Panguva imwecheteyo, inofambisa zvakananga kudiwa kwemusika kune servo system.Parizvino, AC uye DC servo motors ine yakakwirira yekutanga torque, yakakura torque uye yakaderera inertia inoshandiswa zvakanyanya mumarobhoti eindasitiri.Mamwe mamotor, akadai seAC servo motors uye stepper motors, anozoshandiswawo mumarobhoti eindasitiri zvinoenderana nezvinodiwa zvakasiyana zvekushandisa.
