Mutyairi anodzora U/V/W matatu-phase magetsi kuti aumbe electromagnetic field, uye rotor inotenderera pasi pechiito chemagnetic field.Panguva imwecheteyo, iyo encoder yemota inodzosera chiratidzo kune drive.Mutyairi anofananidza kukosha kwemhinduro nechinangwa chekugadzirisa rotor rotation angle.Kururamisa kwe servo motor kunoenderana nekururama (nhamba yemitsara) ye encoder.Yakakamurwa kuita DC uye AC servo mota.Chinhu chayo chikuru ndechekuti kana chiratidzo chemagetsi chiri zero, hapana chinotenderera chiitiko, uye kumhanya kunoderera zvakaenzana nekuwedzera kwe torque.Nzwisisa iyo yakakosha chimiro cheiyo servo mota, tenzi nheyo yekushanda kwayo, hunhu hwekushanda uye hunhu, uye nguva dzekushandisa, kuitira kuti usarudze uye uishandise nemazvo.Ndeapi maitiro eiyo nheyo yekushanda ye servo mota?
1. Chii chinonzi servo mota?
Servo motors, inozivikanwawo seactuator motors, ndeye ma actuators mu control system inoshandura masaini emagetsi kuita makona kana kumhanya pane shaft kutyaira chinhu chekudzora.Servo mota, inozivikanwawo seye Executive mota, chinhu chekutonga mune otomatiki kudzora sisitimu inoshandura iyo yakagamuchirwa chiratidzo chemagetsi kuita angular displacement kana angular velocity kubuda pane mota shaft.
Yakakamurwa kuita DC uye AC servo mota.Chinhu chayo chikuru ndechekuti kana chiratidzo chemagetsi chiri zero, hapana chinotenderera chiitiko, uye kumhanya kunoderera zvakaenzana nekuwedzera kwe torque.
2. Maximum maitiro e servo motor
Kana paine chiratidzo chekutonga chinopinda, iyo servo mota inotenderera;kana pasina kupinza chiratidzo chekudzora, chinomira kutenderera.Iko kumhanya uye kutungamira kweiyo servo mota inogona kushandurwa nekushandura ukuru uye chikamu (kana polarity) yekudzora voltage.Kubva kuma1980, nekuvandudzwa kwemasekete akabatanidzwa, tekinoroji yemagetsi emagetsi uye tekinoroji yekumhanyisa AC, tekinoroji yekusingaperi AC servo drive tekinoroji yakafambira mberi.Vagadziri vemotokari vane mukurumbira munyika dzakasiyana siyana vakatanga yavo nhepfenyuro yeAC servo motors uye servo drives, uye ivo vari kugara vachivandudza nekuvandudza.
AC servo system yave iyo huru yekuvandudza nzira yemazuva ano yepamusoro-inoshanda servo system, inoita kuti yekutanga DC servo system itarise dambudziko rekubviswa.Mushure memakore ekuma1990, kushambadzira AC servo masisitimu kutenderera pasirese kwaifambiswa nemadhijitari akazara anodzora sine wave motors.Iko kuvandudzwa kweAC servo madhiraivha mumunda wekutapurirana kuri kuchinja nezuva rega rega.
3. Kuenzaniswa neakajairika mota, servo mota dzine zvinotevera maitiro
(1) The speed regulation range yakakura.Sezvo magetsi ekudzora achichinja, kumhanya kweiyo servo mota inogona kuramba ichigadziriswa pamusoro pehupamhi.
(2) Iyo rotor inertia idiki, saka inogona kutanga nekumira nekukurumidza.
(3) Simba rekutonga idiki, kuwanda kwehuwandu hwakasimba, uye kuvimbika kwakanaka.
4. Yakajairika kushandiswa kwe servo mota mune otomatiki control system
Siemens, Kollmorgen, Panasonic uye Yaskawa
Ndeapi maitiro ekushanda e servo motors?Kupfupisa, AC servo masisitimu akakwirira kune anotsika mota munzira dzakawanda.Nekudaro, mune mamwe mamiriro asingade kudiwa, stepper motors anowanzo shandiswa se actuator mota.Naizvozvo, mukugadzira dhizaini yekudzora sisitimu, zvinodikanwa kunyatso funga nezvekutonga zvinodiwa, mari uye zvimwe zvinhu kusarudza yakakodzera control mota.
