Ozibuthe bezimoto ze-servo baqinisekisa ama-servo motors ukwenza isilawuli sibe nesivinini esinembile nokunemba kwesikhundla, futhi bangaguqula isignali ye-voltage ibe yi-torque nesivinini sokushayela into yokulawula.Isivinini se-rotor se-servo motor silawulwa isignali yokufaka futhi singasabela ngokushesha.
Kusukela igatsha le-Idramat lase-Rexroth lethule ngokusemthethweni i-MAC ezinzile uzibuthe we-AC servo motor and drive system embukisweni wezohwebo wase-Hannover ngo-1978, lokhu kuphawula ukuthi lesi sizukulwane esisha sobuchwepheshe be-AC servo sesingene esigabeni esisebenzayo.Maphakathi nawo-1980 ngasekupheleni, inkampani ngayinye yayinochungechunge oluphelele lwemikhiqizo.Yonke imakethe ye-servo iphendukela kumasistimu e-AC.Iningi lezinhlelo ze-servo zikagesi ezisebenza kahle kakhulu zisebenzisa uzibuthe unomphela we-AC servo motor, futhi umshayeli olawulayo ngokuvamile wamukela uhlelo oluphelele lwe-servo lwesimo sedijithali ngokuma okusheshayo nokunembile.Kukhona abakhiqizi abajwayelekile abafana no-Siemens,I-Kollmorgen, Panasonic,Yaskawa, njll.
Ngenxa yomsebenzi onembile we-servo motor, inesidingo esiqinile mayelana nokusebenza ngokunemba nokusebenza okuphezulu, okuncike kakhulu kwikhwalithi yamazibuthe e-Neodymium yama-servo motors.Ngenxa yobubanzi bezakhiwo eziphakeme kazibuthe, uzibuthe we-Neodymium wenza ama-servo motors enzeke ngesisindo esiphansi kanye nosayizi omncane uma kuqhathaniswa nezinto ezivamile kazibuthe, njengozibuthe beFerrite, Alnico noma i-SmCo.
Komazibuthe bezimoto ze-servo, njengamanje i-Horizon Magnetics ikhiqiza uchungechunge lwamabanga aphezulu wozibuthe be-Neodymium, njengo-H, SH, UH, EH no-AH anezici ezintathu ezilandelayo:
1.Ukuqina okuphezulu kwe-intrinsic Hcj: ukuphakama kuya ku->35kOe (>2785 kA/m) okwandisa ukumelana nozibuthe demagnetizing bese kuba ukuqina kokusebenza kwe-servo motor
2.Ama-coefficients okushisa abuyiselekeka aphansi: aphansi ukuya ku-α(Br)< -0.1%/ºC kanye no-β(Hcj)< -0.5%/ºC akhuphula ukuzinza kwezinga lokushisa uzibuthe futhi aqinisekise ukuthi ama-servo motors asebenze ngokuzinza okuphezulu
3.Ukuncipha kwesisindo okuphansi: kuphansi kuye ku-2~5mg/cm2 esimweni sokuhlola i-HAST: 130ºC, 95% RH, 2.7 ATM, izinsuku ezingama-20 okwandisa ukumelana nokugqwala kozibuthe ukuze kunwetshwe isikhathi sokuphila sama-servo motors
Ngenxa yolwazi lwethu olucebile ekuhlinzekeni abakhiqizi bezimoto ze-servo ngozibuthe, i-Horizon Magnetics iyaqonda ukuthi uzibuthe we-servo motor udinga ukuhlolwa okuphelele ukuze kuqinisekiswe ikhwalithi yayo eqinile, njengokuthidemagnetization curvesemazingeni okushisa aphezulu ukuze ubone ukusebenza kokuqina kokusebenza, i-PCT ne-SST ukuze ufunde ikhwalithi yezendlalelo zokuhlanganisa, i-HAST ukuthola ukuncipha kwesisindo, ukushisa ezingeni lokushisa eliphezulu ukuze ufunde izinga lokulahlekelwa okungenakuhlehliswa, ukuphambuka kwe-flux magnetic ukunciphisa i-motor jitter, njll.
