Iyo servo mota magineti inovimbisa servo motors kuita kudzora kwakaringana kumhanya uye chinzvimbo chakarurama, uye inogona kushandura chiratidzo chevoltage kuita torque uye kumhanya kutyaira chinhu chekutonga. Iyo rotor kumhanya ye servo mota inodzorwa neiyo yekuisa chiratidzo uye inogona kuita nekukurumidza.
Kubva iyo Indramat bazi reRexroth rakatanga zviri pamutemo MAC inogara magineti AC servo mota uye dhiraivha system paHannover trade fair muna 1978, izvi zvinoratidza kuti chizvarwa chitsva ichi cheAC servo tekinoroji chapinda munhanho inoshanda. Pakazosvika pakati uye pakupera kwema1980, kambani yega yega yaive yakazara yakazara yezvigadzirwa. Iyo yese servo musika iri kutendeukira kune AC masisitimu. Mazhinji emhando yepamusoro-inoshanda emagetsi servo masisitimu anoshandisa anogara magineti synchronous AC servo mota, uye mutyairi wekudzora anowanzo tora iyo yakazara dhijitari chinzvimbo servo system nekukurumidza uye kwakaringana chinzvimbo. Kune vakajairwa vagadziri vakaita seSiemens,Kollmorgen, Panasonic,Yaskawa, nezvimwewo.
Nekuda kwekushanda chaiko kweiyo servo mota, ine chinodikanwa chakaomarara nezve kushanda nemazvo uye kuita kwepamusoro, izvo zvinonyanya kuenderana nemhando yeNeodymium magineti ye servo motors. Nekuda kwehupamhi hwemhando yepamusoro yemagineti zvivakwa, Neodymium magineti inoita kuti servo mota dzigoneke nehuremu hudiki uye saizi diki zvichienzaniswa neyechinyakare magineti zvinhu, seFerrite, Alnico kana SmCo magineti.
Kune servo mota magineti, parizvino Horizon Magnetics ari kugadzira maseriji ekupedzisira magiredhi eNeodymium magineti, senge H, SH, UH, EH uye AH anotevera maitiro matatu:
1.High intrinsic coercivity Hcj: yakakwira kusvika>35kOe (>2785 kA/m) iyo inowedzera magineti demagnetizing kuramba uyezve servo mota kushanda kugadzikana.
2.Low reversible tembiricha coefficients: yakaderera kusvika α(Br)< -0.1%/ºC uye β(Hcj)< -0.5%/ºC iyo inowedzera kugadzikana kwekushisa kwemagineti uye inoita kuti servo motors ishande nekugadzikana kwepamusoro.
3.Kudzikira uremu: yakaderera kusvika 2 ~ 5mg/cm2 mune HAST yekuyedza mamiriro: 130ºC, 95% RH, 2.7 ATM, mazuva makumi maviri ayo anowedzera magineti kugwinya kuramba kuwedzera hupenyu hwehupenyu hwema servo motors.
Nekuda kweruzivo rwedu rwakapfuma mukupa vanogadzira servo mota vane magineti, Horizon Magnetics inonzwisisa iyo servo mota magineti inoda bvunzo dzakakwana kuti ive nechokwadi chekusimba kwayo, senge.demagnetization curvespakupisa kwepamusoro kuti uone kushanda kwakadzikama, PCT & SST kuti udzidze mhando yeaya yekuputira, HAST kuwana huremu, kudziyisa pakupisa kwepamusoro kuti udzidze mwero wekurasikirwa kusingadzoreki, magineti flux kutsauka kuderedza mota jitter, nezvimwe.
