Motocin servo suna tabbatar da injunan servo don yin daidaitaccen saurin sarrafawa da daidaiton matsayi, kuma yana iya canza siginar wutar lantarki zuwa juzu'i da sauri don fitar da abin sarrafawa.Gudun rotor na servo motor ana sarrafa shi ta siginar shigarwa kuma yana iya amsawa da sauri.
Tun lokacin da reshen Indramat na Rexroth ya ƙaddamar da tsarin MAC na dindindin na magnet AC servo da tsarin tuki a bikin baje kolin kasuwanci na Hannover a 1978, wannan ke nuna cewa wannan sabon ƙarni na fasahar AC servo ya shiga mataki mai amfani.A tsakiyar tsakiyar da ƙarshen 1980s, kowane kamfani yana da cikakken jerin samfuran.Duk kasuwar servo tana juyawa zuwa tsarin AC.Yawancin manyan ayyuka na servo na lantarki suna amfani da injin maganadisu na dindindin na AC servo motor, kuma direban sarrafawa galibi yana ɗaukar cikakken tsarin servo na dijital tare da sauri da daidaitaccen matsayi.Akwai masana'anta na yau da kullun kamar Siemens,Kolmorgen, Panasonic,Yaskawa, da dai sauransu.
Saboda ingantaccen aikin injin servo, yana da ƙaƙƙarfan buƙatu game da daidaiton aiki da babban aiki, wanda galibi ya dogara da ingancin magnetin Neodymium don injin servo.Saboda babban kewayon mafi girma Magnetic Properties, Neodymium Magnetic sa servo Motors yiwu tare da ƙananan nauyi da karami size idan aka kwatanta da na gargajiya Magnetic kayan, kamar Ferrite, Alnico ko SmCo maganadiso.
Domin servo motor maganadiso, a halin yanzu Horizon Magnetics suna samar da serials na manyan maki na Neodymium maganadiso, kamar H, SH, UH, EH da AH tare da wadannan halaye uku:
1.High intrinsic coercivity Hcj: babba zuwa> 35kOe (> 2785 kA / m) wanda ke ƙara ƙarfin juriya na haɓakawa sannan kuma servo motor aiki kwanciyar hankali.
2.Low reversible zazzabi coefficients: low to α (Br) <-0.1%/ºC da β (Hcj) <-0.5%/ºC wanda ke ƙara ƙarfin zafin jiki na magnet kuma yana tabbatar da servo Motors don yin aiki tare da kwanciyar hankali mafi girma.
3.Low nauyi asara: low zuwa 2 ~ 5mg / cm2 a HAST gwajin yanayin: 130ºC, 95% RH, 2.7 ATM, 20 days wanda qara maganadiso lalata juriya don tsawanta rayuwa lokaci na servo Motors.
