Limmanete tsa servo motor li netefatsa li-motor tsa servo ho etsa hore taolo e be lebelo le nepahetseng le boemo bo nepahetseng, 'me e ka fetolela lets'oao la motlakase hore e be torque le lebelo ho khanna ntho ea taolo. Lebelo la rotor la servo motor le laoloa ke lets'oao la ho kenya 'me le ka arabela kapele.
Ho tloha ha lekala la Indramat la Rexroth le tsebahatsa ka molao tsamaiso ea MAC ea magnet AC servo motor and drive system ea Hannover trade fair ka 1978, sena se tšoaea hore moloko ona o mocha oa theknoloji ea AC servo o kene molemong oa tšebetso. Bohareng le bofelong ba lilemo tsa bo-1980, k'hamphani ka 'ngoe e ne e e-na le letoto le felletseng la lihlahisoa. Mmaraka oa servo kaofela o fetohela ho litsamaiso tsa AC. Boholo ba lits'ebetso tsa motlakase tse sebetsang hantle haholo li sebelisa enjene e sa feleng ea AC servo motor, 'me mokhanni oa taolo o sebelisa sistimi e felletseng ea dijithale ka boemo bo potlakileng le bo nepahetseng. Ho na le bahlahisi ba tloaelehileng joalo ka Siemens,Kollmorgen, Panasonic,Yaskawa, joalo-joalo.
Ka lebaka la ts'ebetso e nepahetseng ea enjene ea servo, e na le tlhoko e thata mabapi le ho nepahala ha ts'ebetso le ts'ebetso e phahameng, e itšetlehileng haholo ka boleng ba limatlase tsa Neodymium bakeng sa li-motor tsa servo. Ka lebaka la mefuta e mengata e fapaneng ea matla a khoheli, Neodymium makenete e etsa hore li-motor tsa servo li khonehe ka boima bo tlase le boholo bo nyane ha bo bapisoa le lisebelisoa tsa khale tsa makenete, joalo ka Ferrite, Alnico kapa SmCo magnets.
Bakeng sa limatlase tsa servo motor, hajoale Horizon Magnetics e hlahisa li-serial tsa limaraka tse holimo tsa limatlase tsa Neodymium, joalo ka H, SH, UH, EH le AH tse nang le litšobotsi tse tharo tse latelang:
1.High intrinsic coercivity Hcj: e phahameng ho >35kOe (>2785 kA/m) e eketsang kganyetso ya magnetizing demagnetizing ebe servo motor working stability
2.Li-coefficients tse tlase tsa mocheso tse fetolehang: tlase ho α(Br)< -0.1%/ºC le β(Hcj)< -0.5%/ºC e eketsang botsitso ba mocheso oa makenete le ho netefatsa hore li-motor tsa servo li sebetsa ka botsitso bo phahameng.
3.Tahlehelo e tlase ea boima ba 'mele: tlase ho 2 ~ 5mg/cm2 maemong a tlhahlobo ea HAST: 130ºC, 95% RH, 2.7 ATM, matsatsi a 20 a eketsang ho hanyetsa ho bola ha makenete ho lelefatsa nako ea bophelo ea li-motors tsa servo.
Ka lebaka la boiphihlelo ba rona bo ruileng ba ho fana ka baetsi ba likoloi tsa servo ka limatlase, Horizon Magnetics e utloisisa hore makenete ea servo motor e hloka liteko tse felletseng ho netefatsa boleng ba eona bo thata, joalo ka.maqhubu a demagnetizationka mocheso o phahameng ho bona ts'ebetso e tsitsitseng ea ts'ebetso, PCT & SST ho ithuta boleng ba likarolo tsa ho roala, HAST ho fumana tahlehelo ea boima ba 'mele, ho futhumatsa ka mocheso o phahameng ho ithuta tekanyo ea tahlehelo e ke keng ea qojoa, ho kheloha ha matla a khoheli ho fokotsa motlakase oa jitter, joalo-joalo.
