Mokhanni o laola motlakase oa mekhahlelo e meraro ea U / V / W ho theha tšimo ea motlakase, 'me rotor e potoloha tlas'a ketso ea matla a khoheli.Ka nako e ts'oanang, encoder ea enjene e khutlisetsa lets'oao ho drive.Mokhanni o bapisa boleng ba maikutlo le boleng ba sepheo sa ho fetola lebelo la ho potoloha ha rotor. Ho nepahala ha motlakase oa servo ho itšetlehile ka ho nepahala (palo ea mela) ea encoder.E arotsoe ka DC le AC servo motors.Ntho ea eona e ka sehloohong ke hore ha motlakase oa pontšo e le zero, ha ho na mokhoa oa ho potoloha, 'me lebelo le fokotseha ka ho lekana le ho eketseha ha torque.Utloisisa sebopeho sa mantlha sa koloi ea servo, tseba molao-motheo oa eona oa ts'ebetso, litšoaneleho tsa ts'ebetso le litšoaneleho, le linako tsa ts'ebeliso, e le hore u ka e khetha le ho e sebelisa ka nepo.Litšobotsi tsa molao-motheo oa ho sebetsa oa servo motor ke life?
1. Servo motor ke eng?
Servo motors, tse tsejoang hape e le li-actuator motors, ke li-actuator tsamaisong ea taolo e fetolelang matšoao a motlakase hore e be li-angles kapa lebelo ho shaft ho khanna ntho ea taolo.Servo motor, eo hape e tsejoang e le motor motor, ke karolo ea tsamaiso tsamaisong ea othomathike ea taolo e fetolang lets'oao la motlakase le amohetsoeng hore e be phallo ea li-angular kapa phallo ea lebelo la koloi ho shaft ea motor.
E arotsoe ka DC le AC servo motors.Ntho ea eona e ka sehloohong ke hore ha motlakase oa pontšo e le zero, ha ho na mokhoa oa ho potoloha, 'me lebelo le fokotseha ka ho lekana le ho eketseha ha torque.
2. Boholo ba litšobotsi tsa servo motor
Ha ho na le tlhahiso ea pontšo ea taolo, servo motor e potoloha;haeba ho se na tlhahiso ea lets'oao la taolo, e tla emisa ho potoloha.Lebelo le tataiso ea koloi ea servo li ka fetoloa ka ho fetola boholo le karolo (kapa polarity) ea motlakase oa taolo.Ho tloha lilemong tsa bo-1980, ka nts'etsopele ea lipotoloho tse kopantsoeng, theknoloji ea elektronike ea matla le theknoloji ea taolo ea lebelo la AC, theknoloji e sa feleng ea magnet AC servo drive e entse tsoelo-pele e kholo.Baetsi ba makoloi ba tummeng linaheng tse fapaneng ba hlahisitse letoto la bona la li-AC servo motors le li-servo drives, 'me ba lula ba ntlafatsa le ho nchafatsa.
Sistimi ea AC servo e fetohile tataiso e ka sehloohong ea nts'etsopele ea sistimi ea sejoale-joale ea ts'ebetso e phahameng, e etsang hore sistimi ea pele ea servo ea DC e tobane le koluoa ea ho felisoa.Kamora lilemo tsa bo-1990, litsamaiso tsa khoebo tsa AC servo lefatšeng ka bophara li ne li tsamaisoa ke li-motor tsa sine wave tse laoloang ka botlalo.Nts'etsopele ea li-drive tsa servo tsa AC tšimong ea phetisetso e ntse e fetoha ha letsatsi le letsatsi le feta.
3. Ha ho bapisoa le li-motor tse tloaelehileng, li-motors tsa servo li na le litšobotsi tse latelang
(1) Lebelo la taolo ea lebelo le pharaletseng.Ha matla a taolo a fetoha, lebelo la enjene ea servo le ka lula le fetoloa maemong a fapaneng.
(2) Rotor inertia e nyenyane, kahoo e ka qala le ho emisa kapele.
(3) Matla a ho laola a manyenyane, matla a mangata a matla a matla, 'me ho tšepahala ho molemo.
4. Tšebeliso e tloaelehileng ea servo motor tsamaisong ea ho laola ka mokhoa o itekanetseng

Melao-motheo ea ts'ebetso ea li-motors tsa servo ke efe?Ho akaretsa, lits'ebetso tsa AC servo li phahame ho feta li-motor tsa stepper ka mekhoa e mengata.Leha ho le joalo, maemong a mang a sa batleng haholo, li-motors tsa stepper hangata li sebelisoa e le li-motors tsa actuator.Ka hona, ts'ebetsong ea moralo oa sistimi ea taolo, hoa hlokahala ho nahanisisa ka botlalo litlhoko tsa taolo, litšenyehelo le lintlha tse ling ho khetha koloi e nepahetseng ea taolo.
