Servo motor e ts'oana le motor stepper ts'ebetsong le sebopeho, empa ts'ebetso ea servo motor e fapane haholo. Phapang ke efe ka ho khetheha? Phapang ke efe lipakeng tsa servo motor le step motor ha ho sebelisoa lisebelisoa tsa mochini o nepahetseng?
Pele, litšobotsi tse tlase tsa maqhubu a servo motor le stepper motor li fapane.
Stepper motor e tloaetse ho thothomela ho maqhubu a tlase ka lebelo le tlase. Molao-motheo o sebetsang oa motor motor oa mohato o khetholla hore ketsahalo e tlase ea thothomelo e tlase ha e rate ts'ebetso ea mochini. Bakhanni ba bangata ba mehato ka bo bona ba bala lintlha tsa bona tsa thothomelo ho fetola algorithm ea taolo ho thibela ho sisinyeha ha bona.
Ac servo motor e sebetsa hantle haholo, leha e le ka lebelo le tlase e ke ke ea hlaha e le ntho e sisinyehang. Sisteme ea Ac servo e na le ts'ebetso ea khatello ea molumo, e ka etsetsang khaello ea metjhine, mme e na le ts'ebetso ea khafetsa ea analytic (FFT) kahare ho sistimi, e ka bonang ntlha ea molumo oa mechini le ho tsamaisa ntlafatso ea sistimi.
Taba ea bobeli, ts'ebetso ea servo motor le stepper motor e fapane.
Taolo ea koloi e kenang e bulehile ka bongata, maqhubu a qalang a phahame haholo kapa mojaro o moholo haholo, mme ts'ebetso ea overshoot kapa overshoot e bonolo ho hlaha ha lebelo le le holimo haholo, ka hona ho netefatsa taolo ea lona e nepahetseng, mathata a ho phahama le ho theoha ha lebelo a lokela ho sebetsoa hantle. Sistimi ea drive ea AC servo e koetsoe ka taolo ea loop. Mokhanni a ka latsoa ka kotloloho letšoao la maikutlo la encoder ea makoloi. Lesale la boemo le lesale la lebelo li thehiloe kahare. Ka kakaretso, ha ho na tahlehelo ea mohato kapa koloi e fetang, mme ts'ebetso ea taolo e ts'epahala.
Taba ea boraro, litšobotsi tsa motsotsoana oa servo motor le stepper li fapane.
Phallo ea motlakase ea stepper e fokotseha ka keketseho ea lebelo, 'me e tla fokotseha haholo ka lebelo le phahameng, ka hona lebelo le phahameng la ts'ebetso ea motor stepper hangata ke 300 ~ 600 RPM .. Phallo ea motlakase oa stepper e tla fokotseha ka lebelo le phahameng Mochini oa AC servo o hlahisa torque khafetsa, ke hore, ka lebelo la eona le lekantsoeng (ka kakaretso 2000 RPM kapa 3000 RPM), e ka hlahisa torque e lekantsoeng le tlhahiso ea motlakase e sa feleng ka lebelo le lekantsoeng.
Ntlha ea bone, tšebetso ea karabelo ea lebelo la makoloi a tsamaeang ka maoto e fapane.
Koloi e tsamaeang ka maoto e nka li-millisecond tse 200 ~ 400 ho potlakisa ho tloha phomolong ho ea lebelo la ho sebetsa, hangata liphetohelo tse makholo ka motsotso. Ts'ebetso ea matsapa ea sistimi ea AC servo e ntle. Ho nka mohlala oa Mingzhi 400 W AC servo motor, ho nka li-millisecond tse 'maloa feela ho potlakisa ho tloha static ho isa lebelo la eona la 3000 RPM le ka sebelisoang maemong a taolo le hlokang ho qala le ho emisa kapele.
Maemong a mang a boima haholo, li-servo motors tse nang le ts'ebetso e phahameng haholo ho feta li-motor stepper li tlameha ho sebelisoa. Leha China e na le karolo ea liindasteri e felletseng ho fetisisa lefats'eng, boholo ba bona ba lebaleng la "sebete le mahala", mme ho ntse ho na le lekhalo le leholo pokellong ea lihlahisoa tsa maemo a holimo.
Ea bohlano, servo motor le stepper motor control nepe e fapane.
Karolo ea mehato ea likarolo tse peli tsa lebasetere le hatang ke 1.8,0.9, 'me ea mekhahlelo e mehlano ea enjene e nyolohang ke 0.72,0.36. Leha ho le joalo, ho nepahala ha taolo ea AC servo motor ho netefalitsoe ke encoder ea rotary pheletsong e ka morao ea shaft motor. Bakeng sa dilenaneo tse nang le encoder e nyane ea 17,
