Ha ho na tabaMochine oa router oa 3d atc cnc, Mochini oa ho itšeha oa CO2 laserkapaMochini oa ho itšeha oa SS CS laserjoalo-joalo Motor ke e 'ngoe ea likarolo tsa motheo le tsa bohlokoa ka ho fetisisa.Enjene le mokhanni le tsona ke tsona tse4 × 8 ft cnc routertsamaiso e tsamaeang.Enjene le mokhanni ke ntho ea bohlokoa bakeng sa ts'ebetso ea ts'ebetso le ho nepahala ha mochini.E khethehileng bakeng sa ho sebetsa ka mokhoa o nepahetseng.Hape ho na le lintlha tse ling tse ngata tsa bohlokoa tse amang ho nepahala ha mochine.Empa qetellong, e hlokomeloa ka ho laola motsamao oa motlakase le kamohelo ea pontšo.

 

Ho na le mefuta e 'meli ea li-motor: Servo motor le step motor.Lefatšeng, ho na le bahlahisi ba bangata ba servo motor le bahlahisi ba bangata ba li-step motor.Tekai khetha feela lebitso le tsebahalang lefatšeng ka bophara.Bakeng sa motlakase oa servo, kamehla re khetha France Shield, Japanese Yaskawa, Taiwan Delta le Syntec joalo-joalo. Mohato oa motlakase re sebelisa Leadshine, 34MA, 450B kapa 450C.Phapang ea motor step le servo motor ke efe?

 

Ts'ebetso e fapaneng ea lipapali: Haeba lebelo la ho qala ha enjene e hatang le phahame haholo kapa mojaro o le moholo haholo, ho bonolo ho lahleheloa ke mehato kapa ho emisa.Ha lebelo le phahame haholo, ho bonolo ho baka overshoot.Ka hona, e le ho netefatsa ho nepahala ha taolo ea eona, bothata ba ho potlakisa le ho theoha bo lokela ho sebetsoa hantle.

 

Sistimi ea AC servo drive ke taolo ea loop e koetsoeng, koloi e ka etsisa ka kotloloho lets'oao la maikutlo la encoder ea enjine, 'me loop ea boemo ba kahare le loop ea lebelo lia thehoa.Ka kakaretso, ts'ebetso ea ho lahleheloa ke mohato kapa ho fetella ha mochini o ntseng o tsoela pele ho ke ke ha etsahala, mme ts'ebetso ea taolo e ka tšeptjoa haholoanyane.

 

Melemo ea li-motors tsa servo ho feta li-stepper motors ke tse latelang

 

Matšeliso: Mocheso le lerata li fokotsehile haholo.

 

Lebelo: ts'ebetso e ntle ea lebelo le phahameng, lebelo le lekantsoeng ka kakaretso le ka fihla ho 20003000 rpm;

 

Ho nepahala: taolo e koetsoeng ea boemo, lebelo le torque e phethahala;bothata ba stepper motor ho tsoa-mohato bo hlōtsoe;

 

Nako: Nako ea karabelo e matla ea ho potlakisa koloi le ho theola lebelo e khuts'oane, ka kakaretso ka har'a mashome a milliseconds;

 

E tsitsitseng: Ts'ebetso ea lebelo le tlaase e tsitsitse, 'me ts'ebetso ea ts'ebetso ea ho hatakela e ts'oanang le koloi e tsamaeang e ke ke ea etsahala ha ts'ebetso e tlaase e etsoa.E sebetsa liketsahalong tse nang le litlhoko tsa karabelo ea lebelo le holimo;

 

Ho ikamahanya le maemo: Bokhoni bo matla ba ho thibela boima ba 'mele, bo khona ho mamella meroalo ka makhetlo a mararo ho feta torque e lekantsoeng, haholo-holo e loketseng liketsahalo tse nang le ho fetoha ha meroalo hang-hang le litlhoko tsa ho qala ka potlako;

 

Servo motor

 

Servo ke taolo ea loop e koetsoeng, stepper ke taolo e bulehileng, ena ke phapang ea mantlha.Ka ho khetheha, servo motor e koetsoe-loop control (e phethiloeng ke maikutlo a encoder, joalo-joalo), ke hore, lebelo la motlakase le tla lekanyetsoa ka nako ea sebele;Enjene ea stepper ke taolo e bulehileng ea loop, kenya pulse, motor stepper e tla fetola angle e tsitsitseng, empa Velocity ha e lekanngoe.

 

Torque e qalang ea servo motor e kholo haholo, ke hore, ho qala ho potlakile.Lebelo le lekantsoeng le ka finyelloa ka nako e khutšoanyane haholo.E loketse ho qala le ho emisa khafetsa mme ho na le tlhoko ea ho qala torque.Ka nako e ts'oanang, matla a motlakase oa servo a ka ba kholo haholo, 'me a sebelisoa haholo tlhahiso.Ho qala ha mochini oa stepper ho batla ho le butle, 'me e tlameha ho feta mokhoeng oa maqhubu ho tloha tlase ho ea holimo.Li-motor tsa Stepper ka kakaretso ha li na bokhoni ba ho jara, ha li-motor tsa servo li tletse haholo.
