1.Ke engstepper motor?
Li-motors tsa Stepper li tsamaea ka tsela e fapaneng ho feta lienjineri tse ling. DC stepper motors sebelisa discontinuous movement. Ho na le lihlopha tse ngata tsa li-coil 'meleng ea tsona, tse bitsoang "mehato", tse ka fetoloang ka ho kenya tšebetsong mohato o mong le o mong ka tatellano. Mohato o le mong ka nako.
Ka ho laola mochini oa stepper ka molaoli / khomphutha, o ka emisa ka nepo ka lebelo le nepahetseng. Ka lebaka la molemo ona, li-motors tsa stepper hangata li sebelisoa haholo lisebelisoa tse hlokang ho tsamaea hantle.
Li-motors tsa Stepper li na le boholo bo fapaneng, libopeho le meralo. Sengoliloeng sena se tla hlalosa ka ho hlaka mokhoa oa ho khetha mochini oa stepper ho latela litlhoko tsa hau.
2. Melemo eali-motors tsa stepper?
A. Boemo- Hobane motsamao oa li-motors tsa stepper o nepahetse ebile o pheta-pheta, o ka sebelisoa mefuteng e fapaneng ea lihlahisoa tse laoloang hantle, joalo ka khatiso ea 3D, CNC, sethala sa khamera, joalo-joalo, li-drive tse ling tse thata le tsona li sebelisa step Motor ho beha hlooho e baloang.
B. Ho laola lebelo- mehato e nepahetseng e boetse e bolela hore o ka khona ho laola lebelo la ho potoloha ka nepo, e loketseng ho etsa liketso tse nepahetseng kapa taolo ea liroboto.
C. Lebelo le tlase le torque e phahameng- Ka kakaretso, li-motor tsa DC li na le torque e tlase ka lebelo le tlase. Empa li-motor tsa stepper li na le torque e phahameng ka lebelo le tlase, ka hona ke khetho e ntle bakeng sa lits'ebetso tse nepahetseng haholo.
3. Mefokolo eastepper motor :
A. Ho se sebetse hantle- Ho fapana le li-motors tsa DC, ts'ebeliso ea li-motors tsa stepper ha e amane haholo le mojaro. Ha ba sa etse mosebetsi, ho ntse ho e-na le hona joale, kahoo hangata ba na le mathata a ho futhumala ho feteletseng, 'me ts'ebetso e tlase haholo.
B. Torque ka lebelo le phahameng- hangata torque ea stepper motor ka lebelo le phahameng e tlase ho feta lebelo le tlase, li-motor tse ling li ntse li ka fihlela ts'ebetso e ntle ka lebelo le holimo, empa sena se hloka koloi e ntle ho fihlela phello ena.
C. Ha e khone ho beha leihlo- li-motors tse tloaelehileng tsa stepper ha li khone ho fana ka maikutlo / ho lemoha boemo ba koloi ea hona joale, re e bitsa "loop e bulehileng", haeba u hloka taolo ea "loop e koetsoeng", u lokela ho kenya mochine oa ho kenya mochine le mokhanni, e le hore u ka shebella / laola ho potoloha ho nepahetseng ha koloi ka nako leha e le efe, empa litšenyehelo li phahame haholo 'me ha li loketse lihlahisoa tse tloaelehileng.
Mohato oa Motor Phase
4. Sehlopha sa ho hata:
Ho na le mefuta e mengata ea li-motors tsa stepper, tse loketseng maemo a fapaneng.
Leha ho le joalo, tlas'a maemo a tloaelehileng, li-motors tsa PM le hybrid stepper motors hangata li sebelisoa ntle le ho nahana ka li-motors tsa poraefete.
5. Boholo ba koloi:
Ntho ea pele eo u lokelang ho e ela hloko ha u khetha enjene ke boholo ba enjene. Li-motors tsa Stepper li tloha ho 4mm miniature motors (tse sebelisoang ho laola motsamao oa lik'hamera ho li-smartphone) ho ea ho li-behemoth tse kang NEMA 57.
Enjene e na le torque e sebetsang, torque ena e etsa qeto ea hore na e ka fihlela tlhoko ea hau ea matla a enjene.
Mohlala: NEMA17 hangata e sebelisoa ho liprinta tsa 3D le lisebelisoa tse nyane tsa CNC, 'me li-motor tse kholo tsa NEMA li sebelisoa tlhahiso ea indasteri.
NEMA17 mona e bua ka bophara ba kantle ba enjene ke lisenthimithara tse 17, e leng boholo ba sistimi ea inch, e leng 43cm ha e fetoleloa ho lisentimitara.
China, ka kakaretso re sebelisa lisentimitara le limilimithara ho metha litekanyo, eseng li-inchi.
6. Palo ea mehato ea motlakase:
Palo ea mehato ka phetoho ea motlakase e lekanya qeto ea eona le ho nepahala. Li-motors tsa Stepper li na le mehato ho tloha ho 4 ho isa ho 400 ka phetoho e 'ngoe. Hangata ho sebelisoa mehato e 24, 48 le 200.
Ho nepahala hangata ho hlalosoa e le tekanyo ea mohato ka mong. Ka mohlala, mohato oa motlakase oa mehato e 48 ke likhato tse 7,5.
Leha ho le joalo, litšitiso tsa ho nepahala ho phahameng ke lebelo le torque. Ka nako e ts'oanang, lebelo la li-motor tse nepahetseng haholo le tlase.
7. Lebokose la lisebelisoa:
Tsela e 'ngoe ea ho ntlafatsa ho nepahala le torque ke ho sebelisa lebokose la gear.
Mohlala, lebokose la li-gearbox tsa 32: 1 le ka fetola enjene ea mehato e 8 ho enjene e nepahetseng ea mehato e 256, ha e ntse e eketsa torque ka makhetlo a 8.
Empa lebelo la tlhahiso le tla fokotsoa ka tsela e tšoanang ho karolo ea borobeli ea ea pele.
Enjene e nyane le eona e ka fihlela phello ea torque e phahameng ka lebokose la gear la phokotso.
8. Shaft:
Ntho ea ho qetela eo u hlokang ho e nahana ke mokhoa oa ho ts'oana le shaft ea koloi le mokhoa oa ho ts'oana le sistimi ea hau ea koloi.
Mefuta ea li-shafts ke:
Round shaft / D shaft: Mofuta ona oa shaft ke oona o tloaelehileng ka ho fetisisa oa lihlahisoa, o sebelisetsoang ho hokahanya li-pulleys, li-gear sets, joalo-joalo D shaft e loketse haholo bakeng sa torque e phahameng ho thibela ho thella.
Gear shaft: The shaft e hlahisoang ke li-motor tse ling ke gear, e sebelisetsoang ho tsamaisana le sistimi e itseng ea lisebelisoa
Screw shaft: Enjene e nang le screw shaft e sebelisoa ho aha mochini o sebetsang, 'me selaete se ka eketsoa ho fihlela taolo ea mola.
Ka kopo, ikutloe u lokolohile ho ikopanya le rona haeba u na le thahasello ho efe kapa efe ea li-motor tsa rona.
