Mokhoa oa ho lekola koloi ea Stepper ka Multimeter (Tataiso)

Enjene ea stepper ke enjene ea DC e ka "laoloang" ke microcontroller, 'me likarolo tsa eona tsa mantlha ke rotator le stator. Li sebelisoa ho li-disk drive, li-floppy disks, liprinta tsa khomphutha, mechini ea lipapali, li-scanner tsa litšoantšo, mechini ea CNC, li-CD, liprinta tsa 3D, le lisebelisoa tse ling tse ngata tse tšoanang.

Ka linako tse ling li-motors tsa stepper lia senyeha, e leng ho bakang hore tsela e tsoelang pele ea motlakase e robehe. Mochine oa hau oa khatiso oa 3D, kapa mochini ofe kapa ofe o sebelisang li-motor tsena, o ke ke oa sebetsa ntle le ho tsoela pele. Kahoo ho bohlokoa ho lekola hore na mochini oa stepper o na le ts'ebetso.

Ka tloaelo, o tla hloka multimeter ho leka botšepehi ba mochini oa hau oa stepper. Qala ka ho theha multimeter ea hau. Fetolela sekheo sa mokhethoa ho ea boemong ba ho hanyetsa 'me u kopanye li-multimeter tse lebisang likoung tse loketseng, ke hore moetapele o motšo ho ea karolong ea COM le mofubelu o mofubelu ho ea koung e nang le lengolo "V" haufi le eona. Fetola multimeter ka ho hokahanya li-probes hammoho. Sheba lithapo kapa mabitso a stepper. Ela hloko matšoao a hlahang skrineng.

Ka tloaelo, haeba mokhanni a e-na le tsela e tsoelang pele ea motlakase, ho bala ho tla ba pakeng tsa 0.0 le 1.0 ohms. U tla hloka ho reka rotator e ncha haeba u bala ho feta 1.0 ohms. Sena se bolela hore khanyetso ea motlakase e phahame haholo.

Seo u se hlokang ho hlahloba rotator ea stepper ka multimeter

U tla hloka lisebelisoa tse latelang:

• Rotator ea mohato
• Mohatisi oa 3D
• Mohala oa mohato o eang lebokoseng la "motherboard" - mohala oa coax o tlameha ho ba le lithapo tse 4.
• Lithapo tse 'nè tabeng ea li-motors tsa stepper tse nang le lithapo
• Digital multimeter
• Multimeter probes
• Theipi e khomarelang

Litlhophiso tsa Multimeter

Qala ka ho khetha Ohm ho multimeter ho sebelisa konopo ea khetho. Etsa bonnete ba hore o na le li-ohm tse 20 joalo ka tse tlase. Sena ke hobane khanyetso ea li-coil tse ngata tsa stepper motor e ka tlase ho 20 ohms. (1)

Hokela teko ho isa likoung tsa multimeter.. Haeba li-probes li sa kopane le likoung tse loketseng, li kopanye ka tsela e latelang: kenya probe e khubelu ka har'a koung e nang le "V" haufi le eona, 'me phuputso e ntšo ka har'a koung e ngotsoeng "COM". Ka mor'a ho kopanya li-probes, tsoela pele ho li lokisa.

Multimeter phetoho e tla u bolella hore na multimeter e sebetsa kapa che. Beep e khuts'oane e bolela hore multimeter e maemong a matle. Kopanya feela li-probes 'me u mamele beep. Haeba e sa lla, e khutlise kapa u e ise ho setsebi bakeng sa ho e lokisa.

Lithapo tsa teko tseo e leng karolo ea khoele e tšoanang

Kamora ho theha multimeter ea hau, qala ho lekola mochini oa stepper. Ho leka lithapo tseo e leng karolo ea khoele e le 'ngoe, hokela terata e khubelu ho tloha ho stepper ho ea ho probe e khubelu.

Ebe u nka terata e mosehla 'me ue kopanye le probe e ntšo.

Tabeng ena, multimeter e ke ke ea lla. Sena se bakoa ke hore terata e mosehla / e khubelu ha e bolele khoele e le 'ngoe.

Kahoo, ha u ntse u tšoere terata e khubelu holim'a probe e khubelu, lokolla mohala o mosehla 'me u kopanye terata e ntšo ho probe e ntšo. Multimeter ea hau e tla lla khafetsa ho fihlela o roba kapa o bula switch ka ho hakolla li-lead tsa multimeter. Beep e bolela hore lithapo tse ntšo le tse khubelu li holim'a khoele e le 'ngoe.

Tšoaea lithapo tsa coil e le 'ngoe, i.e. e ntšo le e khubelu, e li kopanya ka tepi. Joale tsoela pele 'me u kopanye tataiso ea teko e khubelu ho terata e tala, ebe u koala sesebelisoa ka ho hokahanya terata e mosehla ho ea pele ea teko e ntšo.

Multimeter e tla lla. Hape tšoaea lithapo tsena tse peli ka theipi.

Teko ea mabitso haeba ho na le mohala oa phini

Le ha ho le joalo, haeba stepper sa hau se sebelisa thapo ea coaxial, u tla hloka ho hlahloba lithapo tsa thapo. Hangata ho na le lithapo tse 4 - joalo ka lithapo tse 4 ka har'a rotator e nang le terata.

Ka kopo latela setšoantšo se ka tlase ho etsa tlhahlobo ea ho tsoelapele bakeng sa mofuta ona oa li-stepper motor:

1. Hokela tlhahlobo e khubelu ho phini ea pele ea thapo ebe tlhahlobo e 'ngoe e lebisa pineng e latelang. Ha ho na polarity, kahoo ha ho na taba hore na tlhahlobo e ea kae. Ela hloko boleng ba ohm skrineng sa ponts'o.
2. Ho boloka probe kamehla holim'a molamu oa pele, tsamaisa karolo e 'ngoe ho pholletsa le lithupa tse setseng, u hlokomele ho bala nako le nako. U tla fumana hore multimeter ha e bipe ebile ha e ngolise ho baloa. Haeba ho joalo, stepper sa hau se hloka ho lokisoa.
3. Nka lisebelisoa tsa hau 'me u li kopanye ho 3^rd le 4^th li-sensor, ela hloko ho bala. U lokela ho fumana feela lipalo tsa khanyetso holim'a lithakhisa tse peli tse latellanang.
4. U ka tsoela pele ho lekola boleng ba khanyetso ba li-steppers tse ling. Bapisa litekanyetso.

Ho akaretsa

Ha u hlahloba ho hanyetsa ha li-steppers tse ling, u se ke ua kopanya lithapo. Li-steppers tse fapaneng li na le litsamaiso tse fapaneng tsa wiring, tse ka senyang likhoele tse ling tse sa lumellaneng. Ho seng joalo, o ka hlahloba mohala, haeba li-steppers tse 2 li na le mekhoa e tšoanang ea lithapo, joale u sebelisa likhoele tse feto-fetohang. (2)
