Yuav Ua Li Cas Ntsuam Xyuas Stepper Tsav nrog Multimeter (Cov Lus Qhia)
Txheem
Stepper lub cev muaj zog yog DC lub cev muaj zog uas tuaj yeem "tswj" los ntawm microcontroller, thiab nws cov khoom tseem ceeb yog rotator thiab stator. Lawv yog siv nyob rau hauv disk drives, floppy disks, computer printers, gaming machines, duab scanners, CNC machines, CDs, 3D printers, thiab ntau lwm yam khoom zoo sib xws.
Qee lub sij hawm stepper motors raug puas tsuaj, ua rau txoj kev hluav taws xob txuas ntxiv mus. Koj lub tshuab luam ntawv 3D, lossis lwm lub tshuab siv cov motors no, yuav tsis khiav yam tsis muaj kev txuas ntxiv. Yog li nws yog ib qho tseem ceeb los xyuas seb koj lub tshuab stepper puas muaj kev txuas ntxiv.
Feem ntau, koj yuav xav tau ib lub multimeter los ntsuas kev ncaj ncees ntawm koj lub cev muaj zog stepper. Pib los ntawm kev teeb tsa koj lub multimeter. Tig lub pob qhov rooj rau qhov chaw tiv thaiv thiab txuas cov multimeter ua rau cov chaw nres nkoj tsim nyog, piv txwv li cov hlau lead dub mus rau ntu COM thiab cov hlau lead liab mus rau qhov chaw nres nkoj nrog tsab ntawv "V" nyob ib sab ntawm nws. Kho lub multimeter los ntawm kev sib txuas cov kev sojntsuam ua ke. Txheeb xyuas cov xov hlau lossis cov neeg sib cuag ntawm tus stepper. Ua tib zoo saib cov lus qhia ntawm cov zaub.
Feem ntau, yog tias tus neeg xyuas pib muaj txoj hauv kev txuas mus ntxiv, kev nyeem ntawv yuav nyob nruab nrab ntawm 0.0 thiab 1.0 ohms. Koj yuav tsum tau yuav tus tshiab stepper rotator yog tias koj tau txais kev nyeem ntau dua 1.0 ohms. Qhov no txhais tau hais tias qhov tsis kam rau hluav taws xob tam sim no siab dhau lawm.
Yuav ua li cas koj yuav tsum tau mus xyuas lub stepper rotator nrog ib tug multimeter
Koj yuav xav tau cov cuab yeej hauv qab no:
- Stepper rotator
- 3D tshuab luam ntawv
- Cov kauj ruam cable uas mus rau lub tshuab luam ntawv lub motherboard - lub coax cable yuav tsum muaj 4 tus pins.
- Plaub nyob rau hauv cov ntaub ntawv ntawm stepper motors nrog nyob ntawm tej
- Cov multimeter
- Multimeter sojntsuam
- Daim kab xev nplaum
Kev teeb tsa multimeter
Pib los ntawm kev xaiv Ohm nyob rau hauv lub multimeter siv lub qhov rooj xaiv. Xyuas kom koj muaj 20 ohms raws li qhov qis tshaj. Qhov no yog vim qhov tsis kam ntawm feem ntau stepper lub cev muaj zog coils tsawg dua 20 ohms. (1)
Txuas kev xeem ua rau cov chaw nres nkoj multimeter.. Yog tias qhov kev sojntsuam tsis txuas nrog cov chaw nres nkoj uas tsim nyog, txuas rau lawv raws li hauv qab no: ntxig lub xov tooj liab rau hauv qhov chaw nres nkoj nrog "V" nyob ib sab ntawm nws, thiab cov kev sojntsuam dub rau hauv qhov chaw nres nkoj sau tias "COM". Tom qab txuas cov probes, npaj mus kho lawv.
Kev hloov kho Multimeter yuav qhia rau koj yog tias lub multimeter ua haujlwm lossis tsis ua haujlwm. Ib tug luv luv beep txhais tau hais tias lub multimeter nyob rau hauv zoo mob. Cia li txuas cov probes ua ke thiab mloog lub beep. Yog tias nws tsis beep, hloov nws los yog coj mus rau tus kws kho mob tshwj xeeb.
Kev sim cov xov hlau uas yog ib feem ntawm tib lub kauj
Tom qab koj tau teeb tsa koj lub multimeter, pib sim lub stepper lub cev muaj zog. Txhawm rau kuaj cov xov hlau uas yog ib feem ntawm ib lub kauj, txuas cov xaim liab los ntawm cov kauj ruam mus rau qhov kev sojntsuam liab.
Tom qab ntawd muab cov hlau daj thiab txuas mus rau qhov kev sojntsuam dub.
Hauv qhov no, lub multimeter yuav tsis beep. Qhov no yog vim qhov sib xyaw xim daj / liab tsis xa mus rau tib lub kauj.
Yog li ntawd, thaum tuav lub xov tooj liab ntawm lub xov tooj liab, tso cov hlau daj thiab txuas cov hlau dub mus rau qhov kev sojntsuam dub. Koj lub multimeter yuav beep tsis tu ncua kom txog rau thaum koj tawg lossis qhib qhov hloov pauv los ntawm kev txiav tawm cov multimeter ua. Lub beep txhais tau hais tias cov xov hlau dub thiab liab nyob ntawm tib lub kauj.
Kos cov xov hlau ntawm ib lub kauj, i.e. dub thiab liab, txuas lawv nrog daim kab xev. Tam sim no mus tom ntej thiab txuas cov kev xeem liab coj mus rau cov xaim ntsuab, thiab tom qab ntawd kaw qhov hloov pauv los ntawm kev txuas cov xaim daj rau cov hlau kuaj dub.
Lub multimeter yuav beep. Kuj kos ob lub xov hlau no nrog daim kab xev.
Tiv tauj mus kuaj nyob rau hauv rooj plaub ntawm tus pin hlau
Zoo, yog tias koj tus stepper siv lub coaxial cable, koj yuav tsum tau xyuas cov pins ntawm cable. Feem ntau muaj 4 tus pins - ib yam li 4 xov hlau nyob rau hauv ib tug wired stepper rotator.
Thov ua raws li daim duab hauv qab no txhawm rau ua qhov kev xeem txuas ntxiv rau hom stepper motor:
- Txuas cov kev xeem liab coj mus rau thawj tus pin ntawm lub cable thiab tom qab ntawd lwm qhov kev sim ua rau tus pin tom ntej. Tsis muaj polarity, yog li nws tsis muaj teeb meem qhov kev sojntsuam mus qhov twg. Nco ntsoov tus nqi ohm ntawm qhov screen.
- Khaws qhov kev sojntsuam tas li ntawm thawj tus pas nrig, txav mus rau lwm qhov kev sojntsuam hla tus pas nrig, nco ntsoov nyeem txhua zaus. Koj yuav pom tias multimeter tsis beep thiab tsis sau npe nyeem ntawv. Yog tias muaj, koj tus stepper yuav tsum tau kho.
- Nqa koj cov kev soj ntsuam thiab muab lawv rau 3rd thiab 4th sensors, them sai sai rau kev nyeem ntawv. Koj tsuas yog yuav tsum tau txais kev nyeem ntawv tsis kam ntawm ob tus pins hauv koob.
- Koj tuaj yeem mus tom ntej thiab tshawb xyuas qhov tseem ceeb ntawm kev tiv thaiv ntawm lwm cov steppers. Sib piv cov nqi.
Summing txog
Thaum kuaj xyuas qhov kev tiv thaiv ntawm lwm cov steppers, tsis txhob sib tov cov cables. Cov kauj ruam sib txawv muaj cov kab hluav taws xob sib txawv, uas tuaj yeem ua rau lwm cov kab tsis sib xws. Txwv tsis pub koj tuaj yeem tshawb xyuas cov xaim hluav taws xob, yog tias 2 cov kauj ruam muaj tib txoj kev sib txuas, ces koj siv cov kab sib hloov. (2)
