Dab tsi yuav tsum tau them sai sai rau thaum xaiv lub tshuab brushless stepper

Thaum xaiv lub cev muaj zog stepper, thawj yam uas yuav tsum tau saib yog nws hom. Raws li tau hais ua ntej, hom lub cev muaj zog no tuaj yeem muab faib ua ntau hom. Qhov twg xaiv? Txhua hom muaj qhov ua haujlwm zoo ib yam, tab sis nws yuav muaj qee qhov sib txawv ntawm cov yam ntxwv ntawm kev ua haujlwm thiab kev ua haujlwm ntawm daim ntawv thov. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog los txiav txim siab seb lub cav twg yuav xaiv raws li qhov xav tau ntawm kev ua haujlwm sib txawv ntawm lub cev muaj zog. Uas yog hais, thawj kauj ruam ntawm kev xaiv yog los txiav txim seb hom. Qhov thib ob, thaum xaiv lub tshuab stepper, peb kuj yuav tsum tau saib qhov zoo. Qhov zoo ntawm lub cev muaj zog yog qhov teeb meem tseem ceeb, vim tias tsis hais hom twg, qhov zoo yog qhov teeb meem tseem ceeb. Yog tias qhov zoo tsis zoo, qhov kev xaiv ntawm lub tshuab tsim nyog yuav zoo ib yam. Tsis yog siv tau, qhov no yog qhov teeb meem uas xav tau kev saib xyuas.

Ib, xaiv tuav torque

Tuav torque tseem hu ua static torque, uas yog hais txog lub torque uas lub stator xauv lub rotor thaum lub stepper lub cev muaj zog tab sis tsis tig. Txij li thaum lub torque ntawm lub stepper lub cev muaj zog nyob rau hauv qis ceev yog ze rau lub tuav torque, thiab lub torque ntawm lub stepper lub cev muaj zog decays sai sai nrog rau qhov nce ntawm kev ceev, cov zis hwj chim kuj hloov nrog qhov nce ntawm ceev, yog li lub tuav torque yog ib qho kev ntsuas. ntawm stepping. Ib qho tseem ceeb tshaj plaws ntawm lub cev muaj zog load peev. Piv txwv li,-feem ntau hais txog 1N.m stepper lub cev muaj zog yam tsis tau piav qhia, nws tuaj yeem nkag siab tias lub zog tuav yog 1Nm.

Qhov thib ob, xaiv tus naj npawb ntawm theem

Ob-theem stepper lub cev muaj zog muaj tus nqi qis, lub kaum sab xis yog tsawg kawg yog 1.8 degrees, kev vibration ntawm qis ceev yog loj, thiab lub zog torque poob sai sai ntawm kev kub ceev. Nws yog qhov tsim nyog rau lub sijhawm siab ceev nrog cov kev xav tau qis rau qhov raug thiab ruaj khov; peb-theem stepper lub cev muaj zog kauj ruam deb Lub kaum sab xis yog tsawg kawg yog 1.2 degrees, qhov kev vibration yog me dua li ob-theem stepper lub cev muaj zog, thiab qhov kev ua haujlwm qis yog zoo dua li ob-theem stepper lub cev muaj zog. Qhov siab tshaj plaws ceev yog 30 mus rau 50% siab dua ob-theem stepper lub cev muaj zog. Nws yog qhov tsim nyog rau kev kub ceev thiab xav tau qhov tseeb thiab ruaj khov. Lub sijhawm siab dua; 5-theem stepping lub cev muaj zog lub kaum sab xis me dua, thiab nws qhov kev ua haujlwm qis qis zoo dua li 3-theem stepping lub cev muaj zog, tab sis tus nqi siab dua. Nws yog qhov tsim nyog rau lub sijhawm uas yuav tsum tau muaj qhov tseeb thiab kev ruaj ntseg hauv nruab nrab thiab qis qis.

Peb, xaiv stepper motor

Lub hauv paus ntsiab lus ntawm kev xaiv lub cev muaj zog ua ntej thiab tom qab ntawd tus tsav tsheb kauj vab yuav tsum ua raws. Ua ntej, cov yam ntxwv ntawm kev thauj khoom yuav tsum tau qhia meej, thiab tom qab ntawd los ntawm kev sib piv cov static torque thiab torque-frequency curves ntawm ntau hom stepping motors, stepping lub cev muaj zog uas zoo tshaj plaws cov yam ntxwv load yuav tsum pom; Thaum cov kev xav tau raug siab, nws yuav tsum tau Siv lub tshuab ua kom lub cev muaj zog kom lub cev muaj zog ua haujlwm hauv lub xeev nrog kev ua haujlwm siab tshaj plaws thiab lub suab qis tshaj; tsis txhob ua kom lub cev muaj zog ua haujlwm nyob rau hauv qhov chaw vibration, yog tias tsim nyog, hloov qhov voltage, tam sim no los yog nce damping txoj kev los daws qhov teeb meem; lub zog hluav taws xob voltage

Plaub, xaiv raws li kev siv ib puag ncig ntawm lub tshuab stepper

Qhov tshwj xeeb stepping lub cev muaj zog yog waterproof thiab roj-pov thawj, thiab yog siv nyob rau hauv qee lub sijhawm tshwj xeeb. Piv txwv li, cov neeg hlau hauv qab dej xav tau cov tshuab tso dej tawm. Rau lub hom phiaj tshwj xeeb motors, stepper motors yuav tsum tau xaiv tshwj xeeb.

Tsib, kev xaiv ntawm qhov tsis muaj load pib zaus ntawm stepper lub cev muaj zog

Tsis muaj-load pib zaus ntawm lub cev muaj zog stepper, feem ntau hu ua" idling zaus". Qhov no yog qhov taw qhia tseem ceeb rau kev yuav lub cev muaj zog. Yog hais tias nws yuav tsum tau pib thiab nres tsis tu ncua, thiab qhov ceev yog hais txog 1000 rpm (los yog siab dua), nws yog feem ntau yuav tsum" accelerate lub pib". Yog tias koj xav tau pib ncaj qha kom ua tiav kev ua haujlwm siab, nws yog qhov zoo tshaj los xaiv lub tshuab hluav taws xob reactive lossis cov hlau nplaum ruaj khov. Lub" idling zaus" ntawm cov motors no kuj siab.

Cov saum toj no yog qee qhov teeb meem uas yuav tsum tau them sai sai rau thaum xaiv lub tshuab stepper. Nov yog qee yam uas yuav tsum tau xav txog. Tau kawg, ntxiv rau cov no, tus nqi ua haujlwm ntawm lub tshuab stepper kuj tseem yog qhov yuav tsum tau xav txog. Cov yam tseem ceeb no yuav tsum tau txiav txim siab zoo thaum xaiv.
