Qhov txawv ntawm DC motor thiab stepper motor

Stepper motors yog qhov tshwj xeeb DC brushless lub cev muaj zog uas yuav tsum muaj DC tsav thiab tsav tsheb sib hloov. Txawm li cas los xij, vim hais tias cov yam ntxwv ntawm cov lus tsa suab yog qhov sib txawv ntawm DC brushless motors, stepper motors tau muab faib ua cov khoom sib cais. DC motors tau muab faib ua DC brushed motors thiab DC brushless motors. Feem ntau hais lus, DC motors feem ntau xa mus rau DC brushed motors. Lub brushed DC lub cev muaj zog yuav tig ntev li ntev raws li qhov tsim nyog voltage yog thov, thiab tus naj npawb ntawm cov lem yog nyuaj rau tswj kom meej; thaum lub tshuab stepper ua haujlwm raws li kev sib tw thiab tuaj yeem tig ntawm lub kaum sab xis me me, thiab cov kev tswj hwm kuj txawv.

1. Stepping lub cev muaj zog

1. Lub stepper lub cev muaj zog tuaj yeem paub qhov tseeb ntawm kev tswj lub cev muaj zog thiab txoj haujlwm. Feem ntau, qhov tseeb ntawm stepper lub cev muaj zog yog nyob rau hauv 5% ntawm lub kaum sab xis, thiab tsis muaj qhov yuam kev tau sau tseg.

2. Lub stepping motor yuav tsum tau tsav ua ntej nws tuaj yeem khiav. Lub teeb liab tsav tsheb yuav tsum yog lub teeb liab mem tes. Thaum tsis muaj mem tes, lub kauj tsheb kauj vab yog nyob ruaj ruaj. Yog tias qhov teeb liab tsim nyog tau ntxiv, nws yuav tig ntawm lub kaum ntse ntse (hu ua lub kaum sab xis). . Qhov ceev ntawm kev sib hloov yog proportional rau zaus ntawm pulses.

3. Kev hloov pauv ntawm cov pulses tuaj yeem hloov tau yooj yim ntawm kev sib hloov. Yog li ntawd, cov khoom siv xws li tshuab luam ntawv, plotters, thiab robots siv stepping motors ua lub zog tseem ceeb.

4. Qhov siab tshaj plaws kub tau tso cai rau ntawm qhov chaw ntawm lub tshuab stepping. Kev kub siab dhau ntawm lub kauj ruam yuav ua ntej demagnetize cov khoom sib nqus ntawm lub cev muaj zog, ua rau txo qis ntawm lub zog thiab txawm tias tawm ntawm kauj ruam. Yog li ntawd, qhov siab tshaj plaws kub tso cai rau saum npoo ntawm lub cev muaj zog yuav tsum nyob ntawm qhov demagnetization point ntawm cov khoom sib nqus sib txawv ntawm lub cev muaj zog; Feem ntau hais lus, demagnetization ntawm cov khoom sib nqus Cov ntsiab lus yog tag nrho saum toj no 130 degrees Celsius, thiab qee qhov txawm tias siab li 200 degrees Celsius, yog li qhov kub ntawm sab nraud ntawm stepper lub cev muaj zog tag nrho ntawm 80-90 degrees Celsius.

5. Lub torque ntawm lub stepper lub cev muaj zog yuav txo nrog qhov nce ntawm qhov ceev. Thaum lub stepper lub cev muaj zog tig, lub inductance ntawm txhua theem winding ntawm lub cev muaj zog yuav tsim ib tug rov qab electromotive quab yuam; qhov siab dua qhov zaus, qhov ntau dua qhov rov qab electromotive quab yuam. Raws li nws qhov kev nqis tes ua, theem tam sim no ntawm lub cev muaj zog txo qis raws li qhov zaus (lossis ceev) nce, ua rau txo qis ntawm lub zog.

6. Lub stepper lub cev muaj zog tuaj yeem khiav ib txwm ntawm qhov qis qis, tab sis nws tsis tuaj yeem pib thaum lub nrawm nrawm dua li qee qhov ceev, thiab nws yuav nrog lub suab nrov nrov. Stepper lub cev muaj zog muaj ib qho kev ntsuas: tsis muaj-load pib zaus, uas yog, cov mem tes zaus uas lub stepper lub cev muaj peev xwm pib ib txwm nyob rau hauv tsis muaj-load tej yam kev mob. Yog hais tias tus mem tes zaus siab dua li tus nqi no, lub cev muaj zog tsis tuaj yeem pib ib txwm, thiab cov kauj ruam poob lossis nres yuav tshwm sim. Nyob rau hauv load, qhov pib zaus yuav tsum qis dua. Yog tias koj xav ua kom lub cev muaj zog tig ntawm kev kub ceev, cov mem tes zaus yuav tsum muaj cov txheej txheem acceleration, uas yog, qhov pib zaus qis, thiab tom qab ntawd nce mus rau qhov xav tau siab zaus ntawm qee qhov kev nrawm (lub cev muaj zog nce los ntawm qis ceev. mus rau kev kub ceev). Nrog nws cov yam ntxwv zoo kawg li, stepper motors ua lub luag haujlwm tseem ceeb hauv lub sijhawm ntawm digital manufacturing. Nrog rau kev txhim kho ntawm cov thev naus laus zis sib txawv thiab kev txhim kho ntawm cov tshuab stepper motors, stepper motors yuav siv rau hauv ntau qhov chaw.

2. DC lub cev muaj zog

Lub tshuab hluav taws xob DC yog lub tshuab hluav taws xob hloov hluav taws xob uas hloov DC lub zog hluav taws xob rau hauv lub zog hluav taws xob (DC lub cev muaj zog) lossis hloov lub zog hluav taws xob mus rau DC hluav taws xob hluav taws xob (DC generator). Nws yog lub cev muaj zog uas tuaj yeem hloov DC lub zog hluav taws xob thiab lub zog txhua yam rau ib leeg. Thaum nws ua haujlwm raws li lub cev muaj zog, nws yog DC lub cev muaj zog, uas hloov hluav taws xob hluav taws xob rau hauv lub zog siv tshuab; Thaum nws ua haujlwm raws li lub tshuab hluav taws xob, nws yog lub tshuab hluav taws xob DC, uas hloov cov tshuab hluav taws xob rau hauv hluav taws xob. Xws li DC generators thiab DC motors. DC motors tau muab faib ua DC brushed motors thiab DC brushless motors. DC brushless motors xav tau tus neeg tsav tsheb kom ua tiav kev sib hloov hluav taws xob, uas yog kim tab sis muaj lub neej ntev thiab suab nrov; DC brushed motors yog tus nqi qis thiab siv tau yooj yim, tab sis muaj lub neej luv luv thiab lub suab nrov.
