Qhov qhib thiab kaw ntawm cov ntaub thaiv hluav taws xob ntse yog tsav los ntawm kev tig ntawm cov micro motors. Thaum xub thawj, AC motors feem ntau siv, tab sis nrog kev nce qib ntawm thev naus laus zis, DC motors tau txais kev siv dav dav vim lawv cov txiaj ntsig. Yog li, cov txiaj ntsig ntawm DC motors siv rau hauv cov ntaub thaiv hluav taws xob yog dab tsi? Cov txheej txheem tswj ceev yog dab tsi?
Cov ntaub thaiv hluav taws xob siv cov micro DC motors uas muaj cov iav reducers, uas muaj torque siab thiab qis ceev. Cov motors no tuaj yeem tsav ntau hom ntaub thaiv raws li qhov sib txawv ntawm kev txo qis. Cov micro DC motors feem ntau hauv cov ntaub thaiv hluav taws xob yog brushed motors thiab brushless motors. Brushed DC motors muaj qhov zoo xws li torque pib siab, kev ua haujlwm du, tus nqi qis, thiab kev tswj ceev yooj yim. Brushless DC motors, ntawm qhov tod tes, muaj lub neej ntev thiab suab nrov qis, tab sis lawv tuaj nrog tus nqi siab dua thiab cov txheej txheem tswj hwm nyuaj dua. Yog li ntawd, ntau cov ntaub thaiv hluav taws xob hauv khw siv brushed motors.
Cov Txheej Txheem Tswj Ceev Sib Txawv rau Micro DC Motors hauv Cov Ntaub Thaiv Hluav Taws Xob:
1. Thaum kho qhov ceev ntawm lub tshuab hluav taws xob DC los ntawm kev txo qhov hluav taws xob ntawm lub armature, yuav tsum muaj lub zog DC uas tswj tau rau lub voj voog armature. Qhov tsis kam ntawm lub voj voog armature thiab lub voj voog excitation yuav tsum raug txo kom tsawg. Thaum qhov hluav taws xob txo qis, qhov ceev ntawm lub tshuab hluav taws xob DC yuav txo qis.
2. Kev tswj qhov ceev los ntawm kev qhia txog kev tiv thaiv series hauv lub voj voog armature ntawm DC lub cev muaj zog. Qhov loj dua qhov kev tiv thaiv series, qhov tsis muaj zog ntawm cov yam ntxwv kho tshuab, thiab qhov ceev tsis ruaj khov. Ntawm qhov ceev qis, vim muaj qhov kev tiv thaiv series tseem ceeb, ntau lub zog poob, thiab lub zog tso zis qis dua. Qhov ntau ntawm kev tswj qhov ceev yog cuam tshuam los ntawm qhov load, txhais tau tias cov load sib txawv ua rau muaj kev cuam tshuam ntawm kev tswj qhov ceev sib txawv.
3. Kev tswj qhov ceev ntawm lub zog sib nqus tsis muaj zog. Txhawm rau kom tsis txhob muaj zog ntau dhau ntawm lub voj voog sib nqus hauv lub tshuab hluav taws xob DC, kev tswj qhov ceev yuav tsum siv lub zog sib nqus tsis muaj zog es tsis txhob siv lub zog sib nqus muaj zog. Lub zog hluav taws xob ntawm lub tshuab DC raug tswj hwm ntawm nws tus nqi ntsuas, thiab qhov tsis kam ntawm cov koob hauv lub voj voog armature raug txo qis. Los ntawm kev nce qhov tsis kam ntawm lub voj voog excitation Rf, qhov tam sim no excitation thiab lub zog sib nqus raug txo qis, yog li ua rau qhov ceev ntawm lub tshuab hluav taws xob DC thiab ua kom cov yam ntxwv kho tshuab mos. Txawm li cas los xij, thaum qhov ceev nce, yog tias lub zog thauj khoom tseem nyob ntawm tus nqi ntsuas, lub zog ntawm lub cev muaj zog yuav tshaj qhov zog ntsuas, ua rau lub cev muaj zog ua haujlwm ntau dhau, uas tsis raug tso cai. Yog li ntawd, thaum kho qhov ceev nrog lub zog sib nqus tsis muaj zog, lub zog thauj khoom yuav txo qis raws li qhov ceev ntawm lub cev muaj zog nce. Qhov no yog txoj kev tswj qhov ceev ntawm lub zog tas li. Txhawm rau kom tsis txhob muaj kev rhuav tshem thiab puas tsuaj rau lub zog centrifugal ntau dhau, nws yog ib qho tseem ceeb kom tsis txhob tshaj qhov txwv ceev ntawm lub cev muaj zog DC thaum siv kev tswj qhov ceev ntawm lub zog sib nqus tsis muaj zog.
4. Hauv lub kaw lus tswj qhov ceev ntawm lub tshuab hluav taws xob DC, txoj hauv kev yooj yim tshaj plaws los ua kom tiav qhov kev tswj qhov ceev yog los ntawm kev hloov pauv qhov tsis kam hauv lub voj voog armature. Txoj kev no yog qhov yooj yim tshaj plaws, pheej yig tshaj plaws, thiab siv tau rau kev tswj qhov ceev ntawm cov ntaub thaiv hluav taws xob.
Cov no yog cov yam ntxwv thiab cov txheej txheem tswj qhov ceev ntawm DC motors siv rau hauv cov ntaub thaiv hluav taws xob.
