Qhov qhib thiab kaw ntawm cov ntaub thaiv hluav taws xob ntse yog tsav los ntawm kev sib hloov ntawm micro motors. Thaum xub thawj, AC motors tau nquag siv, tab sis nrog kev nce qib hauv kev siv tshuab, DC motors tau txais kev thov dav vim lawv qhov zoo. Yog li, dab tsi yog qhov zoo ntawm DC motors siv hauv cov ntaub thaiv hluav taws xob? Cov txheej txheem tswj kev ceev yog dab tsi?
Cov ntaub thaiv hluav taws xob siv micro DC motors nruab nrog iav reducers, uas muaj lub zog siab thiab qis ceev. Cov motors no tuaj yeem tsav ntau hom kab hlau rhuav raws li qhov sib txawv ntawm kev txo qis. Feem ntau cov tshuab hluav taws xob micro DC hauv cov ntaub thaiv hluav taws xob yog cov tshuab txhuam thiab cov tshuab tsis txhuam. Brushed DC motors muaj qhov zoo xws li kev pib lub zog siab, kev ua haujlwm zoo, tus nqi qis, thiab kev tswj ceev ceev. Brushless DC motors, ntawm qhov tod tes, khav theeb lub neej ntev thiab tsis muaj suab nrov, tab sis lawv tuaj nrog cov nqi siab dua thiab ntau txoj kev tswj hwm. Yog li ntawd, ntau cov ntaub thaiv hluav taws xob hauv kev ua lag luam ntiav cov motors brushed.
Kev tswj ceev sib txawv rau Micro DC Motors hauv Hluav Taws Xob:
1. Thaum kho qhov ceev ntawm daim ntaub thaiv hluav taws xob DC lub cev muaj zog los ntawm kev txo qhov armature voltage, yuav tsum muaj DC fais fab mov regulatable rau armature circuit. Qhov kev tiv thaiv ntawm armature Circuit Court thiab excitation Circuit Court yuav tsum raug txo kom tsawg. Raws li qhov hluav taws xob txo qis, qhov ceev ntawm cov ntaub thaiv hluav taws xob DC lub cev muaj zog yuav txo qis.
2. Kev tswj ceev los ntawm kev qhia txog kev ua haujlwm ntawm lub cev muaj zog ntawm DC lub cev muaj zog. Qhov loj dua qhov kev tiv thaiv, qhov tsis muaj zog ntawm cov yam ntxwv ntawm cov neeg kho tshuab, thiab qhov nrawm nrawm dua. Ntawm qhov ceev ceev, vim yog qhov tseem ceeb ntawm kev ua haujlwm, ntau lub zog poob, thiab lub zog tso tawm qis dua. Kev tswj ceev ntau yog cuam tshuam los ntawm kev thauj khoom, txhais tau tias cov khoom sib txawv ua rau muaj kev sib txawv ntawm kev tswj ceev.
3. Tsis muaj zog magnetic ceev tswj. Txhawm rau tiv thaiv kom tsis txhob muaj qhov sib nqus ntau dhau ntawm cov hluav taws xob hauv hluav taws xob DC lub cev muaj zog, kev tswj ceev yuav tsum siv cov hlau nplaum tsis muaj zog es tsis txhob muaj zog hlau nplaum. Lub armature voltage ntawm DC lub cev muaj zog yog khaws cia ntawm nws cov nqi ntsuas, thiab cov kev ua haujlwm tsis zoo nyob rau hauv lub armature Circuit Court yog tsawg. Los ntawm kev ua kom lub zog hluav taws xob tiv thaiv Rf, qhov excitation tam sim no thiab sib nqus flux raug txo, yog li ua kom ceev ntawm cov hluav taws xob hluav taws xob DC lub cev muaj zog thiab softening cov yam ntxwv txhua yam. Txawm li cas los xij, thaum lub zog nce ntxiv, yog tias lub load torque tseem nyob ntawm tus nqi ntsuas, lub zog ntawm lub cev muaj zog yuav dhau lub zog ntsuas, ua rau lub cev muaj zog ua haujlwm dhau, uas tsis tso cai. Yog li ntawd, thaum kho qhov ceev nrog cov hlau nplaum tsis muaj zog, lub load torque yuav raug txo qis thaum lub cev muaj zog nce. Qhov no yog ib txoj kev tswj fais fab ceev ceev tas li. Txhawm rau tiv thaiv lub cev muaj zog rotor winding los ntawm kev rhuav tshem thiab puas vim yog lub zog centrifugal ntau dhau, nws yog ib qho tseem ceeb kom tsis txhob dhau qhov kev txwv ceev ntawm DC lub cev muaj zog thaum siv cov hlau nplaum tsis muaj zog.
4. Nyob rau hauv lub ceev tswj system ntawm hluav taws xob kab hlau rhuav DC lub cev muaj zog, txoj kev yooj yim mus cuag ceev tswj yog los ntawm altering lub kuj nyob rau hauv lub armature Circuit Court. Txoj kev no yog qhov yooj yim tshaj plaws, tus nqi tsim nyog, thiab siv tau rau kev tswj ceev ntawm cov ntaub thaiv hluav taws xob.
Cov no yog cov yam ntxwv thiab kev tswj ceev ntawm DC motors siv hauv cov ntaub thaiv hluav taws xob.
