Qhov qhib thiab kaw ntawm ntse hluav taws xob curtains cia siab rau kev sib hloov ntawm micro motors kom ua tiav. Qee lub tshuab hluav taws xob siv hluav taws xob siv AC lub cev muaj zog, tab sis nrog kev nce qib ntawm kev siv tshuab, micro DC motors tau dav siv rau ntau yam khoom siv hluav taws xob. 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 lub tshuab hluav taws xob micro DC nrog cov iav reducers, uas muaj qhov zoo ntawm qhov siab torque thiab qis ceev, thiab tuaj yeem tsav ntau hom kab hlau rhuav raws li qhov sib txawv ntawm kev txo qis. Common micro DC motors nyob rau hauv hluav taws xob curtains yog txhuam motors thiab brushless motors. Lub ntsiab zoo ntawm brushed DC motors muaj xws li siab pib torque, du ua hauj lwm, tsis muaj nqi, thiab yooj yim tswj ceev; brushless DC motors muaj qhov zoo ntawm lub neej ntev thiab tsis tshua muaj suab nrov, tab sis lawv cov nqi siab dua, thiab kev tswj xyuas ntau dua. Yog li ntawd, muaj ntau yam hluav taws xob curtains nyob rau hauv kev ua lag luam uas siv brushed motors.
Kev tswj ceev sib txawv rau Micro DC Motors hauv Hluav Taws Xob
1. Thaum qhov ceev ntawm cov ntaub thaiv hluav taws xob DC lub cev muaj zog tau hloov kho los ntawm kev txo qhov armature voltage, armature Circuit Court yuav tsum tau tswj DC fais fab mov, thiab qhov kev tiv thaiv ntawm armature circuit thiab excitation Circuit Court yuav tsum tsawg li tsawg tau. Thaum qhov hluav taws xob txo qis, qhov ceev ntawm cov ntaub thaiv hluav taws xob DC lub cev muaj zog kuj tseem yuav txo qis.
2. Ceev tswj los ntawm series kuj nyob rau hauv lub armature Circuit Court ntawm lub DC lub cev muaj zog, qhov loj dua lub series kuj, lub zog tsis muaj zog ntawm cov neeg kho tshuab yam ntxwv, thiab ntau unstable ceev. Nyob rau hauv qis speeds, vim lub series loj kuj, ntau zog poob, thiab lub hwj chim yog tsawg. Kev tswj ceev ntau yog cuam tshuam los ntawm kev thauj khoom, uas yog, cov khoom sib txawv ua rau muaj kev sib txawv ntawm kev tswj ceev.
3. Tsis muaj zog sib nqus ceev tswj, kom tsis txhob muaj cov hlau nplaum hluav taws xob ntawm cov ntaub thaiv hluav taws xob DC lub cev muaj zog los ntawm kev saturated, 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 tus nqi ntsuas, thiab cov kev ua haujlwm tsis zoo nyob rau hauv lub armature Circuit Court yog tsawg. Lub excitation tam sim no thiab sib nqus flux yog txo los ntawm kev ua kom lub excitation Circuit Court tsis kam Rf, yog li ua kom ceev ntawm lub hwj chim DC lub cev muaj zog thiab softening cov neeg kho tshuab yam ntxwv. Thaum qhov ceev nce, yog tias lub load torque tseem nyob ntawm tus nqi ntsuas, lub zog 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 tsis muaj zog sib nqus ceev tau hloov kho, lub load torque yuav txo qis sib xws nrog qhov nce ntawm lub cev muaj zog. Qhov no yog lub zog ceev ceev tswj. Txhawm rau tiv thaiv lub cev muaj zog rotor winding los ntawm kev rhuav tshem thiab puas vim yog lub zog centrifugal ntau dhau, kev saib xyuas yuav tsum tau them kom tsis pub dhau qhov kev tso cai ntawm DC lub cev muaj zog ceev thaum siv cov hlau nplaum tsis muaj zog.
4. Nyob rau hauv kev tswj ceev ceev ntawm lub tshuab hluav taws xob DC lub cev muaj zog, txoj kev yooj yim tshaj plaws los ua kom tiav qhov kev tswj ceev yog los ntawm kev hloov cov kev tiv thaiv hauv armature circuit. Txoj kev no yog qhov yooj yim tshaj plaws thiab muaj tus nqi qis tshaj plaws, thiab nws yog qhov ua tau zoo heev 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.
