Dab tsi yog Brushed Motor?
Brushed lub cev muaj zog yog ib qho tseem ceeb thiab dav siv hom hluav taws xob lub cev muaj zog uas ua haujlwm ntawm cov qauv ntawm electromagnetic induction. Nws yog tus cwj pwm los ntawm lub xub ntiag ntawm cov txhuam hniav thiab cov commutator, cov khoom siv sib xyaw ua ke uas pab txhawb kev ntws ntawm cov hluav taws xob tam sim no thiab tsav lub cev muaj zog ntawm cov khoom siv sib hloov. Nyob rau hauv ib lub cev muaj zog txhuam, cov txhuam hniav, feem ntau yog ua los ntawm cov pa roj carbon, tuav lub cev kev sib cuag nrog lub commutator, uas txuas nrog lub rotor rotor. Raws li cov hluav taws xob tam sim no ntws los ntawm cov txhuam hniav thiab cov commutator, ib qho chaw sib nqus yog tsim, ua kom lub rotor tig thiab tsim cov tshuab ua haujlwm.
Dab tsi yog Brushless Tsav?
Tsis zoo li lub tshuab ntxhua khaub ncaws, lubbrushless lub cev muaj zogua hauj lwm tsis muaj txhuam thiab ib tug commutator. Hloov chaw, nws tso siab rau kev sib hloov hluav taws xob rau kev tswj xyuas meej ntawm lub rotor's magnetic fields. Nyob rau hauv lub plawv ntawm lub brushless lub cev muaj zog tsim yog cov khoom siv hluav taws xob, xws li cov sensors (feem ntau Hall effect sensors), uas ntes lub rotor txoj hauj lwm. Cov ntaub ntawv no ua rau cov txheej txheem tswj xyuas kom meej meej synchronize lub zog ntawm lub cev muaj zog stator windings. Qhov tsis muaj txhuam tshem tawm cov teeb meem ntsig txog kev hnav, ua kom lub cev muaj zog ua haujlwm ntev.
Kev ua tau zoo sib txawv ntawm brushed thiab brushless motors
| Brushed Tsav | Brushless Tsav |
| Tsawg torque ib qhov hnyav | Ntau torque ib qhov hnyav |
| Tsawg torque ib watt | Ntau torque ib watt |
| Ntau lub suab nrov | Tsawg suab nrov |
| Lub neej luv dua | Lub neej ntev dua |
| Kev ntseeg qis dua | Kev ntseeg siab dua |
| Commutator sparking | Tsis muaj nplaim taws |
| Ntau EMI hluav taws xob | Tsawg EMI hluav taws xob |
| Tej zaum yuav xav tau airflow kom txias lub rotor | Muaj peev xwm muab kaw kom tiav |
| Tsawg RPM | Siab RPM |
| Yooj yim tsav | Nyuaj tsav |
Daim ntawv thov sib txawv
Brushed motors feem ntau yog siv hauv cov khoom siv hauv tsev thiab kev siv me me. Lawv cov qauv siv tshuab yooj yim ua rau cov tshuab txhuam hniav tsim nyog rau ntau qhov xwm txheej nrog tus nqi qis thiab kev tswj tau yooj yim, xws li lub tshuab nqus tsev thiab cov cuab yeej hluav taws xob. Txawm li cas los xij, vim muaj kev sib txhuam thiab hnav los ntawm kev sib cuag ntawm cov txhuam hniav thiab lub rotor, txhuam cov motors muaj lub neej luv dua, tsis muaj txiaj ntsig, thiab tuaj yeem ua rau muaj qee yam suab nrov thiab electromagnetic cuam tshuam.
Piv txwv li,brushless motorsyog dav siv nyob rau hauv daim ntawv thov qhov twg efficiency, durability, thiab tswj yog xav tau ntau. Brushless motors yog tswj los ntawm hluav taws xob es tsis siv cov tshuab txhuam, zam cov teeb meem hnav thiab tsim kua muag los ntawm cov txhuam hniav, thiab yog li feem ntau muab kev ua haujlwm siab dua thiab lub neej ntev dua. Lawv feem ntau siv nyob rau hauv cov cheeb tsam xws li tsheb fais fab, aerospace, thiab cov cuab yeej precision, qhov twg tswj cov lus tsa suab thiab suab nrov yog qhov tseem ceeb dua.
