Dab tsi yog qhov txawv ntawm brushed DC thiab brushless DC motors? Yuav xav txog dab tsi thaum xaiv lub cev muaj zog

Qhov sib txawv tseem ceeb ntawm brushed thiab brushless motors yog lub neej ntev. Txhuam motors muaj lub neej luv luv thiab raug txwv los ntawm txhuam hnav, thaum brushless motors muaj ntau lub pob bearing hnav.

Rau ntau daim ntawv thov, lub neej luv luv ntawm lub cev tsis muaj zog tsis yog qhov teeb meem, vim nws tuaj yeem tsim nrog tus nqi qis. Lub neej kev pab cuam yuav txawv ntawm 100 mus rau 10,000 teev, nyob ntawm seb yam xws li kev thauj khoom tam sim no, ceev, vibration thiab thim rov qab zaus, nrog rau qhov nruab nrab ntawm 2,000 teev. Ntawm qhov tod tes, brushless motors muaj peev xwm muab tau kaum tawm txhiab teev ntawm lub neej.

Lwm qhov kev xav yog ceev. Feem ntau, brushed motors muaj qhov siab tshaj plaws ntawm 20, 000 RPM, tab sis nyob rau hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob no nce ntau, txo cov kev pab cuam lub neej. Hauv kev xyaum, txhuam cov motors feem ntau khiav qis dua 10, 000 RPM. Brushless motors ntawm qhov loj me thiab sib nqus tsim tuaj yeem ua haujlwm ntawm qhov nrawm dua, txog li 100, 000 RPM hauv qee kis. Cov no yog cov motors zoo tagnrho rau cov ntawv thov uas ceev yog qhov tseem ceeb.

Tab sis cov no yog generalizations. Koj yuav tsum tshawb xyuas txhua daim ntawv qhia lub cev muaj zog kom paub meej cov ntaub ntawv ntawm kev ceev thiab lub peev xwm torque.

Ib puag ncig tej yam kev mob yog lwm yam. Yog hais tias electromagnetic cuam tshuam yog ib qho kev txhawj xeeb, lub tshuab txhuam hniav yuav tsis haum vim muaj qhov tshwm sim hu ua txhuam hluav taws. Nyob rau hauv cov huab cua tawg, txhuam sparks yog ib qho teeb meem loj. Cov txhuam hniav ua los ntawm graphite yuav tsum muaj huab cua noo thiab oxygen kom ua haujlwm zoo thiab tsim cov plua plav uas tuaj yeem ua kom huv huv, lub tshuab nqus tsev siab lossis cov khoom siv kho qhov muag.

Vim li no, feem ntau cov motors rau ib puag ncig tshwj xeeb yog brushless. Tsis muaj lub cev txhuam residue los yog spark-related emissions. Brushless motors tsis yog qhov pov thawj tawg, tab sis tuaj yeem ua tau yooj yim nrog kev hloov kho tshwj xeeb. Lawv tuaj yeem ua kom tsis muaj menyuam thiab ua haujlwm hauv ultra-siab daim ntawv thov lub tshuab nqus tsev uas xav tau preheating, ua rau lawv zoo tagnrho rau kev siv kho mob. Brushless motors kuj tuaj yeem tiv taus qhov siab ntawm kev co thiab kub siab.

Tsis muaj lub cev muaj zog yog qhov yooj yim li lub cev muaj zog DC, tsuas yog siv lub zog los ua kom lub cev muaj zog. Brushless motors xav tau cov tswj hluav taws xob thiab cov kab txuas ntxiv, ntxiv qhov nyuaj thiab tus nqi. Txawm li cas los xij, qhov zoo dua no yog tsis pom zoo hauv cov ntawv thov uas yuav tsum muaj kev tswj hwm qib siab, qhov twg ob qho tib si brushed thiab brushless motors xav tau ib tug maub los tswj lub cev muaj zog ceev, ncej txoj hauj lwm los yog torque tawm tswv yim.

Yog li, txawm tias txhuam los yog tsis txhuam, thaum kawg, koj yuav tsum xaiv raws li qhov ceev, ntev, kev teeb tsa tsis yooj yim thiab ib puag ncig ntawm koj daim ntawv thov tshwj xeeb.
