Ntsuas Efficiency:
Kev ua tau zoo hauv DC brushed lub cev muaj zog tuaj yeem ntsuas tau siv ntau txoj hauv kev. Ob txoj kev siv feem ntau yog:
1. Direct Measurement Method: Txoj kev no suav nrog ntsuas lub zog tawm tswv yim siv lub ntsuas hluav taws xob hluav taws xob thiab lub zog tso zis siv lub dynamometer. Qhov kev ua tau zoo yog xam raws li qhov piv ntawm cov zis hluav taws xob rau lub zog input.
2. Indirect Measurement Method: Nyob rau hauv txoj kev no, qhov ua tau zoo yog xam los ntawm kev ntsuas lub cev muaj zog poob, suav nrog tooj liab poob, hlau poob, kev sib txhuam losses, thiab windage poob. Cov kev poob no yog rho tawm los ntawm lub zog input kom tau txais lub zog tso zis. Qhov kev ua tau zoo yog xam raws li qhov piv ntawm cov zis hluav taws xob rau lub zog input.
Qhov tseem ceeb ntawm Kev Txhim Kho Kev Ua Haujlwm:
Txhim kho qhov ua tau zoo ntawm DC brushed motors coj ntau yam txiaj ntsig thoob plaws ntau daim ntawv thov:
1. Kev txuag hluav taws xob: Kev ua haujlwm siab dua txhais tau tias txo qis kev siv hluav taws xob, ua rau kev txuag hluav taws xob thiab muaj peev xwm ua haujlwm qis dua. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov motors khiav mus rau lub sijhawm ntev, xws li HVAC systems lossis cov tshuab ua haujlwm.
