Nyob rau hauv lub ntiaj teb no ntawm ntau yam hoods, kev xaiv ntawm lub cev muaj zog plays lub luag hauj lwm tseem ceeb nyob rau hauv kev txiav txim nws cov kev ua tau zoo thiab efficiency. Hais txog kev xaiv lub cev muaj zog, kev sib piv ntawm DC motors thiab AC motors tau nyiam ntau yam vim tias xaiv cov motors sib txawv yuav ua rau muaj qhov sib txawv ntawm cov khoom siv ua haujlwm thiab lub zog ua haujlwm:
Kev sib piv zog Efficiency:
Raws li kev tshawb fawb los ntawm Tuam Tshoj Lub Tsev Hluav Taws Xob Hluav Taws Xob Tshawb Fawb Lub Tsev Haujlwm, DC motors nthuav tawm lub zog zoo dua piv rau qhov sib npaug ntawm - ntsuas AC motors. Cov kev tshawb fawb tshawb pom qhia tias DC motors tuaj yeem ua tiav lub zog ntawm ntau dua 90%, thaum AC motors feem ntau ua haujlwm ntawm thaj tsam 80%. Qhov kev ua tau zoo dua ntawm DC motors yog vim lawv qhov tsim tau zoo dua, uas ua rau muaj kev hloov pauv ntawm hluav taws xob zoo dua rau hauv lub zog siv tshuab, yog li txo cov khoom siv hluav taws xob.
Tswj ceev:
Raws li kev tshawb fawb los ntawm American Society of Mechanical Engineers (ASME), DC motors muab kev yooj yim dua thiab kev hloov kho hauv kev tswj ceev. Kev tshawb fawb qhia tias qhov ceev ntawm DC lub cev muaj zog tuaj yeem tswj tau los ntawm kev kho qhov hluav taws xob lossis siv cov mem tes -width modulation (PWM). Qhov tshwj xeeb no tso cai rau DC motors los ua kom haum rau cov kev xav tau dav dua hauv cov hoods.
Pib yam ntxwv:
Kev tshawb fawb los ntawm European Commission's Joint Research Center (ECN) qhia tias DC motors muaj siab dua pib torque thiab ceev pib yam ntxwv. Txoj kev tshawb no qhia tias DC motors feem ntau pom ntau dua 30% siab dua pib torque piv rau qhov sib npaug - ntsuas AC motors. Qhov no txhais tau tias ntau lub hoods nruab nrog DC motors tuaj yeem pib thiab nres sai dua, muab kev ua haujlwm zoo dua thiab ua haujlwm.
Noise Levels:
Ib txoj kev tshawb fawb los ntawm Westfälische Hochschule hauv lub teb chaws Yelemees qhia tias DC motors feem ntau ua haujlwm ntawm cov suab nrov qis dua piv rau AC motors. Cov kev tshawb fawb pom tau hais tias lub suab nrov ua haujlwm ntawm DC motors tuaj yeem raug txo los ntawm 5-10 decibels. Qhov no yog qhov tseem ceeb tshwj xeeb hauv tsev, vim nws ua rau muaj kev ua noj ua haus ntsiag to.
DC motors tau qhib cov kev muaj peev xwm no, thawb cov ciam teb ntawm cov hood ntau npaum li cas tuaj yeem ua tiav. Raws li kev siv thev naus laus zis thiab kev tsim kho tshiab txuas ntxiv mus vam meej, peb tuaj yeem cia siab tias yuav muaj kev txhim kho zoo tshaj plaws nyob rau hauv thaj tsam ntawm ntau yam hoods, uas tau tsav los ntawm kev nrhiav tsis tu ncua ntawm kev ua tau zoo, kev ua tau zoo, thiab kev ruaj khov.
