Kusiyana pakati pa ma motors a NEMA ndi ma IEC motors.

Kusiyana pakati pa ma motors a NEMA ndi ma IEC motors.

Kuyambira 1926, bungwe la National Electrical Manufacturers Association (NEMA) lakhazikitsa miyezo yama motors omwe amagwiritsidwa ntchito ku North America. NEMA imasintha pafupipafupi ndikusindikiza MG 1, yomwe imathandiza ogwiritsa ntchito kusankha ndikuyika ma mota ndi ma jenereta moyenera. Lili ndi chidziwitso chothandiza pakugwira ntchito, kuchita bwino, chitetezo, kuyesa, kupanga, ndi kupanga ma alternating current (AC) ndi ma motors and jenereta apano (DC). International Electrotechnical Commission (IEC) imakhazikitsa miyezo yama injini padziko lonse lapansi. Mofanana ndi NEMA, IEC imasindikiza muyezo 60034-1, Guide to Motors for the Global Market.

Kodi pali kusiyana kotani pakati pa muyezo wa NEMA ndi mulingo wa IEC? Magalimoto aku China amagwiritsa ntchito IEC (European standard) ndipo NEMA MG1 ndiye muyezo waku America. Kwenikweni, awiriwa ali ofanana. Koma ndi zosiyananso pang'ono m'malo ena. Muyezo wa NEMA ndi muyeso wa IEC umasiyana pakugwiritsa ntchito mphamvu zamagalimoto komanso kukwera kwa kutentha kwa rotor. Mphamvu yogwiritsira ntchito mphamvu ya injini ya NEMA ndi 1.15, ndipo mphamvu ya IEC (China) ndi 1. Njira yolembera magawo ena ndi yosiyana, koma zomwe zilipo ndizofanana.

Kufananiza kosiyana

Kawirikawiri, kusiyana kwakukulu ndi kusiyana kwakukulu kwa kukula kwa makina ndi kukhazikitsa. IEC ndiyolimba kwambiri pankhani yosindikiza. Pankhani yamagetsi, zofunikira zamagetsi za Nema zimakhala ndi zochulukira kwanthawi yayitali za 1.15 komanso zofunikira zachitetezo chapamwamba zomwe zimawonedwa mu UL.

Kuyerekeza kusiyana kwakukulu pakati pa Nema ndi IEC motors

Kuyerekeza kwa Nema ndi IEC motor base size

Ngakhale NEMA ndi IEC zili ndi zofanana zambiri, pali kusiyana kochepa pakati pa miyezo iwiri yamagalimoto. Lingaliro la NEMA limagogomezera mapangidwe olimba kuti athe kugwiritsidwa ntchito mokulirapo. Kusankha kosavuta komanso kufalikira kwakugwiritsa ntchito ndizozipilala ziwiri zofunika kwambiri pamalingaliro ake opangira; IEC imayang'ana kwambiri kugwiritsa ntchito komanso magwiridwe antchito. Kusankha zida za IEC kumafuna chidziwitso chambiri chogwiritsa ntchito, kuphatikiza kutsitsa kwagalimoto, kuzungulira kwa ntchito, ndi katundu wathunthu wapano. Kuphatikiza apo, NEMA imapanga zida zokhala ndi chitetezo chomwe chingakhale chokwera mpaka 25%, pomwe IEC imayang'ana kwambiri malo ndi kupulumutsa ndalama.

IE5 Energy Efficiency Kalasi.

Kalasi yogwira ntchito bwino ya IE5 ndi gulu la magalimoto lomwe lidakhazikitsidwa ndi International Electrotechnical Commission (IEC) lomwe limatanthawuza mphamvu zapamwamba kwambiri pamapangidwe amoto. Ku China, kalasi yabwino ya IE5 ikugwirizana ndi dzikolo's kudzipereka kukumbatira matekinoloje ogwiritsira ntchito mphamvu komanso kuchepetsa kuchuluka kwa mpweya wake. Ma motors a IE5 amapeza mphamvu zochulukirapo, kuchepetsa kutayika kwa mphamvu panthawi yogwira ntchito, kupulumutsa ndalama zambiri komanso zopindulitsa zachilengedwe.

NEMA sinapereke tanthauzo la IE5 pamsika waku North America, ngakhale opanga ena akutsatsa ma mota oyendetsedwa ndi VFD ngati.“wapamwamba-zapamwamba mphamvu.”Lingaliro lomwelo limagwiranso ntchito pakukwaniritsa magawo ofananira a IE5 okhala ndi ma liwiro osinthika pazambiri komanso pang'ono. Magalimoto ophatikizika omwe amagwiritsa ntchito ukadaulo wothandizidwa ndi ferrite ndi yankho lina lomwe limapereka magwiridwe antchito a IE5 ndikuthandizira kukhazikitsa ndikuchotsa ma waya okwera mtengo komanso nthawi yoyika.

Chifukwa chiyani kugwiritsa ntchito mphamvu kwamphamvu kuli nkhani yofala?

Ma motors ndi makina amagalimoto amatenga pafupifupi 53% yamagetsi padziko lonse lapansi. Ma motors amatha kugwiritsidwa ntchito kwa zaka 20 kapena kuposerapo, kotero mphamvu zomwe zimagwiritsidwa ntchito ndi ma motors osagwira ntchito zimadziunjikira pa moyo wa chinthucho, zomwe zimapangitsa kupsinjika kosafunika pa gridi. Poyang'ana pa kusankha galimoto yabwino kwambiri kuti ipititse patsogolo kayendetsedwe kake ndikupewa kutulutsa mpweya wa CO2, kuwononga chilengedwe komanso kupulumutsa ndalama kumatha kuchepetsedwa, zomwe zitha kuperekedwa kwa makasitomala. Kuphatikiza pa kuchepetsa mpweya wowonjezera kutentha ndi mtengo wamagetsi, ma motors ogwira ntchito amathanso kuwongolera mpweya wabwino, kuchepetsa kutha kwa zida, ndikuwonjezera kutulutsa kwa ogwiritsa ntchito.

Ubwino wa Mingteng Motor

Anhui Mingteng (https://www.mingtengmotor.com/) imapanga ndikupanga ma motors okhazikika a maginito omwe ali ndi milingo yamagetsi ndi miyeso yoyika yomwe imagwirizana kwathunthu ndi miyezo ya International Electrotechnical Commission (IEC), yokhala ndi mphamvu zowonjezera mphamvu mpaka milingo ya IE5, makina opangira magetsi okwera kwambiri omwe amapulumutsa 4% mpaka 15%. , ndi makina amagetsi otsika kwambiri omwe amapulumutsa 5% mpaka 30%. Anhui Mingteng ndiye mtundu womwe umakonda kwambiri posintha mphamvu zamagalimoto!
