Umehluko phakathi kwezinjini ze-NEMA nama-IEC motors.

Umehluko phakathi kwezinjini ze-NEMA nama-IEC motors.

Kusukela ngo-1926, iNational Electrical Manufacturers Association (NEMA) ibeke izindinganiso zamamotho asetshenziswa eNyakatho Melika. I-NEMA ibuyekeza njalo futhi ishicilele i-MG 1, esiza abasebenzisi bakhethe futhi basebenzise amamotho namajeneretha ngendlela efanele. Iqukethe ulwazi olusebenzayo mayelana nokusebenza, ukusebenza kahle, ukuphepha, ukuhlola, ukukhiqizwa, kanye nokwakhiwa kwamamotho ashintshashintshayo amanje (AC) kanye namanje aqondile (DC) namajeneretha. I-International Electrotechnical Commission (IEC) ibeka amazinga ezinjini zomhlaba wonke. Ngokufana ne-NEMA, i-IEC ishicilela i-standard 60034-1, Umhlahlandlela Wezimoto Zemakethe Yomhlaba Wonke.

Uyini umehluko phakathi kwezinga le-NEMA nezinga le-IEC? Izinga lezimoto zaseChina lisebenzisa i-IEC (i-European standard) kanti i-NEMA MG1 iyindinganiso yaseMelika. Ngokuyisisekelo, kokubili kuyafana ngokuyisisekelo. Kodwa futhi kwehluka kancane kwezinye izindawo. Izinga le-NEMA nezinga le-IEC liyahluka esicini sokusebenzisa amandla emoto nokukhuphuka kwezinga lokushisa le-rotor. Isici sokusebenzisa amandla senjini ye-NEMA ngu-1.15, futhi isici samandla se-IEC (China) singu-1.Indlela yokumaka amanye amapharamitha ihlukile, kodwa okuqukethwe okubalulekile kuyefana.

Iziqhathaniso ezahlukene

Ngokuvamile, umehluko omkhulu umehluko omkhulu ngobukhulu bemishini kanye nokufakwa. I-IEC iqine kakhulu mayelana nokuvala. Ngokuya ngezidingo zikagesi, izidingo zikagesi ze-Nema zinesici sokulayishwa ngokweqile sesikhathi eside esingu-1.15 kanye nezidingo eziphezulu zokufakelwa ezivame ukubonakala e-UL.

Ukuqhathaniswa komehluko omkhulu phakathi kwe-Nema kanye ne-IEC motors

Ukuqhathaniswa kosayizi basezinjini ze-Nema kanye ne-IEC

Nakuba i-NEMA ne-IEC inokufana okuningi, kunomehluko omncane oyisisekelo phakathi kwamazinga amabili ezimoto. Ifilosofi ye-NEMA igcizelela imiklamo eqinile ukuze isetshenziswe kabanzi. Ukukhetha kalula kanye nobubanzi bokusetshenziswa yizinsika ezimbili eziyisisekelo kufilosofi yayo yokuklama; I-IEC igxile ekusetshenzisweni nasekusebenzeni. Ukukhetha imishini ye-IEC kudinga izinga eliphezulu lolwazi lohlelo, okuhlanganisa ukulayishwa kwezimoto, umjikelezo womsebenzi, nomthwalo ogcwele wamanje. Ukwengeza, i-NEMA iklama izingxenye ezinezici zokuphepha ezingase zibe phezulu njengo-25% wesici sesevisi, kuyilapho i-IEC igxile esikhaleni nokonga kwezindleko.

I-IE5 Ikilasi LokuSebenza Amandla.

Isigaba se-IE5 sokusebenza kahle siwukuhlukaniswa kwezimoto okusungulwe yi-International Electrotechnical Commission (IEC) ekhombisa izinga eliphezulu kakhulu lokusebenza kahle kwamandla ekwakhiweni kwezimoto. E-China, isigaba se-IE5 sokusebenza kahle sihambisana nezwe's ukuzibophezela ekwamukeleni ubuchwepheshe bokusebenza kahle kwamandla kanye nokunciphisa i-carbon footprint yayo. Amamotho e-IE5 afinyelela ukusebenza kahle kwamandla okuphezulu, anciphisa ukulahleka kwamandla ngesikhathi sokusebenza, azuze ukonga kwezindleko ezibalulekile kanye nezinzuzo zemvelo.

I-NEMA ayihlinzekanga ngezinga lencazelo ye-IE5 emakethe yaseNyakatho Melika, nakuba abanye abakhiqizi bekhangisa amamotho ashayelwa yi-VFD njenge“ukusebenza kahle okuthuthukisiwe.”Umqondo ofanayo uyasebenza ekuzuzeni amazinga okusebenza alinganayo e-IE5 ngamadrayivu esivinini ahlukahlukene emithwalweni egcwele neyingxenye. Amadrayivu ezimoto adidiyelwe asebenzisa ubuchwepheshe bokunqikazeka obuvumelana ne-ferrite angesinye isixazululo esiletha amazinga e-IE5 okusebenza kahle futhi senze ukusetha kube lula kuyilapho sisusa izintambo ezibizayo nesikhathi sokufaka.

Kungani ukusebenza kahle kwamandla kuyisihloko esishisayo?

Izimoto nezinhlelo zezimoto zenza cishe ama-53% okusetshenziswa kukagesi emhlabeni jikelele. Ama-motor angahlala esetshenziswa iminyaka engu-20 noma ngaphezulu, ngakho-ke amandla asetshenziswa ama-motor angasebenzi kahle aqoqana phakathi nokuphila komkhiqizo, okubangela ukucindezeleka okungadingekile kugridi. Ngokugxila ekukhetheni injini engcono kakhulu yokuthuthukisa ukusebenza kahle kohlelo lonke nokugwema ukukhishwa kwe-CO2, umthelela wendawo kanye nokonga kwezindleko kungancishiswa, okungadluliselwa kumakhasimende. Ngaphezu kokunciphisa amagesi abamba ukushisa kanye nezindleko zamandla, ama-motor asebenzayo angabuye athuthukise izinga lomoya, anciphise ukuphelelwa yisikhathi kwemishini, futhi andise ukuphuma komsebenzisi wokugcina.

Izinzuzo ze-Mingteng Motor

Anhui Mingteng (https://www.mingtengmotor.com/) ikhiqiza futhi ithuthukise izinjini ezihambisanayo zikazibuthe ezihlala unomphela ezinamazinga amandla kanye nobukhulu bokufaka obuthobelana ngokugcwele namazinga e-International Electrotechnical Commission (IEC), namazinga okusebenza kahle kwamandla afinyelela kumazinga e-IE5, amasistimu omkhiqizo wezimoto ezinamandla kakhulu ezonga u-4% kuya ku-15%. , kanye nezinhlelo zomkhiqizo wezimoto ezine-voltage ephansi ezonga u-5% ukuya ku-30%. I-Anhui Mingteng iwuphawu olukhethwayo lokuguqula ezonga amandla emoto!
