Y2-seriens 8-polede motor \u2014 750 o\/min. Maksimalt momentdrev<\/h2>\n

Y2-*-8 ottepolede motorserie producerer det h\u00f8jeste nominelle akselmoment af alle standard induktionsmotorer med fast frekvens i Y2-familien. Ved en synkron hastighed p\u00e5 750 o\/min (50 Hz) leverer en 8-polet motor p\u00e5 7,5 kW et nominelt moment p\u00e5 cirka 95 N\u00b7m - n\u00e6sten fire gange momentet for en 2-polet motor med identisk effekt. Denne grundl\u00e6ggende momentfordel betyder, at en enkelt 8-polet motor kan erstatte en 4-polet motor plus et 2:1 gearkassetrin, hvilket reducerer systemomkostninger, pladskrav og drivlinjekompleksitet.<\/p>\n

Korea Ever-Power producerer 21 standardmodeller i 8-polet konfiguration. Serien \u00e5bner ved ramme 80M (0,18 kW) i stedet for de mindre 63M- eller 71M-rammer, der anvendes i 2-polede og 4-polede serier, fordi de ekstra poler kr\u00e6ver st\u00f8rre statoromkreds pr. pol, hvilket n\u00f8dvendigg\u00f8r en st\u00f8rre minimumsramme. Den maksimale nominelle effekt p\u00e5 110 kW n\u00e5s ved ramme 315L.<\/p>\n

Den lave rotoroverfladehastighed p\u00e5 8-polede motorer \u2013 cirka en fjerdedel af en 2-polet motors hastighed i samme stel \u2013 resulterer i meget lav aerodynamisk st\u00f8j fra den eksterne k\u00f8leventilator. M\u00e5lte st\u00f8jniveauer p\u00e5 52-82 dB(A) i hele 8-polsomr\u00e5det er blandt de lavest opn\u00e5elige med tvungenluftk\u00f8lede induktionsmotorer, en vigtig overvejelse for st\u00f8jf\u00f8lsomme industrielle og marine milj\u00f8er. Til hastighedsstyrede applikationer med 750 o\/min. er vores YVF2 VFD-motor<\/a> deler de samme IEC-rammedimensioner.\"trefasemotor1\"<\/p>\n<\/div>\n<\/div>\n

N\u00f8gleegenskaber ved 8-polskonfigurationen<\/h2>\n
\n
\n

Maksimal drejningsmomentudgang<\/h3>\n

Ved 750 o\/min producerer en 30 kW Y2-250M-8 et nominelt drejningsmoment p\u00e5 (30 \u00d7 9550) \/ 740 = 386,9 N\u00b7m. En 4-polet motor med samme effekt ved 1480 o\/min producerer kun 193,5 N\u00b7m - pr\u00e6cis det halve. Dette fordoblede drejningsmoment betyder, at tungere belastninger, h\u00f8jere remsp\u00e6ndinger og st\u00f8rre gearkasseindgangsaksler kan h\u00e5ndteres uden at overdimensionere motorens nominelle effekt.<\/p>\n<\/div>\n

\n

Laveste ventilatorst\u00f8j<\/h3>\n

K\u00f8leventilatoren p\u00e5 en 8-polet motor roterer med 740 o\/min. \u2013 en fjerdedel af hastigheden af \u200b\u200ben 2-polet ventilator. Den aerodynamiske st\u00f8j fra ventilatorer skaleres omtrent med femte potens af tiphastigheden, s\u00e5 8-polede ventilatorer producerer dramatisk lavere akustisk st\u00f8j. St\u00f8jomr\u00e5det p\u00e5 52-82 dB(A) p\u00e5 tv\u00e6rs af Y2-8-polsomr\u00e5det er det mest st\u00f8jsvage af alle standardpolkonfigurationer i Y2-familien.<\/p>\n<\/div>\n
