Ved delvis belastning (under 75% af nominel effekt) kan den relative forskel mellem IE3- og IE4-effektiviteten mindskes en smule afh\u00e6ngigt af balancen af \u200b\u200btab i hvert design. Begge n\u00e5r typisk en maksimal effektivitet mellem 70 og 90 procent belastning. IE4-fordelen er mest konsistent og forudsigelig ved eller n\u00e6r fuld belastning ved kontinuerlig drift, hvilket er den tilstand, IE-klassen er defineret til, og den tilstand, der er mest relevant for kontinuerligt k\u00f8rende pumpe-, ventilator- og kompressordrev.<\/p>\n<\/div>\n<\/div>\n<div style=\"border: 1px solid #bbf7d0; border-radius: 8px; overflow: hidden;\">\n<div style=\"background: #052b14; padding: 13px 18px;\">\n<div style=\"font-weight: bold; color: #fff; font-size: 14px;\">Hvorfor er en IE4-motor fysisk st\u00f8rre og tungere end en IE3 ved samme effekt?<\/div>\n<\/div>\n<div style=\"padding: 16px 20px; background: #fff;\">\n<p style=\"font-size: 15px; color: #374151; margin: 0; line-height: 1.75;\">For at opn\u00e5 IE4-effektivitet skal motordesigneren reducere tab, prim\u00e6rt ved at \u00f8ge m\u00e6ngden af \u200b\u200bkobber i statorviklingen (flere vindinger, st\u00f8rre tr\u00e5dtv\u00e6rsnit) og bruge elektrisk st\u00e5l af h\u00f8jere kvalitet. Begge \u00e6ndringer kr\u00e6ver mere materialevolumen. Stator- og rotorlamineringsstakken skal forl\u00e6nges i aksial l\u00e6ngde for at im\u00f8dekomme det ekstra kobber, samtidig med at spaltefyldningsforholdet holdes inden for de gr\u00e6nser, der muligg\u00f8r p\u00e5lidelig viklingsimpr\u00e6gnering.
