Descrizione del motore

The YKK series of high-efficiency air-cooled asynchronou sthree-phase motors complies with the IEC standard. In order to achieve a significant market share, it is essential that high-efficiency motors meet national/regional standards for assigned powers in relation to mechanical dimensions (such as chassis size, flanges). There are several national/regional standards for chassis assignment (EN 50347, JIS C 4212, NBR 17094, NEMA MG13, SANS 1804 and others), but there is no IEC standard. As this standard (IEC 60034-30-1) defines energy efficiency classes independently of dimensional restrictions, it may not be possible in all markets to produce motors with higher efficiency classes and maintain the mechanical dimensions of the national/regional standards.

IE codes are not limited to motors, but can be used to classify other components, such as frequency converters and gearboxes. However, other components are expected to be classified with a comparable system: IE1 meaning low efficiency up to IE5 meaning the highest efficiency. Combinations of components (such as power drive systems) will need a combined efficiency rating. This rating should not be an IE code to avoid confusion. It will be defined in other IEC standards. The efficiency levels in this standard for 50 Hz and 60 Hz are not always entirely consistent across all pole numbers and the entire power range.
