摘要： Electric machines can be improved or uprated to reduce core-end losses using lower core loss material such as high grade iron silicon. A machine uprating entails removing at least a last one of the stacked lamination packages at each end of the stator core, and re-stacking the removed lamination packages with the lower core loss material.
