Abstract
Core losses of an 18.5 kW asynchronous motor were measured and computed, by means of a suitable electromagnetic fields package, improved for core loss calculation. The results show that a 1 to 3% improvement in efficiency is possible by replacing the conventional soft laminations by new materials. The differences between measurement and computation are mainly attributed to rotating fields inside the stator
