Reactor Iron Loss Measurement and Evaluation

Abstract

The iron losses of three reactors are measured and compared with each other. The reactors are made of non-grain-oriented material (35H300), 6.5%Si metal (10JNEX900), and nanocrystalline soft magnetic material (FT-3M), respectively. The experiment is conducted under a condition where the supply frequency and maximum magnetic flux density are prescribed. The values are compared with those provided by the manufactures of the material and the measured iron losses of the three types of ring cores made from the respective material mentioned above. The comparison clearly indicates the dominant factor of iron loss generation.
