When using amorphous material in an electric motor, the losses are often higher than expected. This paper investigates the effect of cutting and annealing on the performance of amorphous material. The BH-curve and losses are compared before and after an annealing treatment. Furthermore, the properties are compared for material cut with a plate shear and cut by laser, followed by an annealing treatment. A case study is done for a high speed motor, comparing the amorphous material with a conventional silicon steel grade. Based on a FEM analysis, a reduction of iron loss by a factor 7 is found through the use of an amorphous material instead of a conventional silicon steel.
