© 2019 IEEE. This paper presents the results of experimental trials carried out on a permanent magnet motor with an amorphous stator core. The magnetization performances and iron loss characteristics of the manufactured amorphous core were measured. Losses of two permanent magnet motors with amorphous core and silicon steel core were calculated and compared by considering the influences of mechanic stresses induced in the amorphous core manufacturing processes. Total losses and efficiencies of the permanent magnet motors were tested and compared. It is demonstrated that the efficiency superiority of the permanent magnet motor with an amorphous core gets weaken as the load ratio increases.
