The effective permeability of Fe-based amorphous alloy is obviously higher than that of silicon steel with high saturation magnetic induction strength and Bs value of 1.56T. The loss of Fe-based amorphous alloy at high frequencies is significantly lower than that of silicon steel. For motors with operating frequencies ranging from hundreds to thousands of Hz, Fe-based amorphous alloy is superior to silicon steel.
High saturation induction of 1.56 Tesla—Reducing component volume.
Low coercivity—Increasing component efficiency.
Low core loss—Reducing temperature rise in devices.
Variable permeability by different heat treatments—Satisfying various application requirements.
Excellent thermal stability—Having a highest service temperature of 130oC.
Favorable for motor miniaturization
