New Trends in the High Efficiency Motors Market Utilizing Amorphous and Nanocrystalline Soft Magnetic Materials
Eric Theisen, Director of Research & Development, Metglas, Inc.
Here we update the status of the advances in Fe-based amorphous and nanocrystalline soft magnetic alloys currently used in the market and highlight their primary industrial applications. Emerging trends with electric motors utilize these advancements fabrication methods. There are many approaches to incorporate amorphous ribbon into the motor components and we will discuss the methods that have been industrially adopted. FeCo based amorphous alloys further enhance the induction levels (1.8T) and can be viable in these applications. There are also new FeCo and FeNi nanocrystalline alloys being developed specifically suited towards motor applications that will be discussed.
