Amorphous Iron: The Right Stuff for Motors?

Posted June 17, 2014 12:00 AM by Engineering360 eNewsletter

Engineers should know a couple of things about amorphous iron: it's not hard to come by and there are good reasons for using it in motors, according to the author of this Machine Design piece. Despite the common perception that it's an exotic material, about 100,000 tons of amorphous iron is produced each year. Motors made with the material - which until recently have been limited mainly to academic studies - offer both low switching losses and lower flux density, making them suitable for higher-frequency motor applications. In addition to discussing advantages and possible designs of amorphous iron motors, the author looks at issues that are holding them back.
