Direct reuse stratégies of rare earth permanent magnets for PM electrical machines - an overview study

Abstract

International audienceThe global supply of heavy rare earth magnets can become risky with the soaring demand of rare earth permanent magnet (PM) machines. One of the promising solutions is to reuse or recycle perma¬nent magnets from end-of-Life electrical machines. This paper is an overview study of the state-of-the-art permanent magnet reuse and recycling research for electrical machines. Some méthodologies for quantifying the recyclability of permanent magnet of electrical machines are also introduced
