Motors without Rare Magnets: What are the Options? (Part One)Lower-cost motor technologies exist that can be an attractive alternative to neo-based BL PM motors – and are not subject to unpredictable supply chains
By George Holling
Almost no day passes without a major news article that discusses the very real possibility that China may use its rare earth supply as a weapon in the ongoing trade war.
