N.Y. Times – A Push to Make Motors With Fewer Rare Earths

Jim Witkin. “A Push to Make Motors With Fewer Rare Earths”. The New York Times. April 20, 2012. http://www.nytimes.com/2012/04/22/automobiles/a-push-to-make-motors-with-fewer-rare-earths.html?_r=2&pagewanted=all&

QM Power, based in Lee’s Summit, Mo., has designed a motor using what it calls Parallel Path Magnetic Technology.

“Changing the orientation of the magnets allows us to couple the power from multiple magnets and create stronger magnetic fields inside the motor,” said Patrick J. Piper, chief executive of QM. “This means we can use lower-strength magnets to achieve the same power output as rare-earth magnets.”
