Toyota is said to be trying to develop an electric motor that uses no rare earth metals?
What's the big deal. Over 40 yrs. ago right here in the U.S. I saw an electric motor with carbon fields that were(permanent magnets), compressed carbon and they were just glued to the inside of the motor case, A complete motor could be made entirely of carbon very easily. Why haven't we done so here in the U.S.?

Perhaps because we use AC motors which also do not require rare earth metals.
Also "rare Earth metals are not uncommon as the name would suggest. [ http://blogs.smithsonianmag.com/science/2010/11/ra... ] China has not only a large supply but cheap labor and as technology followed the economics, a leading industry. The US, Australia, and Mongolia , Greenland and other places also have such metals.

"Develop a motor that uses no rare earth metals"
Really? They can't just use iron? Iron is not rare at all, and it's probably the first thing that comes to mind when you say "magnet" (except Mormons, but that's another topic). And you can make permanent magnets from iron.
