A quote from an article about Toyota Hybrids on the hybridcars.com website
-

'For about two years, media reports have stirred fears about a possible
shortage of rare-earth metals needed for hybrid and electric cars. According
to these reports, a shortage could threaten future production of hybrids and
EVs. Today, *Bloomberg*<http://www.bloomberg.com/news/2011-01-14/toyota-rea=
dying-electric-motors-that-don-t-use-rare-earths.html>and
others are reporting that Toyota is developing a workaround:
development
of inductive motors that don=92t need rare-earth metals. These motors could
also be lighter and more efficient than the magnet-type motor now used in
hybrid cars, like the Toyota
Prius<http://www.hybridcars.com/compacts-sedans/toyota-prius-overview.html>
.'

I'm wrong in thinking that inductive and synchronous AC motors have been
around for quite some time? Like almost 100 years. How is this a
workaround? Were rare earth magnets so cheap that it didn't make sense to
build inductive motors?

Please read the e-Book:
"The Prius that shook the world".
It is clearly revealed that they considered all types
of motors and in the end deliberately choose PM motors
because the efficiency was higher than other solutions.

I wonder if they found "new evidence" to make the claim
that without magnets the efficiency can be higher...

I love it: inductive motors.

The "new" motors apparently require inductive reasoning in their design
process. We all know that design of the old PM motors required mainly
deductive reasoning. Another article claimed that the new motor would use
electromagnets. That just doesn't seem reasonable... how could there
possibily be any connection between electricity and magnetism... or
electromagnetism and motors?

I should send out a press release: "Inventor Finds new Use for Old Metal:
We all know that copper can have health benefits when used in bracelets, and
can be used in pots and pans to improve the taste of chili. Ken Fry has
found a way to make this old metal move a car! Using skinny but incredibly
long cylinders of this metal (which Fry has dubbed "wires") wound around
what he calls an armchair... "

That's great, Ken! Thanks for my laugh of the day! :)

The sad truth is, there would be reporters that would happily snap it up
and publish it. :-(
