Yaskawa EV Motor – New Wire Shape Eliminates Rare-Earth Magnets

Benji Jerew — Fri, 18 Jan 2013 16:07:56 +0000

Some of the world’s most powerful magnets, not including electromagnets, are made from the rare-earth metals neodymium, samarium, or yttrium. As a result, rare-earth magnets are expensive, while magnets made of iron, ferrite magnets, are cheaper, but not nearly as strong. Electric motors only function because of magnetism, and can be made up of arrangements of […]

We all know electric motors are torqueful, but there's a price to be paid for all that torque. Since electric cars use motors that have rare earth metals inside, they're also expensive. A team of researchers at the Tokyo University of Science has discovered how electric motors can be made from cheaper and more convenient materials.

The Hybrid Field Motor: Using Half Rare-Earth Magnets, Cheaper, Same Performance for EVs

The hybrid field motor works by generating a magnetic force by synchronizing a permanent magnet and an electromagnet. The main advantage is that hybrid field motors only use half of the amount of rare-earth magnet, compared to a synchronous motor, that you can see in today's hybrid or electric vehicles.
