Hitachi’s New, More Efficient DC Motor Control System Could Improve EVs

Benji Jerew — Fri, 19 Apr 2013 15:58:19 +0000

For the most part, electric vehicles use an invertor to change the direct current coming from the battery pack to alternating current to power the electric motor. Direct current [DC] motors are more efficient than alternating current [AC] motors, but aren’t found very much in electric vehicle application because they waste energy starting up and […]

Protean Electric In-Wheel Electric Motors are Production-Ready

Benji Jerew — Tue, 16 Apr 2013 15:26:33 +0000

Electric vehicles are mostly designed with electric motors in place of a transmission or engine or even an axle, but Protean Electric’s in-wheel electric motors promise more efficiency and power than any other design. Power-to-weight ratio in any vehicle is directly related to both the performance and efficiency of any vehicle on the road. Maximizing […]

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 […]

Hitachi’s New Electric Motor Not Using Rare Neodymium, Could Lower Market Prices

Ovidiu Sandru — Fri, 13 Apr 2012 11:09:52 +0000

A new, highly-efficient permanent magnet synchronous motor has been unveiled by Hitachi. Nothing unusual so far. The only big and important difference between Hitachi’s new motor and everything that exists in the industry is that this one doesn’t have neodymium magnets. Neodymium magnets contain a rare-earth material, which is the cause for its high price […]

Advances in Highly-Competitional Washer/Dryer Motor Industry May Benefit Electric Vehicles

Ovidiu Sandru — Mon, 10 May 2010 14:38:28 +0000

Competition (even if at times or war) has always been the mother of technical advance. Just like those who invented variable-valve timing engine designs to reduce fuel consumption, electric appliances companies are now competing against each other to make more and more efficient and powerful electric motors for hair dryers/washers. All these could benefit the auto industry, eventually.

Michelin Active Wheel: All-In-One Standard for Engine, Brake & Suspension

Ovidiu Sandru — Mon, 01 Dec 2008 17:42:17 +0000

The active wheel features an electric motor, a braking and an electric suspension system, which is something only seen in the military about two years ago. The electric suspension is basically the same with a classic one, except the central shock absorbers, that comprise active, step-by-step motors driving a rack-and-pinion system at each wheel, that can cancel out anything the computer tells them to.
