IMP Ltd. Developing Promising New Electric Motor
by Michael Graham Richard, Gatineau, Canada on 06. 3.05
This firm from Wales is working on a motor that they claim can produce 400% more torque than a regular electric motor of the same size. No need for a transmission: "There are no gears - the motor provides enough torque at one revolution per minute to put a vehicle into motion - and it spins at up to 2,500rpm." No bulky permanent magnets either, IMP's motor works by sending electric pulses to up to seven smaller rotors arranged in different phases, "much like the pistons of an internal combustion engine." A prototype car powered by this technology could be ready within two years - these new motors could benefit electric cars, but also hybrids and fuel cell cars. Too early to get really excited about it, but still, very promising.

Old stuff. There are numerous efficient designs of electric motors. The hard part is convincing Congress the stop taking campaign contributions from oil companies.
For those who still crave the "vroom vroom" you can always digitize the sound of a dragster and run it through your car speakers.
Since there's no caption or anything for it, I'm pointing out that the color diagram of the electric motor shown, with its two permanent magnets and two-pole armature, has very little relation to the motor described in the article with "No bulky permanent magnets" other than the diagram showing (and not as clearly as it could) one way that electric power can be converted to rotary motion.
You are absolutely right Ben. That picture is just a generic electric motor diagram since I could not find any of IMP's tech.
The concept - is great and should actually work , from an electrical view its simple - in concept. However will requires a lot of engineering in the design .
The limitation to torque in an AC electric motor is related to the abiliy to continually get the phases ruplusion / attraction needed in the electromagnets coils correct. By adding heaps of parallel coils and a micro control to manage this should do the trick. This is what I believe is being done.
Simple. Get real. I see it all the time. We have a saying at work for what you have posted on the internet, but I can't repeat here due to you asking for respect on this site.
can anyone share the working concept for this motor for a science fair project? I'd be interested fopr my grandsons
project.
