News Welsh develop new electric motor. Said to produce more G's.

Welsh car team pioneer electric dream

Jun 1 2005
icWales

Imagine an electric car that produces hardly any noise, no air pollution, and is as fast as a Ferrari.

It might become a reality in the near future, thanks to a revolutionary new motor designed by an enterprising team in Wales.

If the IMP motor meets expectations, it could usher in a new age of rapid, clean, electric transport.

As well as high performance vehicles, there are plans for a battery-powered family car with a range of hundreds of miles.

Electric cars to date have been more reminiscent of milk floats than Formula One.

It is hard not to laugh when recalling Sir Clive Sinclair's C5 electric three-wheeler, which was supposed to be the ideal urban runabout, but proved a catastrophic flop.

However the new motor being developed by IMP Ltd, a Welsh engineering company based in Neath, really could put electric vehicles in the fast lane.

The motor is revolutionary in that it contains no bulky permanent magnets.

Instead it relies on transmitting electric pulses across up to seven rotors, arranged in different phases. These are "fired up" in turn, much like the pistons of an internal combustion engine.

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.

"Size for size, we can provide 400% more torque than any type of motor currently available," says managing director John Bryant.

He is now hoping to team up with a sports car manufacturer, such as Lotus or TVR.

Theoretically an electric racing car driven by four of the motors - one for each wheel - could hold its own in Formula One.

"Electric vehicles still carry the stigma of the Sinclair," says Mr Bryant. "Forget it. This will outstrip a Ferrari."

At present, providing enough battery life is a problem. But battery technology is improving all the time, and Mr Bryant does not see it as a major obstacle.

If he finds the right automotive partner, a prototype electric car that would put a smile on Michael Schumacher's face could be ready within two years.

A Welsh motor that produces more Gs? Hopefully it makes more F's and L's, too.

OMG! Electric motor that provides more torque at low engine speeds than a gasoline engine? HOW INCREDIBLE!

Nothing new. There's a reason why modern diesel train locomotives actually use the diesel to power a generator, and then use the electricity to power direct-drive traction motors at the wheels.

Important to note, no air pollution at the vehicle, but the electrical power generation still pollutes. And it's got the range of a tricycle.

Wow, an electric family car with a range of "hundreds" of miles- then what? You charge the batteries for 16 hours?

the idea is an interesting concept, to say the least, i'm surprised nobody has done it before

it's bassically a progressive magnet gauss rifle, but instead of firing a projectile linearly it moves the projectile around an axle and accelerates the car

Electric motors have had the potential to destroy gas motors in racing for decades... the problem is *entirely* w/ the batteries. Batteries weigh too much, and can't produce power long enough to be really useful, esp. in racing.

Once battery tech gets better (or something like fuel cells replace them) then we'll see some awesome electric cars... but that's been true long before these guys developed a new electric motor.

From the title, I thought this was a joke thread. Good one.

And just about every diesel locomotive in the US has used the engine as a power source for electric motors, except for some low power industrial applications and a few German hydrolic units in the 60s. The big change has been the move towards alternating current.

except in order for that to hapen it would have to be 100 percent efficient and that's imposiblle

No. Your username becomes more appropriate now, though.

The motion could be reclaimed to help recharge the batteries. In fact, that's what regenerative braking does.

Of course it won't reclaim ALL the energy, but systems like that will help electric cars achieve better performance.

That's why I said "technically."

Although my 6 yo son has been riding his bicycle w/o training wheels since he was 4.5...

Correct. Furthermore, the electric power generation converts some sort of fuel to electricity. A great deal of the energy in this fuel is not converted to electricity, but escapes the power plant as heat. Then you have some line losses delivering the electricity to your battery charger. The battery charger also loses energy in heat, so more kilowatt hours go into the charger than go into the battery...
and last but not least, the batteries (and all the fun chemicals inside) will die, and you will have to throw them away.

Electric motors have fantastic torque. But, for the reasons above, are not currently ideal for personal transportation.

I think the guy in the article was comparing the torque of their electric motor design to other electric motors, but I could be wrong . . .

Sounds like the motor can't be used as a generator to reclaim energy. That could be a problem.
