Electric Cars as Fast as Ferraris
Ubergrunt writes "A Welsh engineering company has made a motor to be used on electric cars that will make them as fast as a Ferrari. "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."

<kritical> matts: bikes go faster than cars...a bike at 60 mph is a lot faster than a car at 60 mph
<matts> kritical: um no...
<kritical> matts: um yes
<kritical> my sisters sport car at 60 mph goes faster than my dads explorer at 60 mph
<kritical> a bike at 60 mph will blow by a car at 60 mph
We recently had heard in the office over one of the Yellow Machine that's made by Anthology Solutions.
Vehicle detectors at intersections use induction to count vehicles. If you stop on one you could theoretically use inductive coupling to charge your battery, at the expense of the government.
I have seen plans for charging up battery and flywheel powered vehicles in this manner, but with more powerfull inductors.

The High Pressure Fuel Turbopump on the space shuttle has this power-to-weight ratio beat by a mile. The two-stage, eleven-inch diameter by 3 foot long turbine delivers 75,000 horsepower and weighs about 775 pounds. That works out to 100 hp per pound.
Of course, you need a supply of liquid hydrogen and oxygen to run the beastie, but if your really need the power, this is the way to get it.
If LH2 and LOX are too exotic, then try a helicopter gas-turbine. A 600 pound gas turbine can easily provide 5,000 hp.
The counter-argument is that a gas turbine needs a serious transmission, which adds to the weight of the unit. The counter-counter-argument is that these electric motors need batteries or a motor-gen set which also adds (arguably more) weight to the vehicle.
Two wrongs don't make a right, but three lefts do.
Did you hear about the Toyota hybrid recall that kept stalling because its internal computer didn't know when to switch from electric to gas? Over 33 of them have been found at fault but almost 44,000 have been sold this year. That's not a recall, Ford is the king of recalls. Engine stalling vs. car blowing up. Your call.
Peace out, homies.
Insightful? WTF? I think we need a "-1, tinfoil hat club" modifer. Either this is an idiotic comment, or it's an attempt to be funny that kind of fell flat.
WHY would the car industry want to shut this down? EVERY SINGLE MAJOR CAR MAKER IS BUILDING ELECTRICS as we speak, and most have something on the market at the moment. So far, hybrids that are only somewhat more fuel-efficient than pure gas engines have been a necessary concession, mostly because of performance, range, and infrastructure (fueling) issues.
If this technology gets off the drawing board and actually works, the car makers will shit themselves to get their hands on licenses because this seems to solve the performance issues, hands down. They'll still have to cope with range and fueling problems, but those have their own solutions coming, sometime.
And what, exactly, do you expect the oil industry to do to "close this down"? Where on earth would they get the power to do something like that, in a country like the UK?
Look, oil producers realize that hyper-aggravated prices don't help them, in the long run. That's why OPEC is struggling right now to increase the world supply by upping production, with mixed results. Big Oil wants a stable price, and not too high, either, because it makes the market nervous and causes people to buy less oil in the long run! (It's more complicated than that, but basically that's the story with any commodity.)
But their inability to increase the supply to meet the higher demand, thereby lowering the price of oil, shows that they CAN'T increase supplies much more. They would probably breathe a sigh of relief if production could go up (which it probably never will), so the only credible scenario to decreasing prices is to decrease demand.
Big Oil would benefit, in the long run, from a demand for oil that slacks off a bit and then stabilizes (below its current level) for the future. They know this, and aren't going to stand in the way of anything that keeps it from happening.
Sure, a higher power/weight electric engine capable of operation over a wide spectre of speeds is useful. It is not, however, the thing an electric car needs the most to be competitive.
It's *already* the case that an electric motor is equally strong, or stronger, than a equally heavy internal combustion engine.
The problem for electric motors is *energy*storage*, typically batteries. With todays tech 400kgs of batteries can store *maybe* a tenth of the energy in a tank of petrol weighing a tent of that, meaning it's 100 times less effective for storing energy.
To add insult to injusry the 40kg petrol-tank can trivially be refilled in a minute or two, while the battery-pack weighing ten times as much and storing a tenth of the energy, needs hours at best to approach full.
Nice try. Am I right in assuming that you've never worked on a car engine? Hint: They don't have any internal gearing at all. That's what the transmission is for. The article is clearly discussing a direct drive setup with enough torque to drive the wheels without any sort of transimssion.
which means 4 transmitions
Did you RTFA? These motors are designed to be hooked directly up to the wheel. That means that this engine doesn't NEED any transmission because it generates enough torque at 0 RPM to move the vehicle, and can rotate fast enough to propel the vehicle at all speeds.
And electric motors, properly built, are very very tough.
