Electric Cars as Fast as Ferraris

samzenpus posted more than 8 years ago | from the how-many-batteries dept.

Technology 739

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."

jdbear (607709) | more than 8 years ago | (#12703194)

They don't need to close it down. The problem with electric cars is not now and has never been the motor. The problem is the energy per pound (or per kilogram for anyone outside the US) that our current crop of batteries can deliver. The new Lithium Ion batteries from Altair and Toshiba [slashdot.org] should fix that.

jacquesm (154384) | more than 8 years ago | (#12703219)

they've got nothing to worry about from this one.


One disadvantage of this motor compared with PM motors is that it runs pretty high revs to make it's maximum power which implies gearing of some sort.


If this thing works in reverse it would be a nice basis for a windmill with electronic braking though ! As soon as you hit your target RPM you start firing the motor in the opposite direction.

Just because you don't see it doesn't mean it doesn't happen. Albeit, motorcycles seem to be for those who really want to break the speed limit, but cars do as well. You don't see this because if the driver is prudent, they will slow down if they see any oncoming traffic (possible unmarked police car). It is usually the idiot teenagers who drive their shitty cars way too fast (yesterday, a guy at my high school rolled his jeep because, it seems, he was going 80km/h in the parking lot).

Analogy Man (601298) | more than 8 years ago | (#12703213)

Actually, when GM came out with their electric vehicle (I worked at Saturn in the same building as the EV1 team)...my thought was the way to dispell the perception that this was some "granola eating tree hugger technology" they should start a racing circuit. They could hit the off season in unconventional venues, (e.g. the now unused Silver Dome). If you had cars going 120mph indoors it would look fast.

nharmon (97591) | more than 8 years ago | (#12703108)

The path to pure electric cars is not in making more powerful motors, but in improving battery technology. Thats not to say that the concept here is not impressive, it is. However, running four of these motors (one for each wheel) is going to draw some SERIOUS juice.

Re:As always (1)

lostwanderer147 (829316) | more than 8 years ago | (#12703188)

FTA: the motor provides enough torque at one revolution per minute to put a vehicle into motion - and it spins at up to 2,500rpm. That's a lot of freaking torque. "Serious juice" is an understatement. I'm not really sure exactly how much, but I'm sure that even one of these things would take more power than currently available in most electric car batteries. To run four of them at once, not just at once, but in sync, you'd probably have to hook it up to more power than would be worthwhile to use: you'd either have so much weight from batteries, or it would have to have a really long power cord.

Re:As always (1)

jasen666 (88727) | more than 8 years ago | (#12703209)

They only mentioned 4 motors for Formula One racing. I'd assume a street car would be outfitted with just one. Current electric cars have only one motor, and they claim that this one is more powerful than those.

Do you not know what Stall Torque is? That's the torque rating where a motor doesn't turn anymore.

Whaaaaaaa? There is no such thing as "infinite torque."
Electric motors produce their maximum torque at 0 rpm. And this amount of torque depends on the size of the motor, the current, etc.

Bloater (12932) | more than 8 years ago | (#12703192)

Ever tried to start a regular domestic car (manual) without using the clutch (IE, put it in first, lift the clutch, then turn the key in the ignition). It won't happen. Internal combustion engines have so little torque at 0 RPM that it isn't funny.

That is what the clutch is for. It lets you get the RPM of the engine up before it has to apply torque.

Re:Torque (1)

tankd0g (875636) | more than 8 years ago | (#12703185)

Electric motors are already producing their maximum torque at 1 RPM. That's why electric sports cars are capable of blistering 0-60 times even if they usually can't go much faster than 60 once they get there :)

Re:Torque (1)

kfg (145172) | more than 8 years ago | (#12703229)

No, it's not. They all do that. Check out any electric car already on the road, or any large scale electric R/C car if it comes to that. No tranny. No need. Maximum torque at 0 rpm.

They also seem to have "invented" a brushless DC motor that we've been using for years and is already available off the shelf. The R/C plane people in particular, where every ounce is critical, love these things. It's the microchip that made them practical by timing the phase shifts.

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.

How about a car which:

  • refueles itself when it is left out in the sun
  • Uses absolutely no energy when stopped in heavy traffic
  • Can be used in remote areas without expensive infrastructure for fuel
  • Is so simple it could last as long as a washing machine without significant maintenance

Part of the problem is that the people who promote electric cars are the kind of people who couldn't market any kind of car at all. Their products tend to look like glorified electric wheelchairs, and about as usefull.

I want to see advocates of electric power push the advantages of the technology, not reasons why we should put up with its limitations.

Yea yea....battery technology is improving all the time. Remember when Li Ion batteries were "memory free"?

I'm sure many of you will be quick to interject the "latest and greatest" battery tech but, at this point, I'll believe it when I see it.

Very clever, using multiple rotors and phases like that.

While running fast is great, and probably essential for mind-share, I wonder about power consumption. A 1:1 gear ratio seems a little short.

I forget the details about electric motors. Doesn't power consumption increase with RPM, and so wouldn't a transmission help increase efficiency?

Efficiency, leading to low power consumption, is the key for an electric passenger vehicle.

Its not hard to make most cars as fast as a Ferrari, Porsche or other neo-exotic. If you think speed is the reason behind them, you have a) never been in one, b) never driven one and c) just don't get it.

Considering there's a big electric drag race scene, speed isn't something thats an issue with electrics. Batteries is.

You have no idea how difficult and expensive it is to make (develop and produce) a V12 or V16 engine. Yes, going as fast as a ferrari is hard.

Put a gas engine on board and hook it to a generator. Output the generator to the electric motor. For 400% more torque, why not? It'd still have a target audience.

Me, I'm worried about different things. That's a lotta current in square waves being fed into coils. Mucho RF interference. Better bring your MP3 player because your radio isn't going to work very well.

"As fast as a Ferrrai" (0)

Anonymous Coward | more than 8 years ago | (#12703191)

"As fast as a Ferrari" is rather vague. Which one? You can buy a modern family sedan faster than many older Ferraris.

It sounds like the only advantage here is that the electric motors will be lighter and smaller, since they don't use large permanent magnets. They could be more powerful, but that would require more...power. Which brings us to the major limitation of electric powered cars, batteries. Which add much more to the weight of a car than the electric motor. So performance like a modern Ferrari in ways other than acceleration is still not going to happen, no matter how fast it is.

stevev007 (887227) | more than 8 years ago | (#12703193)

I think seriously, that the Ferrari and performance cars like it will be around for a while to come. The alure of these cars is not gone in my opinion, even though they have long been surpassed in speed and acceleration. I don't know how many /.ers have been behind the wheel of a Ferrari, but I would still love to drive one if and equivalent electric counterpart was produced.

That being said, maybe Ferrari will pick up this technology, seriously. They always seem to be inovative to push their cars up to the next notch of performance. And maybe, just maybe, if implemented just right, this will finally remove the stigma of a temperamental Ferrari.

Wow. . . (1)

At this rate, three and four-hundred mph cars will be just over the horizon.

Literally, because that only as far as current battery technology will take them.

Gas turbines have this beat (4, Informative)

G4from128k (686170) | more than 8 years ago | (#12703199)

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.

Brushless motors... (1)

bopo_the_mofo (888877) | more than 8 years ago | (#12703201)

...aren't exactly a new idea, are they? We've been using them for years in RC models, for example. I'm pretty sure that they work as described in the article: a series of pulses go sequentially to the coils arranged around the motor. Sure, they're expensive, but they're soooo fast and efficient. Sounds like these guys have just made a bigger one and are looking for some publicity...

Upgrade the grid (1)

FidelCatsro (861135) | more than 8 years ago | (#12703217)

When Electric cars become commen place , the national grids i imagine will need to have a serious overhaul due to the added requierments for extra power .
If we dont move away from fuel sources such coal gas oil etc then we may have just as much poloution albeit more centralised .
I will have to check into that , but i imagine charging up a battery for one of these things will seriously hike the electricity bill /requierment

They had a car on techtv about 3 years ago now made by an american car company that is FASTER than a ferrari and can easily beat the ferrari off the line because its lighter. Its an amazing car and I am sure you can find it by googling electric super car.

No permanent magnets (1)

ajs318 (655362) | more than 8 years ago | (#12703238)

A motor without bulky permanent magnets? Like your car's starter motor, you mean? Like the AC/DC brush motors used in sewing machines, vacuum cleaners, electric drills and so forth? {Clocks obviously use synchronous motors; electric fans and central heating pumps use induction motors, but a lot of appliances still do use brush motors.} None of these motors need permanent magnets, they use an electromagnet polarised by the power source. And since the armature and stator magnets reverse their polarities together with the power supply, the motor will turn the same direction whichever way around you connect the power leads, or even on an alternating current supply.

Or what about like a variable-reluctance stepper motor, where the steel armature lines itself up between the energised coils on the stator? That's the principle I'm betting on it using ..... all the electromagnets are standing still, obviating the need for any brushes, you can switch them electronically with great big chunky FETs; the switching rate determines the speed of rotation, and the duty cycle determines the maximum available torque.

Come back when you've invented something that nobody has invented before. Then it'd be news.

Electric car speed record (1)

grqb (410789) | more than 8 years ago | (#12703239)

A few weeks ago there was a British team that wanted to break the electric car speed record [thewatt.com] (by driving 252 mph over a distance of at least 1 kilometer). They said that a geared car can achieve 100 mph in a few seconds but their rate of acceleration falls away much more quickly compared to the acceleration of this electric car that can accelerate past the 300 mph mark. Also, electric vehicles have, theoretically at least, infinite torque (at 0 velocity).

polysylabic psudonym (820466) | more than 8 years ago | (#12703240)

I just RTFA and it's a news report. Absolutely useless. I want to know if this is a useful motor. I want to know how much power it draws, I want to know how much power it delivers at a reasonable driving speed, eg 100km/h (60 mph).

Tzero...pick any two (1)

evenprime (324363) | more than 8 years ago | (#12703255)

Electric cars currently can be Fast enough, go far enough, or be cheap enough for normal people to use. The problem is that it looks like you have to pick two of the three, and normal people want all three. FWIW, the tzero is an electric car that already exists that is as fast (in 1/8 mile drags strip tests) as a ferrari. It also has a decent range...the designers were able to drive from cali to vegas for the SEMA show on a single charge of the lithium ion battery pack.

The problem is that it costs as much as a house. http://www.acpropulsion.com/tzero_pages/tzero_home .htm

Toyota hybrid news? (4, Interesting)

islandrain (888578) | more than 8 years ago | (#12703262)

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.
