Prototype vehicle with a superconducting motor. If you plan to visit the exhibition, do not miss the car because it is quite a plain display.
Superconducting motor
Sumitomo Electric Industries Ltd prototyped an electric vehicle driven by a superconducting motor for the first time in the world.
The new electric vehicle will be showcased at 2008 Integrated Exhibition of the Environment in Celebration of the Hokkaido Toyako Summit in Sapporo, Hokkaido in Japan from June 19, 2008. The company intends to prove the feasibility of high-temperature superconductivity technology for electric vehicle motors and promote the technology to the public.
In a standard electric vehicle motor, the coil is supplied with a slightly lower current and a slightly higher voltage to reduce electric resistance. However, it is difficult to generate a higher torque with a lower current.
As no resistance is applied to the superconducting coil, it results in a higher current with fewer turns and a lower voltage, thus resulting in a higher torque. While the latest electric vehicle was prototyped based on a passenger car, the company also plans to consider utilizing the superconducting motor in larger vehicles such as buses and trucks.
A superconducting magnet can be used in both the stator and the rotator. The released photos show that there is nothing sealing the coolant piping to the rotator. Thus, it is likely that the superconducting coil itself is being used as the stator.
Super conducting motor ping!...........
Please Freep Mail me if you'd like on/off
I don’t believe there are room temperature superconductors yet, so a coolant like liquid nitrogen is needed to keep all windings superconductive.
Ok this stuff is over my head, but I was wondering if a upscale system like this could be adapted to one of super muscle tractors in those tractor pulls.
So how often do you have to go looking for a liquid helium station as the coolant boils off?
“I don’t believe there are room temperature superconductors yet, so a coolant like liquid nitrogen is needed to keep all windings superconductive.”
Ahhhh..... Regular....Premium....Diesel.....Oh, here it is... Liquid Nitrogen.
$40/gal.
$38.99 if you are paying cash.
(/sarc)
Couldn’t they have put it in a car that’s a little less plain?
I guess they wanted to show off the motor, not the car.......
Interesting!
We have had room temperature superconductors since April 22 1995, just a few days after the OKC Bombing (which may have hidden it from your radar. During the war in the former Yugoslavia Clintoon shut down the Yugoslav power grids with superconductor shard bombs.
If congress were really serious about ending foreign fuel dependence, replacing the backbone of the power grid would be at the top of the list.
WHY have American companies, so completely ceded technological leadership to foreign companies?
America sent Apollo to the moon.
Not Japan.
Yet, American companies are LOST in the current environment.
What??? Happened???
Feb 1987 YBCO discovered to have Tc of 90 K by Paul Chu et al.
1988 BSCCO discovered with Tc up to 107 K, and TBCCO (T=thallium) discovered to have Tc of 125 K.
As of 2006, the highest-temperature superconductor (at ambient pressure) is mercury thallium barium calcium copper oxide (Hg12Tl3Ba30Ca30Cu45O125), at 138 K[4] 138 K, is held by a cuprate-perovskite material,[5] , possibly 164 K under high pressure[6].
March 2008 Tc of about 185 K claimed for (Sn1.0Pb0.5In0.5) Ba4Tm5Cu7O20+ [7]
The freezing point of water is 273 K. High temperature superconductors are also limited in how strong a magnetic field they can be immersed in before they lose their superconductivity.
What??? Happened???
They moved overseas............
