High-Output Electric Motor For Cars

Via Slashdot, a Welsh team has designed a high-output electric motor for cars that can supposedly compete with Ferraris.
The motor is revolutionary in that it contains no bulky permanent magnets.

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.
