IMP Ltd. Developing Promising New Electric Motor
This firm from Wales is working on a motor that they claim can produce 400% more torque than a regular electric motor of the same size. No need for a transmission: "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." No bulky permanent magnets either, IMP's motor works by sending electric pulses to up to seven smaller rotors arranged in different phases, "much like the pistons of an internal combustion engine." A prototype car powered by this technology could be ready within two years - these new motors could benefit electric cars, but also hybrids and fuel cell cars. Too early to get really excited about it, but still, very promising.
