Sumitomo Electric Industries (SEI) will soon be showing off a new superconducting motor that increases torque and takes your electric vehicle 13 per cent farther. If you happen to be in Sapporo, Hokkaido in Northern Japan on June 19 for the "2008 Integrated Exhibition of the Environment in Celebration of the Hokkaido Toyako Summit" (lucky you), check out this future tech encased in the lovely sedan pictured above.
The motor achieves its gains by using liquid nitrogen to lower the temperature of its high-temperature superconducting (HTS) wires to a chilly -200???. The low temperature lowers resistance to almost zero which results in a higher current with fewer turns and a lower voltage, thereby giving higher torque. Under development for a few years now, SEI has produced a 50Kw and 345 Kw version and hopes to create even more variants of the motor for applications as diverse as ships and buses. They expect they can do so within 10 years.
