Carbon Nanotube Yarns Could Replace Copper Windings in Electric Motors

Motors and motor driven systems account for between 43 percent and 46 percent of all global electricity consumption; a staggering fact to say the least.

Needless to say, researchers feel that if electric motors could be made to run more efficiently, energy consumption would inevitably fall.

Research conducted by Rice University in 2011 demonstrated that carbon nanotubes braided into wires could outperform copper in conducting electricity, allowing for a first step towards a new way of thinking: a way to create those improved efficiencies.

Building on that research, a team at the Lappeenranta University of Technology (LUT) in Finland has replaced the copper windings used to conduct electricity in electric motors with a woven material made from threads of carbon nanotubes and achieved remarkable new efficiencies in the motors.
