Electrification of the power train will play a key role in the struggle for higher energy efficiencies and reduced emissions of vehicles. Optimized control of modern electric motors requires precise measurement of the rotor position. Electricfil has developed an Electric Motor Position Sensor (EMPOS) that provides a number of advantages over traditional sensors, including very high robustness to mechanical tolerances, a digital interface and low production costs [1]. After having validated the concept on prototypes, EFI Automotive is now working on the industrialisation of the product that will be ready for mass production scheduled to begin in early 2015.
