Bruno Lequesne
Biography
The patented work of Bruno Lequesne has driven advances leading to the realization of “more electric automobiles” that use electrical and electromechanical systems for improved fuel economy, reduced greenhouse emissions, and better safety. With innovations recognized by multiple awards from industry leaders such as Delphi and General Motors, Lequesne’s work on linear actuators provided closed form solutions to identify the best configurations for engine-valve motion or suspension. His work on encoders for brushless motors helped overcome torque ripple in electric power steering systems, contributing to a fuel-saving feature now standard in most vehicles. His camshaft and crankshaft position sensors for engine control help to reduce emissions, and his wheel speed sensors for anti-skid braking have made vehicles safer. He also developed one of the first induction belt-driven starter generators, which has enabled start-stop functionality to help eliminate idling losses in engines.
An IEEE Fellow, Lequesne is president of E-Motors Consulting, LLC, Menomonee Falls, WI, USA.
