Sonja Lundmark

Associate Professor at Electric Power Engineering

Sonja Tidblad Lundmark focuses her research on the design of electric machines and drives primarily in the application of traction vehicles and wind power generator systems. Specific targets are towards low cost, low weight, efficient, recyclable and fault tolerant drives. The purpose is to contribute to the development of making electric and plug-in-hybrid vehicles more competitive as well as to contribute to the success of sea-based wind power stations.

Sonja is active in the Swedish Electromobility Centre within the Electric Drive System group.
