In high-speed applications the operation temperature is in focus as high specific power is required. Thereby, heat transfer phenomena in all components is optimized to the best level. WP 3 focuses on energy and material efficient high-speed drive systems. These are required in several industrial and mobile applications. Heat transfer and optimised performance of the electric devises are investigated in WP 4 as high specific power is required especialy in mobile applications like aviation, trains and off-road machines. An important aspect in industrial and economics is deeply studied in WP5 sustainability of high-speed drives.
In all these WPs we take into account that industrial and mobile applications may differ significantly from each other as shown in Figure below. Industrial applications need before all reliability, high efficiency and maintainability while mobile applications require high specific power.
