Modern aircraft are slowly replacing outmoded mechanical systems with high performance electrical systems. WITTENSTEIN has developed a series of electrical motors which power the High Lift System of the A350 XWB aircraft. These high performance and light weight motors have been designed to operate flawlessly in the harsh environment of a commercial aircraft wing, near vacuum and in excess of -50°C. They are also being used in an initial application of a high voltage power system (540VDC) on a commercial aircraft, thus making electric power a viable solution for flight critical components.
