The heat and cooling of electronically switching synchronous machine as a main drive of a car

The electromobil or hybrid-electromobil is equipped by an electric machine. This machine can work in a generator mode or in a motor mode. Because the size and weight of this type of machine are very limited, it is necessary (during the drive) to overload this machine for a short time. Consequently, the cooling system, the winding insulation system and power losses as dependent on temperature are very significant. This paper summarizes the one-year work on this type of machine. The process of designing this machine is to be continued.
