Project Details


Usually, the cooling cycle is designed for the transportation of losses generated from the electrical machine. Nowadays, the integration of various components leads to drive systems, which do not need much space. As a consequence of the very compact system, the thermal coupling between the used parts is very strong. Thus, big thermal power sources situated beside the electrical machine could have the ability to deliver a to high heat flow rate towards the designed cooling cycle of the electrical drive. Thermal overheating within the coil domains will be the result. Thus, a more global view of the problem must be developed in order to use synergetic effects due to the cooling of different parts, the electrical machine, and the undesired heat source. Thereby, the construction takes use of additionally introduced cooling channels and thermal isolating areas, which have the ability to avoid limiting material temperatures within the total system. Moreover, an optimized total cooling system could be established, which has from an energetic point of view better properties as the primary separated cooling systems had.
