Modelling and optimisation of power losses in electrical drives and their thermal coupling with machine tools (C04+)

点击翻译按钮获取中文摘要

C04 develops a targeted loss control of the drive motors to be used as heat managers to influence the heat flows into the machine structure, without thermal overloads as well as impermissible speed or torque fluctuations occur. In addition, a multiphysics motor simulation in combination with a state estimator allows the early detection of parameter deviations and errors. Furthermore, in cooperation with C02, the effectiveness of thermal absorbers based on phase change materials to stabilize the heat flows in electric motors is universally predicted and experimentally confirmed. Finally, the improvement potential of new additive manu-facturing technologies and new materials for the internal thermal resistances of the motors is estimated.
