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

C04开发了一种有针对性的损耗控制驱动电机，用作热管理器，以影响进入机器结构的热流，而不会发生热过载以及不允许的速度或扭矩波动。此外，多物理场电机仿真与状态估计器相结合，可以早期检测参数偏差和误差。此外，在与二氧化碳的合作中，相变材料吸热器对稳定电机热流的有效性得到了普遍的预测和实验证实。最后，展望了新型增材制造技术和新材料对电机内热阻的改进潜力。

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.
