An increase of the volumic energy of flywheel energy storage systems promotes axial-flux machines before radial flux machines due to the shorter drive shaft. For the elimination of iron losses during no-load operation, a ceramic plate carries the machine winding whilst providing a good thermal conductivity for the cooling of the winding. The continuation of the ongoing research project aims to validate an ironless axial-flux PM synchronous machine for flywheel applications of up to 40 000 rpm. This requires a machine consisting of stator and rotor as well as an inverter for its operation. Currently, only the isolates ceramic winding carrier could be analyzed, neglecting numerous effects. From the author’s perspective, a successful operation of the axial-flux machine with a very small inductance and low losses demands a modular multi-level inverter. The project plan is therefore extended by the realization of the drive system.

由于较短的驱动轴，飞轮储能系统的体积能量增加在径向通量机之前促进了轴向升华机器。为了消除无负载操作期间的铁损耗，陶瓷板带有机器绕组，同时为绕组的冷却提供了良好的导热率。正在进行的研究项目的延续旨在验证一台无铁的轴向升级PM同步机，用于飞轮应用高达4000 rpm。这需要一台由定子和转子组成的机器以及其操作的逆变器。目前，只能分析陶瓷绕组载体，从而忽略了许多效果。从作者的角度来看，轴向升华机器的成功操作非常小，损失很小，需要模块化的多层逆变器。因此，通过实现驱动器系统来扩展项目计划。
