Kinetic energy storage and fast-rotating machines

Over the past 5 years of research, a number of publications on FESS have been published. Furthermore, two working prototypes of kinetic energy storage devices for mobile applications have been developed, built and commissioned in cooperation with industrial partners:

CMO – Clean motion offensive

TSA – High Fly

FESS are not only suitable for mobile applications. The basic conditions regarding weight, self-discharge, energy content and energy density are fundamentally different from those of mobile applications. The realization of a stationary energy buffer for solar power in single-family homes is currently being dealt with as part of a research project. Self-discharge to preserve the energy overnight is of fundamental importance. Technically this is shown by the self-discharge testbed

Another research focus is the storage of fast-rotating systems, which has emerged as a critical component. Ongoing research deals with different aspects of rolling bearing systems. This includes, among others:

• Bearing life increase by passive and active methods

• Loss moment minimization to reduce self-discharge

• Quantification of the thermal conductivity of rolling bearings

• Optimization of the lubrication situation
