Fraunhofer Institute for Integrated Systems and Device Technology IISBThe ability to transfer power in small moving systems is required for a wide range of applications such as wind power systems with electronics integrated in the rotor blades or highly-automated Industry 4.0 production platforms. The goal of the project is to develop a technology for the contactless transfer of power and data in small moving components in harsh environments.
Inductive Ball-Bearing
Project Targets
Realization of an inductive energy transfer for fast moving components
Transmission power up to 20W
Wireless communication of information as well as higher data rates for the transmission of sensor & actuator information
Challanges
High integration level of the coupling coils
Realization of a rotating transformer with metal parts in the surrounding
High mechanical conditions
Results
Demonstration of the functionality of the rotating application (ball-bearing with shaft)
Practical robustness tests & simulations of electronic assemblies beyond the normative measuring range
Near field transmission at high frequencies including alternative capacitive transmission systems with differential directional coupler
High-quality digital modulation and thermoelectric optimization of the crossover
Project Partners
Research project in cooperation with the Chair of Electron Devices LEB) and further chairs of the Universität Erlangen-Nürnberg
