One of the issues that LitSpin raises is power transmission between moving and static parts. One idea that came to mind was induction but we didn’t know whether integrated solutions existed and if they did, would they work with our power requirements.
Würth Elektronik offers a plug and play development kit that allows for 200W of output power which solves our power transmission issues.
Since the coils work using resonent induction, W.E. integrated frequency modulation in order to allow I²C data transmission. This could allows us to put the wifi module on a static PCB and get rid of the signal drops that were present on previous projects with spinning wifi modules.
The rotating assembly would become completely wireless while avoiding the issues that rotation at a relatively high speed (for the size of the system) can create.
