Hello,
I try to find solution for my project. Qi-compliance is not required.
Power has to be provided to rotating element (RX side). On TX side I will have motor which shaft will rotate RX part. This is why I need TX and RX coils with at least 8 mm hole in the middle for the shaft, coils should be around this shaft (RX coil will rotate above fixed TX). Do you know such a solution which could provide at least 3W (@ 5V best).
Best regards
Daniel
