I have a small Emax RS2205 2600kv 16v DC Motor that is turning a PCB with IC chips that needs to be powered.
I want to send 2 power cable (VCC and GND) from to stationary battery to the rotating PCB.
Here's what I am trying to build:
I can't use slip ring because of the engine will be hitting some high RPM. Though if you are aware of a miniature high RPM (2000+) 2 channel 5v slip ring please recommend.
I couldn't find brushless slternators, nor rotary transformer that are small in size that can pass 5v either.
What is the best miniature lightweight solution for transferring power for such system?
