Hello,

I have some ICs that I want to send power to, though they are attached to the rotor of an EMAX brushless motor.

The engine can hit a few thousand RPMs, making slip rings a none ideal solution, not to mention quite large for such a small project.

Any ideas how I can send power to them?

Thank you

Brushless alternators have a static field which generates AC in a rotating winding. A rectifier is then used to provide the excitation to the main part of the alternator.

If you are going to use high speeds, then you will need to take into acount centrifugal forces. Look how a car alternator manages this.
