I'm building a self balancing unicycle which uses 5v and less than an amp for it's "brain" circuitry. However, I also have a 50v supply which is supplying power to a brushless motor at about 30A. The grounds of the two power supplies need to be connected (of course), but I'm worried about noise from the motor affecting the 5v circuitry.
Do I need to put a giant cap between the power and ground rails of the motor power supply? Or perhaps a giant inductor between the two?
Any help is greatly appreciated! Thank you in advance!
