2. Keep the cable length between the power distribution board, ESC, and battery
as short as possible. The three-phase wires from the ESC to the motor are less
important because they are AC and produce less interference.
3. Wrap the wires between the distribution board, ESC and battery and use
shielded wire.
4. Replace the distribution board and ESC with a 4-in-1 ESC as they tend to
produce less interference, probably because they have shorter cables closer to
each other and have an aluminum plate on top to help reduce interference.
5. Adding aluminum foil shielding around the ESC to motor cable may reduce AC
interference. But aluminum foil does not help reduce DC interference.
