Or you could try the bucket solution. (twice in, once out)
On a more helpful vein...Remember it's the controller not the motor itself,
although the motor may be acting as the radiator, along with the mains
wiring. Try and keep filters as close to the controller as possible.
Check to make sure the chassis ground is still tight. More turns around
the same core are way better than more cores. Different core materials
tend to be better at different parts of the spectrum.
It's unlikely one thing will fix, so be prepared for multiple passes.
