When I made my dV/dt filter I had a similar problem when I had capacitors as well as inductors. Inductors alone work fine for reducing motor noise and increasing general smoothness.

The capacitors need to be sized correctly. They are called snubber capacitors.

There's plenty of information here to design what you need. Make sure you look for the sections that are for the L-C subbing circuit. The last one at section 3.3 calculates it out, and in the following section calculates against power usage. A little thought of source for higher power inductors is audio, iron laminated cored inductors.
