This is probably the best solution. I doubt that there is a bolt in low voltage motor replacement for this application. Lassen Forge's solution eliminates the need for transformers, VFDs, high voltage and other nonsense.
I use Molykote Gn on enclosed pressure screws. Extreme pressure grease will also work. For exposed screws, I use Dupont Chain-Saver. It's a wax lubricant, with teflon. This also works well on the sliding parts.
