    Ok.... Maybe I'm the idiot here...

    But why does the wire wheel need to spin? It's a lathe. The part spins. Mount a brush like this (obviously choose the correct wire size and brush size) https://www.mscdirect.com/product/details/75846162 radially, spin the part, move the brush along the part.

    What am I missing?

    Could try the static brush idea couldn't hurt.

    Also, another wacky idea, how about get a little planetary gearbox. There are lots of them on ebay for using as stepper gearboxes. Mount a rubber drive wheel on one end and a wire brush on the other. contact the rubber wheel to the spinning part to drive it.

    The air motors do also... The gas in use (air) expands when it goes from compression at 90-120 psi to atmo.
