Hey, this is a little outside of the great feedback you are already getting, but have you reached out to an electric motor shop? Greenville has a fantastic shop that can repair or replace any motor on any machine. I have been using them for service since I moved here in 2000. They recently repaired a Dewalt miter saw for me, that an authorized Dewalt service center told me was trash. The motor shop replaced the armature bearings, polished the windings, soldered in new connections between the switch and the motor, and they even changed the arbor bearings for me while they had it apart. The bill was $116 and it was ready in 3 days.
Last year, I had a 10hp motor go out on a 26" Wadkin bandsaw. They put a new WEG industrial grade, constant duty, 10HP motor on it for $1,600.
I ALWAYS check with them before I do anything else.
