Currently building a spindle out of some scrap aluminum and old angular contact bearings (NSK 5205zz). really just taking my time and having fun with it. What I'm trying to figure out is the best way to control an old dc motor that I found in the scrap hopper. Baldor 3440 frame 56C 3/4hp. 90v 7.6amp. this thing is very large. Any suggestions would be greatly appreciated.
