Inside pics of a 3040 300w DC spindle motor

[Musht]

Finally cooked original spindle on my 3040, it only ever cuts ply, insulation foam and its nemesis, Tufnol.

Think got overambitious with tool size and depth of cut in black tufnol , though it seemed OK with brown tufnol. Whats the difference between brown and black phenolic?

Bearings have ,er, a bit of slop. Most of the brushes appears to have fallen into the nose bearing. Though going by the tracks the spindle had a hard life as a servo core before it became a spindle on a 3040.

FYI its 54mm diameter , replacement spindles on ebay are 52mm and need new spindle mount, 70 X 20 mm spacing on the mount.
