In a perfect setup you would tighten the screw onto a flat cut on the
shaft. That way when the set screw marks the shaft you could still slide
on a pulley because the flat is below the shaft. (make sense). If you
mess up the shaft it it's very hard to add or remove a puller. Of course
most motor shafts don't have a flat on them.

So I would say, tighten it in the slot, thats a keyway slot BTW, that way
you don't mess up the shafts surface. If you ever want to put a pulley on
the motor you can file the keyway flat again. Make sense?
