So that they are in sliding contact with the commutator?

With the brushes connected to the correct wires, because connecting to the wrong wires is BAD.

Eh?

In the case of a DC motor, won't the thing simply run 'sdrawkcab'?

not if you conduct the stator wires to the brushes. Sorry, I'm not huge on DC, but I know of a few ways that you can connect the motor up so that it would go boom. And with someone asking how to put brushes onto a motor you have to wonder if they know the difference.

I am unclear as to what you are asking. Motors usually have receptacles that brushes should be placed in. When they are put in, the face of the brush should fully contact the commutator or slip ring depending on if you have a DC or AC motor. If the mounts for the brushes have been removed and you are trying to figure out how they go back together your best bet would be to contact the manufacturer of the motor to find out how they go back in.
