The motor armature is made up of the windings and commutator, mounted on the motor shaft, which is supported by bearings. The armature is located so the windings are within the permanent magnet, and the commutator remains exposed for contact with the motor brushes.

Outside of a tiny drop of oil for the bearings, and possibly cleaning the carbon from the grooves of the commutator, there is little to be done.
