Given a DC motor with a wound rotor (armature) and commutator, and a non-rotating fixed field from a permanent magnet, an armature resistance of R, an applied armature voltage of V, and a no load speed of S, then as a first approximation how does speed change with mechanical load?
A separate question --- if the armature is driven at a speed S, then how does no load armature voltage relate to speed?
These are thinking questions for those that do not know the answers. Early experimenters in the electrical field had to figure out these questions.
