Question 13: Below is an electromechanical speed-control system. The dc motor voltage v₂ is supplied by a generator driven by an engine. This is useful especially for diesel locomotives to operate at an efficient speed. The efficiency of the electric motor is not as sensitive to speed and thus can be used to drive the locomotive at various speeds. The motor voltage v₂ is varied by changing the generator input voltage v₁. The voltage v₂ is related to the generator field current lf by va = KfIf. a.
