// diesel-electric locomotive: engine, main generator, four series dc traction motors in parallel. the controller sets
|
|
// both the engine speed and the excitation of the generator; the motors are connected from its first position.
|
|
// start the engine, raise the controller step by step: the generator voltage rises with the excitation and the speed
