Experiment 1 The DC Machine ECEN In a dc machine the electrical power flowing into the armature is Pelec = VaIa 3 To the extent that losses within the machine can be ignored ie by approximating the The basic parts of the dc machine are diagrammed in Chapter 5 AC Machine Fundamentals OVERVIEW AC machines differ from dc machines by having their armature windings almost always located on the stator while their field windings are located on the rotor A set of three phase ac voltages is induced into the stator armature windings of an ac machine by the rotating magnetic field from the
