A separate excited dc generator turning at 1400 r/min produces an induced voltage of 127 V. The armature resistance is 2 ohm and the machine delivers a current of 12 A. Calculate a. the terminal voltage [V] b. the heat dissipated in the armature [W] c. the braking torque exerted by the armature [N middot m] A separately excited dc generator produces a no-load voltage of 115 V.

One that has its field winding powered by a separate external DC source is referred to as a separately stimulated DC generator (like a battery).

What is Separately Excited DC Generator?

  • One that has its field winding powered by a separate external DC source is referred to as a separately stimulated DC generator (like a battery).
  • The speed of rotation of the armature and the field current both influence the generated voltage's magnitude; the stronger these two factors are, the higher the voltage created.
  • The individually excited DC generators aren't frequently used in actual application.
  • The field winding of a separately excited (S.E.) machine is connected to a different voltage source, whereas in a self excited generator, the field winding is connected across the armature terminals and supplies the exciting current.
