Separately Excited Dc Generator Pdf. Types working construction applications. A dc generator whose field winding or coil is energised by a separate or external dc source is called a separately excited dc generator.
Or it can come from the generator s own output in which case the generator is called a self excited generator. But in the saturated region. Electrical power and machines department dc systems sheet 1 dc generators 1 a separately excited generator has a field resistance of 100 ω and armature resistance of 1ω and motor constant k 0 5 v a rad sec if the field voltage is 200v and load current is 10a while the driving speed is1500 rpm find.
If the armature reaction is neglected decrease in v a should be linear and equal to the voltage drop across r a and carbon brushes.
Short compound self excited generators. The flux produced by the poles depends upon the field current with the unsaturated region of magnetic material of the poles. Short compound self excited generators. Separately excited dc machine.
