Problems on dc generators
WebbLosses in DC Generator The input power is not fully transformed into the output power in a DC machine. Some part of input power gets wasted in various forms. In a DC machine, the losses are broadly classified into … Webb20 aug. 2024 · ( 1) It is clear from eqn. (1), that for any dc generator Z, P and A are constant so that E g ∝ N ϕ. Therefore, for a given DC generator, the induced EMF in the armature is directly proportional to the flux per pole and speed of rotation. Case 1 – For Lap winding, number of parallel paths A = P. Thus, E g = φ 𝑁 𝑍 60 … ( 2)
