D.C Generator E.M.F Equation

E.M.F Equation

Derive the emf equation of a DC generator.

E= dΦ/dt = ZΦN/60 x P/A Volt
Where, Φ = flux/pole in wb; Z = total number of armature conductors = No.of slots x No.of conductors/slot; P = No.of generator poles; A = No.of parallel paths in armature; N = armature rotation in revolutions per; minute (RPM); E = e.m.f induced in any parallel path in armature
