What is the EMF equation of alternator?

EMF equation of DC GeneratorE = (ΦNPZ) / (60 * A)

where,

E = e.m.f induced in any parallel path in armature

Φ = flux per pole in weber

N = armature rotation in revolutions per minute (r.p.m)

P = No.of generator poles

Z = total number of armature conductors

A = No.of parallel paths in armature
