Calculate induced generator EMF E = 4.44 f N Phi . To change three-phase EMF (convert) to line voltage vL(star)=sqrt3 E. Estimate load terminal voltage under load by: V appreciable length before they resumed an average encroachment.
Formula & Table Summary:
Calculate induced generator EMF using: \( E = 4.44 \, f \, N \, \Phi \). To convert three-phase EMF (star connection) to line voltage: \( V_L = \sqrt{3} \, E \). Estimate load terminal voltage under load by considering voltage drop in armature resistance and reactance: \( V_t = E - I_a(R_a + jX_s) \).

Frequently Asked Questions - generator voltage calculator:
How is generator voltage calculated?
Use E = 4.44 f N Φ for induced RMS EMF per coil/phase.
What is Φ in the formula?
Φ is the peak magnetic flux in webers (Wb) through one pole/coil.
How to get line voltage for three-phase?
Star: V_L = √3 × E; Delta: V_L = E.
What affects terminal voltage under load?
Armature resistance and synchronous reactance cause drops: V_t ≈ E − I_a(R_a + jX_s).
What units should I use?
f in Hz, Φ in Wb, N turns, E and V in volts (RMS).
Where does 4.44 come from?
4.44 ≈ 2π/√2, derived for sinusoidal flux converting peak to RMS for a single coil.
Can I calculate DC generator voltage this way?
No — DC generator (commutator) requires different models; E = N dΦ/dt still applies for flux change.
How to include winding turns per phase vs coil turns?
Use turns per phase (total effective turns in series per phase) for N in the formula.
Is this valid for synchronous alternators?
Yes — it gives open-circuit induced EMF; loaded behavior needs phasor analysis.
How to estimate V_t magnitude from phasor eqn?
Compute complex V_t = E − I_a(R_a + jX_s) then take its magnitude |V_t| for RMS voltage value.
