E = (Nr*Φp*Z)/60
This formula uses 4 Variables
Variables Used
EMF - (Measured in Volt) - EMF is defined as the electro motive force which is needed to move the electrons within an electrical conductor to generate flow of current through the conductor.
Rotor Speed - (Measured in Revolution per Minute) - Rotor speed refers to the speed of rotation of the armature. The armature is the part of the generator where electrical energy is produced by electromagnetic induction.
Flux per Pole - (Measured in Weber) - Flux per Pole refers to the amount of magnetic flux produced by each individual pole of the generator field winding. It is an important parameter and affects the output voltage.
Number of Conductor - Number of Conductor refers to the total count of conductors present in the armature of a dc generator.
STEP 1: Convert Input(s) to Base Unit
Rotor Speed: 1200 Revolution per Minute --> 1200 Revolution per Minute No Conversion Required

What is EMF ?

Electromotive force (EMF) is equal to the terminal potential difference when no current flows. EMF and terminal potential difference (V) are both measured in volts, however they are not the same thing. EMF (ϵ) is the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through.
