## EMF For DC Generator Solution

STEP 0: Pre-Calculation Summary
Formula Used
electromotive_force = Flux per Number of pole*Number of pole*Motor Speed*Number of conductors/60*Number of parallel paths
ε = F*P*N*Z/60*A
This formula uses 5 Variables
Variables Used
Flux per pole - The flux per pole is the ratio of flux by poles. (Measured in Weber)
Number of pole- The number of pole is properties of the transfer function, and therefore of the diﬀerential equation describing the input-output system dynamics.
Motor Speed - Motor Speed is the speed of the rotor(motor). (Measured in Meter per Second)
Number of conductors- The number of conductors is the variable we use for getting the correct number of conductors.
Number of parallel paths- The number of parallel paths in a DC machine depends on the type of armature winding used.
STEP 1: Convert Input(s) to Base Unit
Flux per pole: 10 Weber --> 10 Weber No Conversion Required
