Back EMF for DC Shunt Generator Solution

STEP 0: Pre-Calculation Summary

Formula Used

Back EMF = Machine Constant*Magnetic Flux*Angular Speed
E_b = K_f*Φ*ω_s
This formula uses 4 Variables

Variables Used

Back EMF - (Measured in Volt) - Back EMF is developed when current flows through the armature, it generates a magnetic field that interacts with the field produced by the field winding to produce a torque.
Machine Constant - Machine Constant refers to the parameter which usually has a constant value for a particular type of dc machine.
Magnetic Flux - (Measured in Weber) - Magnetic flux (Φ) is the number of magnetic field lines passing through the magnetic core of an electrical dc motor. It is a measurement of the total magnetic field which passes through a given area.
Angular Speed - (Measured in Radian per Second) - Angular speed is the rate of rotation about an axis, measuring how the angle changes with time. It is measured in radian/sec.

STEP 1: Convert Input(s) to Base Unit

Machine Constant: 2 --> No Conversion Required
Magnetic Flux: 0.2 Weber --> 0.2 Weber No Conversion Required
