Back EMF for DC Shunt Generator Solution

STEP 0: Pre-Calculation Summary
Formula Used
Back EMF = Machine Constant*Magnetic Flux*Angular Speed
Eb = Kf*Φ*ωs
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
Angular Speed: 270 Revolution per Minute --> 28.2743338808683 Radian per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Eb = Kf*Φ*ωs --> 2*0.2*28.2743338808683
Evaluating ... ...
Eb = 11.3097335523473
STEP 3: Convert Result to Output's Unit
11.3097335523473 Volt --> No Conversion Required
FINAL ANSWER
11.3097335523473 11.30973 Volt <-- Back EMF
(Calculation completed in 00.020 seconds)
