Machine Construction Constant of DC Shunt Motor given Angular Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Constant of Machine Construction = Back EMF/(Magnetic Flux*Angular Speed)
K_f = E_b/(Φ*ω_s)
This formula uses 4 Variables

Variables Used

Constant of Machine Construction - Constant of Machine construction is a constant term which is calculated separately to a make calculation less complex.
Back EMF - (Measured in Volt) - The Back emf opposes the current which causes it in any dc machine. Back emf refers to the voltage that is generated in an inductor or a coil of wire when the current flowing through it changes.
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.
Angular Speed - (Measured in Radian per Second) - Angular speed refers to the rate at which an object rotates around an axis. In the context of a DC (direct current) motor, angular speed represents how fast the motor's rotor is spinning.

STEP 1: Convert Input(s) to Base Unit

Back EMF: 231 Volt --> 231 Volt No Conversion Required
Magnetic Flux: 0.114 Weber --> 0.114 Weber No Conversion Required
Angular Speed: 161 Revolution per Second --> 1011.5928344044 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_f = E_b/(Φ*ω_s) --> 231/(0.114*1011.5928344044)

Evaluating ... ...

K_f = 2.00309424954233

STEP 3: Convert Result to Output's Unit

2.00309424954233 --> No Conversion Required

FINAL ANSWER

2.00309424954233 ≈ 2.003094 <-- Constant of Machine Construction
