Magnetic Flux of DC Shunt Motor given Kf Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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.
Constant of Machine Construction - Constant of Machine construction is a constant term which is calculated separately to a make calculation less complex.

STEP 1: Convert Input(s) to Base Unit

Back EMF: 231 Volt --> 231 Volt No Conversion Required
Angular Speed: 161 Revolution per Second --> 1011.5928344044 Radian per Second (Check conversion here)
Constant of Machine Construction: 2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Φ = E_b/(ω_s*K_f) --> 231/(1011.5928344044*2)

Evaluating ... ...

Φ = 0.114176372223913

STEP 3: Convert Result to Output's Unit

0.114176372223913 Weber --> No Conversion Required

FINAL ANSWER

0.114176372223913 ≈ 0.114176 Weber <-- Magnetic Flux
