Angular Speed of DC Shunt Motor given Kf Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Back EMF: 231 Volt --> 231 Volt No Conversion Required
Constant of Machine Construction: 2 --> No Conversion Required
Magnetic Flux: 0.114 Weber --> 0.114 Weber No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ω_s = E_b/(K_f*Φ) --> 231/(2*0.114)

Evaluating ... ...

ω_s = 1013.15789473684

STEP 3: Convert Result to Output's Unit

1013.15789473684 Radian per Second -->161.249087088158 Revolution per Second (Check conversion here)

FINAL ANSWER

161.249087088158 ≈ 161.2491 Revolution per Second <-- Angular Speed
