Armature Current of Shunt DC Motor given Torque Solution

STEP 0: Pre-Calculation Summary

Formula Used

Armature Current = Torque/(Constant of Machine Construction*Magnetic Flux)
I_a = τ/(K_f*Φ)
This formula uses 4 Variables

Variables Used

Armature Current - (Measured in Ampere) - Armature Current DC motor is defined as the armature current developed in an electrical dc motor due to the rotation of rotor.
Torque - (Measured in Newton Meter) - Torque is defined as a measure of the force that causes the rotor of an electrical machine to rotate about an axis.
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

Torque: 0.85 Newton Meter --> 0.85 Newton Meter 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
