Torque generated in DC Machine Solution

STEP 0: Pre-Calculation Summary
Formula Used
Torque = Machine Constant*Magnetic Flux*Armature Current
τ = Kf*Φ*Ia
This formula uses 4 Variables
Variables Used
Torque - (Measured in Newton Meter) - Torque is the measure of the turning force produced by the armature. It is produced by the interaction between the magnetic field of the stator and the current flowing through armature.
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 refers to the lines of magnetic force that pass through the magnetic circuit of the machine. The magnetic flux is created by field winding that is wound around pole shoes.
Armature Current - (Measured in Ampere) - Armature Current is defined as the current developed in the armature of an electrical DC generator due to movement of rotor.
STEP 1: Convert Input(s) to Base Unit
Machine Constant: 2.864 --> No Conversion Required
Magnetic Flux: 0.29 Weber --> 0.29 Weber No Conversion Required
Armature Current: 0.75 Ampere --> 0.75 Ampere No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
τ = Kf*Φ*Ia --> 2.864*0.29*0.75
Evaluating ... ...
τ = 0.62292
STEP 3: Convert Result to Output's Unit
0.62292 Newton Meter --> No Conversion Required
FINAL ANSWER
0.62292 Newton Meter <-- Torque
