Magnetic Flux of DC Machine given Torque Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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

Torque: 0.62 Newton Meter --> 0.62 Newton Meter No Conversion Required
Machine Constant: 2.864 --> No Conversion Required
Armature Current: 0.75 Ampere --> 0.75 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Φ = τ/(K_f*I_a) --> 0.62/(2.864*0.75)

Evaluating ... ...

Φ = 0.288640595903166

STEP 3: Convert Result to Output's Unit

0.288640595903166 Weber --> No Conversion Required

FINAL ANSWER

0.288640595903166 ≈ 0.288641 Weber <-- Magnetic Flux

What are the features of DC series motor?

In a DC series motor, the field winding is connected in series with the armature and hence carries the full armature current. When the load on shaft of the motor is increased, the armature current also increases. Hence, the flux in a series motor increases with the increase in the armature current and vice-versa.
