Magnetic Flux of DC Motor Calculator

Calculate Magnetic Flux











Formula

The formula to calculate the Magnetic Flux is:

\[ \Phi = \frac{V_s - I_a \cdot R_a}{K_f \cdot N} \]

Definition

Magnetic flux (Φ) is the number of magnetic field lines passing through the magnetic core of an electrical DC motor.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \Phi = \frac{240 - 0.724 \cdot 80}{1.135 \cdot 135.088} \approx 1.18754 \text{ Weber} \]
