The formula to calculate the EMF is:
\[ E = \frac{N_{\text{r}} \cdot Z \cdot \Phi_{\text{p}}}{60} \]
EMF is defined as the electromotive force needed to move the electrons within an electrical conductor to generate the flow of current through the conductor.
Let's assume the following values:
Using the formula:
\[ E = \frac{1200 \cdot 12 \cdot 0.06}{60} = 14.4 \text{ V} \]
| Rotor Speed (Nr) | EMF (E) |
|---|---|
| 1000 RPM | 12.00 V |
| 1100 RPM | 13.20 V |
| 1200 RPM | 14.40 V |
| 1300 RPM | 15.60 V |
| 1400 RPM | 16.80 V |
| 1500 RPM | 18.00 V |
