Field Current of DC Shunt Motor Calculator

Calculate Field Current





Formula

The formula to calculate the Field Current is:

\[ I_{\text{f}} = \frac{V_{\text{sp}}}{R_{\text{sh}}} \]

Definition

Field current refers to the electrical current that is supplied to the field winding or field coil of an electric machine, such as a generator or motor.

Example Calculation

Let's assume the following values:

Using the formula:

\[ I_{\text{f}} = \frac{239}{159} \approx 1.50314465408805 \text{ A} \]
