The formula to calculate the motor current (Im) is:
\[ Im = \frac{1000 \cdot P}{\sqrt{3} \cdot V \cdot EF \cdot PF} \]
Where:
Motor current is the amount of current drawn by an electric motor. It is crucial for determining the electrical load and ensuring the motor operates efficiently and safely.
For example, if the power (P) is 10 kW, the voltage (V) is 400 V, the efficiency factor (EF) is 0.9, and the power factor (PF) is 0.8, the motor current (Im) can be calculated as follows:
\[ Im = \frac{1000 \times 10}{\sqrt{3} \times 400 \times 0.9 \times 0.8} \approx 20.09 \text{ A} \]
So, the motor current for these values is approximately 20.09 A.
