No Load Current Calculator

Formula

To calculate the No Load Current (\(I_{N-L}\)):

\[ I_{N-L} = FLC \times \frac{R}{100} \]

Where:

\(I_{N-L}\) is the No Load Current (amps)
\(FLC\) is the full load current (amps)
\(R\) is the percentage of full load current (%)

What is No Load Current?

No Load Current is the current drawn by a motor when it is running without any load. It is calculated by multiplying the full load current by the percentage load factor over 100.

Example Calculation 1

Let's assume the following values:

Full Load Current (\(FLC\)) = 50 amps
Percentage of Full Load Current (\(R\)) = 10% (Star Motor)

Using the formula:

\[ I_{N-L} = 50 \times \frac{10}{100} = 5 \text{ amps} \]

The no load current is 5 amps.

Example Calculation 2

Let's assume the following values:

Full Load Current (\(FLC\)) = 100 amps
Percentage of Full Load Current (\(R\)) = 30% (Delta Motor)

Using the formula:

\[ I_{N-L} = 100 \times \frac{30}{100} = 30 \text{ amps} \]

The no load current is 30 amps.
