Electric Motor HP to Amps Calculator

Electric Motor HP to Amps Calculator

Convert electric motor horsepower (HP) to amps.

For a single-phase motor: \( I = \frac{HP \times 746}{V \times \eta} \)
For a three-phase motor: \( I = \frac{HP \times 746}{\sqrt{3} \times V \times \eta} \)

* Enter the motor HP, supply voltage (V), and efficiency (%). Choose the motor type.

Step 1: Enter Motor Parameters

Example: 10 HP

Example: 230 V

Example: 90% (enter 90)

Motor Type:

Single-Phase: \( I = \frac{HP \times 746}{V \times \eta} \)
Three-Phase: \( I = \frac{HP \times 746}{\sqrt{3} \times V \times \eta} \)
