Motor Full Load Current Estimator (HP)

This calculator provides an ESTIMATION of motor full load current based on the voltage, phases and horsepower rating. A calculator which takes watts as an input can be found by clicking here.

We have used an empirical model for adjusting the full-load current for efficiency and power factor based on the motor rating.

Although this calculator provides a reasonable estimate, always consult the manufacturers data for an accurate figure.
