Motor Full Load Current Formula

A motor's full load current is the current it draws at its rated horsepower, found from its voltage, efficiency, and power factor.

Formula

FLC = (HP × 746) ÷ (V × Eff × PF)

FLC
Full load current, in amps
HP
Motor power, in horsepower
V
Voltage, in volts
Eff
Motor efficiency, between 0 and 1
PF
Power factor, between 0 and 1
