Electrical Motors - Full Load Amps

Note that most electric motors are designed to run at 50% to of rated load and that maximum efficiency usually is near 75% of rated load. For a 1 horsepower (hp) motor the load should typically be in the range 1/2 to 1 hp with maximum efficiency at 3/4 hp. Typical load ranges: acceptable for a short-period: 20 - 120%.
