AC Motor Basics
Here are the typical Full Load Amps (FLA) for 220VAC and 120VAC 1 phase 60hz electric motors.
For 230VAC 1 phase 60hz electric motors, divide the following values by 2.
They are only intended to be guidelines and in all cases, the full load amps of the motor nameplate should be used for final calculations.
