What is required to compute the FLA of a motor?

To compute the Full Load Amperage (FLA) of a motor, it is essential to consider the power factor and motor efficiency because these factors provide a complete picture of the electrical performance of the motor. The FLA is calculated based on the power being used by the motor to produce its rated horsepower under full load conditions.

The power factor is a measure of how effectively the motor converts electrical power into mechanical power, impacting the actual current drawn by the motor. Motor efficiency communicates how much of the input power is converted into useful work, which is vital for accurate calculations. Both of these factors interact with the motor's horsepower rating to determine the actual current draw.

While the horsepower rating is significant, it does not give a complete assessment of current usage without considering efficiency and power factor. The other options, which suggest varying combinations of specifications such as torque, voltage, wattage, and cable length, either do not fully address the electrical performance needed for calculating FLA or are not directly tied to the computation requirements. Therefore, incorporating power factor and efficiency into the calculation is crucial for determining the accurate FLA of a motor.
