In our 1 horsepower example, service factor is 1.4 and SFA are 9.8. Therefore, when this motor is asked to supply 1.4 horsepower, it will pull 9.8 amps of current. SFA is sometimes referred to as the “speed limit” or the “redline” of an electric motor.
Also asked, what is motor safety factor?
Motor service factor (SF) is the percentage multiplier that a motor can handle for short periods of time when operating within its normal voltage and frequency tolerance. In other words, it is a fudge factor that give extra horsepower when it's occasionally needed.
What is the power factor of a motor?
Inductive loads and power factors for electrical three-phase motors. Sponsored Links. The power factor of an AC electric power system is defined as the ratio active (true or real) power to apparent power, where.
What does FL Amps mean?
Full-Load-Amperage (FLA) refers to the motor's rated-current at rated-load and rated-voltage. This is the amount of current (amps) the motor will draw from the electrical system when producing its rated output horsepower. This value can also sometimes be referred to as: Running Amps, Rated Amps, or just AMPS.
