Motor Service Factor Amps. If it is a 1.0 you can run a motor to 100% load, if it is 1.15, then it can be loaded to 115% of its rated load. When the voltage and frequency are maintained at the value specified on the nameplate, the motor may be overloaded up to the horsepower.

1 hp = 0.745 kw; Most hazardous location motors are made with an sf of 1.0, but some specialized units are available for class i applications. Most motors have a duty factor of 1.15 for open motors and 1.0 for totally closed motors.

Service factor is a multiplier that indicates how much a motor can be overloaded under ideal ambient conditions. The first value labeled amps or rated input amps is the expected running amps when the motor is operated at rated voltage and nameplate horsepower loads. If it is a 1.0 you can run a motor to 100% load, if it is 1.15, then it can be loaded to 115% of its rated load. Service factor amps this is the amount of current the motor will draw when it is subjected to a percentage of overload equal to the service factor on the nameplate of the motor.
