This motor has a service factor (SF) of 1.0 and yet the SF amps > full load amps (FLA).
As I understand it, service factor is the allowed total load in an overload situation (not sure for how long, but I assume something like high starting torque situations which are brief).
So this motor seems to be saying, in effect, that no overload is allowed. Therefore I would have expected that the FLA = SFA, but it does not.
Comparing the actual SFA and FLA values, SFA is about ~1.14 of FLA. So you'd think that would be roughly the SF as well.
This was used on a machine (air compressor) labelled as "6 HP" and the motor nameplate also reads 6 HP in the crease of the label (to the right of the model #).
Why are the SFA and FLA different for this motor?
