Out of curiosity, what exactly is the formula for determining the FLA on a 3 phase motor when only the KW is known?
For instance, If they say this motor is a 75hp motor, I would look at the typical FLA for a 75 hp motor and it should be around 96 amps at 480volts.
I always thought it would be:
96 X 480 = 46080
46080 X 1.73 = 79718.4
Divide by 1000 = 79.72kw
Comes out to about 80kw not 50
What am I doing wrong?
