DC motor FLA
DC motor FLA
(OP)
hey guys, I'm using a 120/220VAC drive to power a 1/3 HP DC motor. I want to calculate the FLA.
What's the formula??? Can I use this relatioship 1HP =746W =746x1Vx1Amp ?
Thank you,

How do you mean? Connecting a DC motor to an AC drive? I do not understand.

Is there an excitation winding as well? If so, is it supplied by a separate rectifier - or do you supply it from the main rectifier. In the latter case, you need to add the field winding current to the total.

I = Pe/V
were:
Pe = electric power supplied in watts = Pot/EFF
V = motor input voltage
Pot = Mechanical Power output in watts
EFF = Motor efficiency
