My motor plate said 4Kw , 380V , 8.3A , cos(fi) = 0.88
Thats values are at 50Hz.

Paul saids:
3 phase power = batteryPackVoltage * sqrt(3/2) * RMSPhaseCurrent * cos(fi)

How can I apply that equation to the original parameters of my motor?

4Kw = batteryPackVoltage * sqrt(3/2) * RMSPhaseCurrent * 0,88

380V its rms voltage, so i must use 380*sqrt(2)???
