3-ph Induction Motor Nameplate information

时间:03-26 整理:3721RD 点击:
Hi,
Regarding information listed on motor nameplate.
Referring to motor power, why there is a difference when you calculate power from listed current and voltage compared to listed rated power.
i.e P= sq(3) * V * I * PF * Eff.
how to mach all these values ?
Example nameplate is attached.

Regards
Wael

The power factor (cos(theta) where theta is the angle between the voltage and the load current)

What I mean, is the power you get from Equation is different (much higher) from the power on the nameplate.

The reactive power is more than the real power. (VA vs Watt)
