How do you calculate the power (in amperes) of a three-phase asynchronous motor?

Benno933ByBenno933

If I read this correctly from the rating plate (Figure 3) it has something to do with U= 400 V, P=5500W and cos (phi) = 0.84

I would be happy if someone could help me 😀

Performance is in W, VA or var, but not in Ampere. That's the current and it's on the engine type shield.

Is it a special task?

You calculate the appearance with U*I

It is given I believe in var, ie S = 10 var

And if you do the economic performance I'm S*cos phi but I'm not sure
