Hi.
Can someone provide me with help for following question:
What is the nominal torque of a 3-phase motor that has the following data:
Pn=3,0 kW, Un=400V, In=5,9A, nn=2925 rpm, cosφn=0,86

as well as some links on info about motors calculation. (Preferrably in youtube).

Thanx in advance.

P.S. Also. quick question. How do you calculate nominal torque if you know full load torque and %synchronous speed

 

Never mind. I think i found correct formula for this:
9550*(Pn/nn)=Tn.

I, however, would realy like an explanation on what is nominal torque, what is nominal power and how it differ from other kind of powers?
