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

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