Dear Ahmed,
The right way of representing base torque as Tbase = Sb*pole pairs/wb. where, Sb is apparent power VA, wb in electrical rad/sec. The machine parameters window do not taking pole pairs data. So induction machine model is considering base torque as Tbase = Sb/wb. However to recalculate actual torque from per unit torque (Tpu) which is obtained from the model, it need to multiply with pole pairs that means Tactual = Tpu*(Sb*pole pair/wb).
I hope it is answered.
Thank you.
