WebJan 10, 1999 · T = k x Nslip = k x (Nsync - N) An example: You have an induction motor rated at 2 hp at 1750 rpm (Nslip = 50 rpm). T = 63000 x 2 / 1750 = 72 in-lb. Now we find that the motor is actually running at 1775 rpm (Nslip = 25 rpm). With Nslip cut in half, torque is cut in half to 36 in-lb. HP = 36 x 1775 / 63000 = 1.01 HP.
