Handbook of Electrical Engineering - PDF Free Download P = 1.0 the torque corresponding to the positive root is T = 0.667 pu, whilst that for the negative root is T = 1.00 pu. Hence the torque at full-load power is less than unity (due to the speed being higher than unity). The above example illustrates the impractical nature of the open-loop speed-torque and speed-power characteristics.
