A certain 3-phase induction motor has a torque developed of 345 N-m when running at a slip of 0.01. The rotor copper loss at this slip is 5.69 kW. Assume that the rotational losses are negligible. a) If the rotor circuit resistance is increased by 5 times, determine the torque developed if the slip is also assumed to be increased by 5 times to 0.05. WebThe speed will settle when the slip has increased to the point where the developed torque equals the load torque – e.g. point B in Figure 7. Fig. 7. Induction motors are usually designed so that their full-load torque is developed for small values of slip. Small ones typically have a full-load slip of 8%, large ones around 1%. cannonball rag chords merle travis
