At s = 1, the inclusion of external resistance will reduce the stator current at standstill and also raise the power factor. This is depicted on the induction motor circle diagram in Figure 7.11 [8]. The normal short-circuit point is P1, and with added resistance it moves to P2. Enough resistance can be added so that maximum torque PM is obtainable; any additional resistance will decrease the torque.

So, efficiency can be determined easily in an appropriate manner using the circle diagram simulated via software if the specifications of the machine are given. This work can also be treated for pedagogic improvement or learning. Virtual laboratory tests may be performed for further study.
