Multiple coupled circuit modeling (MCCM) of squirrel-cage induction motors (SCIMs), or winding function approach is the most detailed and complete analytical model used to analyze the performance of faulty SCIMs. Already, in variate papers this approach was used to 3phases SCIMs, but this paper extends the above-mentioned model to 6phases SCIMs. Various simulations of variative faults are carri...

In this paper an approach in data envelopment analysis dealing with evaluation of non – zero slacks was propounded. This approach intends that weight of inefficient and weak efficient points that have been evaluated as zero weight, be considered as positive weight, and also in this approach, the pareto efficiency evaluates the picture of this point. In this approach positive weights in the i...

Nowadays, finite element analysis represents the most accurate tool to analyse electrical machines. However, time domain resolution of electromagnetic problem, in some cases, requires long simulation due induced nature currents. The computational burden increases when machine features a skewed layout on stator or rotor structures, since this 2D multi-slices approximated even full 3D model. In p...
