Experimental chaos and fractals in a linear switched reluctance motor

This paper addresses a prototype of linear switched reluctance motor which encounters chaotic behaviors under some specific feeding conditions. At first, the nonlinear phenomena, as bifurcations and chaos, are observed by simulating a five dimensional simplified model. The main approach is to develop a methodology for evaluating the fractal dimension and validate it on simulated data before applying it to experimental data produced by the instrumented test bench. Note that very few experimental chaos in electrical machine have been reported in literature.
