Abstract

A five-phase synchronous reluctance machine is modelled with no eccentricity fault, as well as other modelled of the machine with Static, dynamic and mixed eccentricities. The machine is subjected to a direct-on-line starting, loaded with a ramp load at synchronism and subsequently subjected to a loss of phase fault. The dynamic performance characteristics of flux linkage, speed and torque are considered. The load carrying capacity of the various considered machine is also determined under the faulty conditions of the machines. The eccentricity conditions of the machine gives an indication as it deviates from the rated condition of the machine. These deviations observed in static, mixed and dynamic eccentricities are less significant to a 2 places of decimal for condition of synchronism at start and on load, but show significances to 1-place of decimal on loss of phase fault. The flux linkages separated by a.
