Die optimering van die ontwerp en die elektroniese kommutasie van 'n histeresemasjien vir hoƫ rotasiesnelhede

M.Ing. (Electrical & Electronic Engineering Science) / This dissertation deals with the design and implementation of a hysteresis machine for high-speed applications. A model is introduced whereby the optimum working point of the machine can be determined. Hence it is possible to make a comparison between different rotor materials with respect to cost, specific energies and overall performance. The development of a compensator for actively controlling the phase angle of the airgap flux density, in order to reduce hunting, is discussed with reference to practical results. A technique for measuring real power in the frequency plane with the aid of a frequency spectrum analyzer, is explained. The design and evaluation of a hysteresis machine is based on practical results obtained from this measuring technique.
