Abstract
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.
