Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The electromagnetic and mechanical design aspects of optimally designed doublesided
rotor radial flux permanent magnet wind generators with non-overlap aircored
(iron-less) stator windings are analysed in this thesis. The wind generator is
implemented in a battery charging system for use in rural settlements and farms.
The optimal generator and system design is based on an accurate analytical model
and is confirmed with finite element analysis. It is shown, amongst other things,
that the electromagnetic design and surprisingly not the mechanical design,
determines the rotor yoke dimensions and, hence, largely the mass and cost of the
generator. Alternative battery charging systems are also considered and discussed. / AFRIKAANSE OPSOMMING: Die elektromagnetiese en meganiese ontwerp aspekte van optimaal ontwerpte
dubbel-kant rotor radiale vloed permanente magneet windgenerators met nieoorvleuelende
lug kern (sonder yster) statorwindings word in hierdie tesis
ontleed. Die windgenerator word geplaas in 'n battery-laai stelsel vir gebruik in
landelike nedersettings en plase. Die optimale generator en die stelsel ontwerp is
gegrond op 'n akkurate analitiese model en is bevestig met eindige element
analise. Daar word onder andere getoon dat die elektromagnetiese ontwerp, en nie
die meganiese ontwerp, die rotor juk dimensies en dus grootliks die massa en die
koste van die generator, bepaal. Alternatiewe battery-laai stelsels word ook oorweeg
en bespreek.
