Thesis (MEng)--University of Stellenbosch, 2000. / ENGLISH ABSTRACT: This thesis deals with the design and optimisation of medium power traction switched
reluctance machines with tapered and straight stator poles. Only the prototype of the
tapered stator pole machine is constructed and evaluated in this study.
A non-commercial finite element package is used in the design and optimisation
of the machines. The finite element method is applied directly in the optimisation
procedure to optimise the design of the machines in multi-dimensions. The lumped
circuit analysis method is used only for the purpose of verifying some of the finite
element calculated. It is not used in the optimisation procedure.
The performance characteristics of the tapered and straight stator pole machines
are compared and discussed and the tapered stator pole machine is found to have
better torque performance. Also the calculated and measured static torque versus rotor
position characteristics of the tapered stator pole machine are compared and discussed. / AFRIKAANSE OPSOMMING: Die tesis beskryf die ontwerp en optimering van medium drywing trekkrag geskakelde
reluktansie masjiene met tapse en reguit stator pole. Slegs 'n prototipe van die tapse
stator pool masjien is gebou en geëvalueer.
Die masjiene is ontwerp en geoptimeer met behulp van 'n nie-kommersiële eindige
element metode pakket. Die eindige element metode is direk in die optimerings algoritme
gebruik vir die optimering van die masjiene in multi-dimensies. Die gekonsentreede
parameter stroombaananalise is slegs gebruik om sommige van die eindige
element berekenings te verifeer.
Die vermoës van die tapse en reguit stator pool masjiene is vergelyk en bespreek.
Die resultate toon dat die tapse stator pool masjien se draaimoment vermoë beter is as
die van die reguit stator pool masjien. Die berekende en gemete statiese draaimoment
teenoor rotorposisie van die tapse stator pool masjien is ook vergelyk en bespreek.
