Design of tapered and straight stator pole switched reluctance machines

[摘要] ENGLISH ABSTRACT:This thesis deals with the design and optimisation of medium power traction switchedreluctance machines with tapered and straight stator poles. Only the prototype of thetapered stator pole machine is constructed and evaluated in this study.A non-commercial finite element package is used in the design and optimisationof the machines. The finite element method is applied directly in the optimisationprocedure to optimise the design of the machines in multi-dimensions. The lumpedcircuit analysis method is used only for the purpose of verifying some of the finiteelement calculated. It is not used in the optimisation procedure.The performance characteristics of the tapered and straight stator pole machinesare compared and discussed and the tapered stator pole machine is found to havebetter torque performance. Also the calculated and measured static torque versus rotorposition characteristics of the tapered stator pole machine are compared and discussed.
