Weight reduction of permanent magnet disc motor for electric vehicle using genetic algorithm optimal design procedure
(IEEE, 2009-05)
Cvetkovski, Goga V.
;
Petkovska, Lidija B.
In this paper a topology optimal design of a permanent magnet disc motor (PMDM) based on total motor weight minimisation is performed. In the design procedure performed on the PM disc motor, genetic algorithm, as an optimisation tool is used. The application of the permanent magnet disc motor is in electric vehicle and therefore it is essential the weight of the motor to be as minimal as possible. Comparative values of the improved motor parameters in relation to the basic model for both models are presented.

Method of genetic algorithms (GAs) has been started to be widely used, as an optimization technique of electrical machines, in the recent years. In this paper the GA method will be applied on the shaded-pole motor, aiming towards an improvement of its operational and performance characteristics. The authors develop two new improved motor models, starting from the basic one. In the first motor model the electromagnetic torque, as a target function for optimization is suggested, while in the second one the optimization is based on the efficiency factor, used as a target function. The results gained from the both motor models are analyzed and compared to the basic model. The conclusions regarding the more favorable target function for optimization of a single phase shaded-pole motor are presented.

Performance Evaluation of an Axial Flux PM Motor Based on Finite Element Analysis
(IOS Press, Amsterdam, 2006)
In this paper a performance analysis of an axial flux PM motor based on finite element analysis (FEA) is presented. The quasi-3D method which is adopted for this analysis is consisted of a 2D FEM calculation of the magnetic field in the three dimensional radial domain of the disc motor. The magnetic field distribution is calculated at different armature current and different rotor displacements for all five segments of the motor. Using the results from the FEA the electromagnetic and electromechanical characteristics are going to be presented and a performance evaluation of the motor will be carried out.
