Optimisation of high-speed motors using a genetic algorithm

An optimisation software package for high-speed electric motors has been compiled. High-speed motors are modelled with finite element and thermal network analyses. A genetic optimisation algorithm is chosen for the optimisation and parallel computing is used to speed up the optimisation process. High-speed motors of 53,000 RPM; 50 kW and 100,000 RPM; 100 kW have been optimised. The objective of the optimisation was to minimise the motors' losses. The results justify the use of genetic algorithms and emphasise their accurate thermal modelling of high-speed motors.
