Application of Genetic Algorithm in Permanent Magnet Linear Synchronous Motor''''s Optimization Design

PMLSM(permanent magnet linear synchronous motor)that has a new structure and wide development promise is a new type motor, but calculations of internal magnet field are very complex, so the optimal design is also very difficult. in this paper, base on analysises and calculations of magnet field, took use of new genetic algorithms and improved it, applied improved genetic algorithms to the design optimization of PMLSM. It has been proved by experiments that satisfactory results can be obtained with the optimal design of PMLSM, which opens up a new way in the analysis and the sesign of PMLSM, has a great significance in the study and the application of PMLSM.
