永磁同步直线电机端部效应的分析及结构优化

Analysis and Structure Optimization on End Effect of Permanent Magnet Synchronous Linear Motor

根据麦克斯韦理论,对永磁同步直线电机磁场的端部效应进行有限元建模、仿真和分析,并在此基础上对单电机和基于相叠加原理的多电机移结构进行优化,从而设计了圆筒型直线电机,并与排推动型直线电机的端部效应进行比较,说明优化后的结构模型对更好地改善了端部效应.

Based on Maxwell theory,the end effect on the magnetic field of permanent magnet synchronous motor is constructed by finite element method,simulation and analysis. In view of the above results,the structure of the motor is optimized by the single and superposition-principle based motor. A cylindrical linear motor is designed,and the end effect of the cylindrical linear motor is compared with that of the array promoting linear motor,which proves that the structural model of the optimized structure has better improved the end effect.
