This master thesis describes the process of design and modeling of linear electric motors with permanent magnets. In the first part of the thesis a brief literature and market overview of the existing versions of linear electric motors with permanent magnets, their basic characteristics, advantages and drawbacks are given.
The main objective of the thesis is development of numerical models and analysis of linear electric motors with permanent magnets based on finite element method. The modeling and analysis of the following two models were performed: 1. cylindrical permanent magnet linear motor with dual Halbach array and 2. U shaped linear motor with permanent magnets. In order to improve the performance of the two linear motors the parametrization and optimization procedure based on Taguchi design of experiments method were done. Based on the output results obtained with numerical modeling, parametrization and optimization the geometry and the output force of both motors were improved. In the final part of the master thesis, a comparison of both linear motor versions from the point of view of the material consumption needed for their design was performed.
