Abstract

Linear drive technologies are steadily expanded in various applications, especially in industry, where high precision electrical direct drive systems are required. In this paper a double-sided permanent magnet linear motor is presented. Its characteristics are computed by means of 2D FEM magnetic field analysis. The analysis model taking into account the EM Losses and secondary moving is proposed. The Magnetic force is calculated at various triangles using Maxwell. The simulation results are found to be a good prediction to the total Energy Error and total Power Loss.
