Abstract


This paper discusses the design, simulations and results of the forces acting on the moving part of a permanent magnet linear synchronous motor – the first linear synchronous servo motor designed in Bulgaria to be used in linear transportation system in the light industry. The Finite Element Method was used for simulations and the analysis results were then used for detent force and cogging force calculation. The flux linkage and the back-EMF of each motor phase were also calculated. The results obtained from force calculations showed good coincidence with the results obtained from the experimental study of the motor prototype. The models and programs proposed in this paper can be a powerful tool for the designers of flat iron core linear synchronous motors, allowing them to perform simulations during the design stage in order to verify design parameters.
