摘要

Friction forces present in the PMSM motor exert a very negative influence on its working parameters. Those effects are extremely nonlinear and their consequences have to be acknowledged at designing both the motor's mechanical construction and its control system. This paper describes a friction coefficients identification method in the PMSM based on the mathematical model. The results of simulation research have been backed up by the real-world object testing. In the first section of this paper a brief summary of the most important aspects of PMSM motors was included while the second one focuses on the theoretical description of friction model that was used during research. Third part of this paper is focused on the detailed description of the PMSM motor model and its simplifying assumptions. The fourth section contains a description and results of concluded research in the Matlab/Simulink environment. Finally, the article concludes with comparison of theoretical results and experimental results obtained from real-world motor.
