Optimalizace provedení synchronního stroje s permanentními magnety

Abstract

Dissertation deals with the optimization of the rotor part of synchronous machine with permanent magnets, operated in generator mode. The main objective of this work is to analyze the impact of changes in the number, shape and position of parallel magnets per pole to the selected operating characteristics - reducing losses, respectively. improving the efficiency due to the elimination of selected odd harmonics of the base curve of the magnetic induction. The research work is then based not only on the simulations, but also on analytical calculations and measurements, and fundamental solved problems are always described by mathematical models, which are based on the principle of SHE - PWM (Selective Harmonic Eliminated Pulse - Width Modulation) and PAM (Pulse - Amplitude Modulation). Considering the prospects and usefulness research are the end results verified by measurements on a real prototype.
