design, simulation and comparison of permanent magnet, induction and switched reluctance generators to reduce torque ripple for industrial use

Purpose of this paper is to evaluate common structures of electric generators in industrial use (such as back-up generators in data centers); in order to study behavior of these generators, the new finite element method is used. generators are designed and analyzed based on obtained characteristics, then magnet and motor-solve simulation software’s are used to analyze behavior of the mentioned generators statically and dynamically in a time interval considering power electronic circuits and switching angles. diagrams of torque, linkage flux, acceleration, inertia and voltage are extracted from analyses and picking the best generator for emergency electricity supply in industrial use is selected through comparison.
