Computational method of rotor stress analysis for various flux switching machine using J-MAG

Rotor is one of the core component in flux switching machine (FSM) that wield mechanical stress. It is very important to identify the maximum tensile strength of the rotor. Beyond the maximum tensile strength, the rotor will deform or crack. In the research, stress analysis for the tensile strength is measured through principal stress. The stress analysis is conducted to analyze the principal stress of the rotor in response to increasing speed. On top of that, using J-MAG, stress analysis is able to obtain the displacement and the nodal force experience by the rotor. Several type of rotors such as parallel width-rotor, non-parallel width rotor, fin-shape rotor, multi-tooth rotor, u-shape rotor, outer rotor and parallel curve rotor were experimented for the maximum principal stress, the rate of displacement and the increment rate of nodal force that will identify the best range of speed for these rotors.
