Modeling and Analysis of a Multistage Linear Induction Motor Fed by a Permanent Magnet Flywheel Motor-Generator

In the present paper the authors analyze the dynamic behavior of a Multistage Linear Induction Motor (MLIM) fed by means of a suitable back-to-back converter supplied through a flywheel energy source. The MLIM is used as a heavy mass launcher. The final velocity is several tens of m/s. Regenerative braking mode is also studied, as well as the shuttle recovering phase. The dynamic mathematical model of the whole system (flywheel-converter-MLIM) has been implemented in the Simulink® environment. Several simulations have been carried out and main results are discussed
