This Ph.D. thesis deals with the prediction of the dynamic behavior of induction motors and especially with the lateral dynamics of squirrel cage laminated rotors known as high speed motor (HSM, [3 − 30] MW, [6 000 − 18 000] rpm). The main difficulty of the modeling is due to the complexity of the HSM magnetic mass assembly, composed of a core of laminated steel held by excentric prestressed tie rods, and a squirrel cage consisting of a distribution of short-circuit rods also positioned at the periphery of the magnetic mass and connected to two short-circuit rings located at the ends of the laminated core. A finite element model of Timoshenko beams is developed that takes into account the monolithic nature of the HSM rotors. A particular at...
