000001872 520__ $$2eng$$aSquirrel cage induction motors are employed in various machines and means of transport mostly as traction motors. The usage of this type of motors in vehicles can be connected with possible fatigue problems because of non-stationary loading and changing operational conditions. The complex dynamic model of an electro-motor rotor is described in this paper. It is based on solid and beam finite elements, on rigid bodies and on special couplings derived in a rotating coordinate system. The loading conditions and states are summarized and each dynamic excitation caused mainly by electro-magnetic field fluctuations and or track irregularities is described. The whole methodology was supported by experimental measurements and it was applied to a real motor.
