dc.description.abstractHigh-speed electrical motors are increasing the application fields where they are used, and vehicle applications are one of them. These motors offer advantages when compared to conventional ones, mainly because of the fact that they offer a high power in a relative small size. For that reason, their application in mobility systems is increasingly under study, since they arise as a powerful alternative for sustainable transportation systems. This thesis is part of a project in which a high-speed electrical motor for vehicle applica-tions will be designed. In the development of the motor there are several design fields that need to converge, mainly the mechanical, electrical, structural and thermal aspects, always considering the cost-efficiency of the project. In this thesis, the analysis of the dynamic behaviour of one part of the motor, actually the rotor, will be conducted. In order to do that, the rotordynamic aspects which have great influence in the behaviour of the motor will be described. The most important dynamic features, such as the critical speed, the natural frequencies and the vibration modes, as well as the stress due to centrifugal forces that take place in the operational speed range will be determined.
