The main aim of this work is the study and comparative analysis of electric motors for small vehicles. The utilization of these motors is devoted to the application in hybrid vehicles and, in particular, for the series connected configuration. Three feasible solutions of permanent magnet machines are proposed and discussed. In particular, the machines are permanent magnet motors with radial flux (two) and axial flux (one) structures. A preliminary design of the electrical machines is carried out by means of a traditional approach. Hence, the Finite Element Method has been applied through the utilization of a commercial software that allowed to evaluate the values of both the electrical and electromagnetic fields, and to carry out a refined design of the machines. A trade off conclusion has finally been done by taking into account the advantages and drawbacks of the proposed propellers into the investigated configuration.
