摘要：

This work describes the design and optimization process of a direct-drive permanent magnet synchronous machine that is suitable for electric motorcycles. The machine is designed to develop approximately the same power than a conventional 250cc motorcycle internal combustion engine. The main goal of this work is to design an outer-rotor machine that is coupled directly to the wheel (direct-drive or in-wheel motor), so it is necessary to know the dimensions and arrangements of the wheels. The direct-drive systems don't need any gearbox to drive the vehicle, so that the global efficiency is higher than conventional systems employing a gearbox. The design and performance of the machine are assessed by means of simulations using the finite element method. The finite element method is the main tool to optimize the machine's design.
