Design and Optimization of a PMASR Motor for Low-Voltage E-Scooter Applications

The aim of this paper is to propose an accurate and effective procedure to design a low-voltage permanent magnet assisted synchronous reluctance machine by means of a FEA-based multi-objective optimization. The proposed procedure allows to obtain design solutions that satisfy given overload and flux-weakening capabilities within the voltage and current limits imposed by the battery and inverter Volt-Ampere rating. The paper starts with the presentation of the design requirements and the discussion of the optimization parameters and objectives. Then, the proposed design procedure is presented in detail step by step. Finally, a prototype is manufactured and tested to Investigate the reliability of FEA results.
