Design of two PM Synchronous Machines for EV Traction Using Open-Source Design Instruments

By Chao Lu, Mahammad Abshari and Gian-Mario Luigi Pellegrino

Abstract

This preliminary paper pre sents a design procedure for Permanent - m agnet synchronous motors (PMSMs) targeting one PM - assisted synchronous reluctance (PMA S y R) motor and one surface mounted PM motor with concentrated windings ( CW - SPM) for EV application . The design process takes advan tage of a combination of design equations, finite element analysis (FEA) and multi - objective optimization. EV application was chosen for its many challenging aspects, including magnetic and multi - physical modelling. T hermal and structural aspects are also included in the study. The preliminary results presented in this short paper are the e fficiency maps and the limits of operation in the torque and speed domain of the two motor designs , and the comparison with selected benchmark designs . Index Terms — Perma nent - magnet motor, Traction motor drives, Automatic design, Finite element analysis , Open - Source
