Optimal design of a surface mounted permanent magnet in-wheel motor for an urban hybrid vehicle

Abstract

Many optimization methods have been proposed to design electrical machines in a wide range of power [1–3]. In this paper, the authors investigate the optimal design of a surface mounted permanent magnet (PM) in-wheel motor for the propulsion of a small power hybrid vehicle (maximal total weight of 1,000 kg). Using the sequential quadratic programming (SQP) optimization algorithm, a PM synchronous machine is optimized and the performances of the obtained solution are validated with finite element analysis (FEA).
