Structural Analysis of an In-Wheel Motor with Integrated Magnetic Gear Designed for Automotive Applications

Abstract

This paper is focused on the structural analysis of a new propulsion system defined by an in-wheel motor with an integrated magnetic gear (IWM-IMG). The IWM-IMG has two levels of torque and speed. First, the state of the art of magnetic gears (MGs) is presented. Next, the proposed structure and the main designing steps are depicted. The advantages of the proposed structure are emphasized, in terms of speed increase operation, knowing that this is achieved without it being necessary to increase the fed frequency via the inverter. Moreover, the electromagnetic characteristics are briefly introduced to prove the suitability of the proposed solution for the considered application. Next, the structural analysis is detailed, where through an analytical, numerical and experimental approach, the study is validated.
