Over the past few decades, there have been an increasing number of research done onto using magnetic gears to replace mechanical gearing in electric motors as they provide several advantages such as reduced maintenance and improved reliability, inherent overload protection, and physical isolation between the input and output shaft [3]. However, one problem with traditional magnetic gear topologies will be that their torque transmission capabilities and efficiency are generally poorer than their mechanical counterparts. Despite this, recent studies have shown that Magnetic-Geared Machines (MGMs) can produce high transmitted torque density comparable with its mechanical counterparts. The goal of this project is to propose a design for a direct-drive electric motor with high fault-tolerance for electric vehicles. The project aims to give a comparative study between PMSMs and PMVMs
