  • Abstract
    In this paper the torque density characteristics for an axial magnetic gear using a flux focusing topology is studied when using (NdFeB) rare-earth magnets. The torque density is improved by conducting a basic geometric sweep analysis of the most important variable parameters. It is calculated that an extremely high torque density can be achieved with low torque ripple. The mechanical assembly is presented.
