This paper reports on the preliminary electromagnetic analysis of a 1:20 gear ratio coaxial magnetic gear (MG) motor for use in an electric vehicle traction application. Both 2-D and 3-D finite ...

This paper is to propose a new design method of permanent magnet (PM) machines with multiple arc pole ratios in stator teeth (MAPR-PMMs), in which edges paralleled to airgap in stator teeth adopt ...
