N2 - This paper introduces a novel magnetic coupling (MC) topology, which is able to achieve significant torque density values by adding a limited amount of extra permanent magnets (PMs). Indeed, the proposed MC architecture, namely enhanced magnetic coupling (EMC), includes both axial and radial concepts in the same structure. In particular, one radial and two axial MCs are considered and embedded in a single device. Hence, this configuration allows to boost the transmitted torque that is sum of three contributions, while keeping almost unaltered the overall device's volume. The geometry of the EMC is discussed and a 2D subdomain analysis is employed for its preliminary study and fast performance evaluation. The results obtained by the 2D subdomain approach are then compared and validated against 3D finite element method (FEM).
