The main limitation of magnetic gears is their relatively low torque density. Therefore, a novel structured high torque density magnetic-geared permanent magnet (MGPM) machine, which combines the advantages of a conventional MGPM machine and magnetic gear to enhance the torque considerably and achieve low-speed high-torque operation, is proposed in this study. However, there are different structures for increasing torque of a machine. Therefore, in order to demonstrate the advantages of the proposed structure, it is compared with other structures, using the finite element method. Moreover, the proposed MGPM machine can transmit an additional 42.3% of torque density when compared with the conventional MGPM machine of the same size.INDEX TERMS Bi-directional flux modulating, bread-Loaf shaped permanent magnet, dual-layer permanent magnet excitations, electrical continuously variable transmission (E-CVT), Halbach permanent magnet arrays, MGPM machine, torque density.
