Analytical representation and finite element analysis of magnetically-geared permanent magnet machines

Recently, magnetic gears have drawn significant interest as a promising alternative to their mechanical counterparts by introducing features such as generating high torque at low speed, reduced acoustic noise and vibrations, low maintenance, inherent overload protection, improved reliability, physical isolation between shafts, and contactless power transfer. Conventional electrical machines can be combined with magnetic gears to form a compact device called a magnetically-geared machine. They have found their way into mechatronics, wind turbines, wave energy generation and electric vehicles. Such devices can be studied by numerical techniques or analytical frameworks. The former such as finite element methods (FEM), although powerful, is expensive and time-consuming, while the latter approach like flux-tube based models provide a flexible yet reasonable solution for preliminary designs and optimizations.
