As a type of magnetic device being able to realize contact‐free power transmission together with sufficient volumetric torque density, the field‐modulated magnetic gear (FMMG) has become a promising alternative to the mechanical gear having rigid construction yet suffering lots of issues generated by the continuous teeth friction. The conventional magnetic gears (MGs) that behave as simple copies of their mechanical counterparts and can be roughly defined as origination of the FMMG are briefly introduced at first. Subsequently, the topology and material advancements proposed to improve operational performance of the FMMG are comprehensively summarised so as to clarify its current development status. Finally, potential applications of the FMMG due to its inherent advantages are compared against the existent challenges. The review aims to provide referable guidelines for researchers working at the field of high‐performance MGs.

“…They proved that comparable transmitting torque with mechanical gears can be achieved with magnetic gear. Chen et al 34 designed a new magnetic gear with 16 controllable gear ratios by using the concept of DC-excited memory machines. Despite considerable benefits such as silent operation, high flexibility in gear ratio, the proposed design was costly and complicated.…”

With the development of hybrid electric vehicles and wind turbines, the demand for improved efficiency, increased maintenance life, increased reliability, reduced noise, and environmental considerations has increased. Meanwhile, magnetic gearboxes, in particular the technology of continuous variable transmission (CVT) systems, provide an opportunity to meet these needs. In this paper, while presenting four topologies of a novel coaxial hybrid-rotor CVT magnetic gearbox with a consequent-pole high-speed rotor, a simple precise semi-analytical model is presented based on the subdomain method for calculating the magnetic performance characteristics of the gearboxes. Magnetic equations have been rewritten in a pseudo-Cartesian coordinate system, and by applying the appropriate boundary conditions and interface conditions, the general solution and their coefficients have been extracted using the separation of the variables method. The performance characteristics of four studied gearboxes were compared semi-analytically and numerically. A prototype coaxial consequent-pole magnetic gearbox has been fabricated and the results of semi-analytical modeling have been compared with the results of numerical simulations and the experimental tests. The maximum error percentage of the results of numerical simulations and experimental tests is about three, which shows that the proposed semi-analytical model has a high accuracy. A comparison of magnetic torque, torque ripple and induced voltage is carried out between the investigated designs.
