“…In addition to the radial-flux structure, the FMMG can be built in the axial-flux frames [65][66][67][68][69][70][71][72][73][74] as shown in Figure 11. The axial-flux FMMG is preferred particularly in applications requiring flat outside shapes and hermetic isolation between the input and output shafts [75].…”

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.

“…After separating both volume of PMs at both high-speed and low-speed rotor, each rotor equation is derived separately. By relating the volume of cylinder formula, the volume of PMs at low-speed rotor can be related to the parameters at low-speed rotor, consisting of the outer radius of outer rotor, the thickness of outer yoke, and the thickness of PMs at the low-speed rotor, as written in Equation (9). As shown in Equation 10, the thickness of the outer yoke, t o , is eliminated by substituting Equation 6into Equation 9.…”

“…Another MG configuration that has been studied is the axial-type MG, which comprises a high-speed rotor, flux modulator, and low-speed rotor, which are all axially stacked to create an axial magnetic flux flow. This type of MG is suitable for an application that limits the size of the MG in radial length, since the performance depends on the axial length [7][8][9].…”

Magnetic gears (MGs) technology is studied widely among research institutions, with several improvements being documented. This development attracts a high amount of attention due to the demand in the development of magnetic gears towards higher performance than the conventional mechanical counterpart. In general, the design is complicated and there is a lack in detailed references for designing an MG for specific transmission torque as required by its application. Trial-and-error approaches have been the norm in achieving the desired torque by referring the existing MGs for the desired value of torque. This paper presents a new simplified approach towards designing an MG for the required torque and size by referring through a Maximum Transmission Torque Line (MTTL) reference. Finite element method (FEM) is used in analyzing randomly designed magnetic gears with various parameters towards the desired values of the MTTL. The proposed approach of MTTL is a new approach to estimate the total volume of permanent magnets (PMs) required for the MG to achieve the desired transmission torque. The reference line is used to generate equation relating the specific parameters of MG to develop the simplified design of MG based on the estimated total volume of PMs. This simplified way details to 8.5% of error in targeting the desired transmission torque, a means and way for the first stage of the MG design approach to reduce the conventional approaches.
