“…As shown in Figure 39(a), substitution of the mechanical gears by the FMMGs proves to be an efficient approach to improve the reliability of wind-turbine drive train because that the power transformation could be accomplished in a contactless manner, together with which the lubrication is reduced and inherent overload protection is accessible [157][158][159][160][161][162]. As displayed in Figure 39(b), the system torque density could be further improved by applying the MGPM generator to replace both the FMMG and the DFIG [163][164][165].…”

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.

“…Magnetic gear is an electromagnetic device driven by non-contact magnetic force, which has the advantages of low noise, low vibration, maintenance free, and inherent overload protection [1][2][3]. At present, magnetic gears are used in many low-speed and high torque situations, especially in combination with permanent magnet motors, such as electric vehicles [4,5], wind power generators [6,7], and marine electric propulsion [8,9].…”

In order to investigate the influence of different magnetization modes on the electromagnetic performance of magnetic gear, four models of magnetic gear with different magnetization modes are established. The finite element method is used to simulate the four models and compare their performances. The distribution of magnetic flux lines, air gap magnetic field, harmonic distribution, static torque, and dynamic torque are calculated, respectively. The simulation results show that the coaxial magnet gear with Halbach array has larger air gap flux density amplitude, smaller air gap harmonic content, and higher output torque than the other three kinds of magnetic gears.

Compared with the conventional coaxial magnetic gear, magnetic harmonic gear (MHG) is a device with large transmission ratio. In order to improve the transmission torque, an MHG with double fan-shaped Halbach arrays is proposed in this paper. According to the theory of magnetic field modulation and the unique unilateral effect of Halbach array, both inner and outer permanent magnets (PMs) are arranged in a Halbach array. In addition, all PMs are fan-shaped. The air gap magnetic field and torque of MHG are analyzed by two-dimensional finite element method. Compared with the conventional MHG, the proposed MHG enhances the air-gap magnetic flux density, reduces the air-gap harmonic content, and increases the torque density.
