“…transmission efficiency. The structure proposed in references [34,[106][107][108] cons conventional radial-flux PMECC and a double-sided axial-flux PMECC, which is coupling in a scraper conveyor, working under bad conditions including overload severe abrasion, and pollution, as shown in Figure 10a. The structures prop reference [109] can be used to obtain a load speed that can be controlled and regu adjusting the relative positions of the two rotors, as shown in Figure 10b A Halbach array is a combination of PMs with different magnetiza a certain order so that the magnetic field of one side of the PM is signifi while the other side is significantly weakened, and it is easy to obta sinusoidal distribution of the magnetic field.…”

“…A topology combining axial flux and radial flux has been proposed in references [34,[106][107][108][109]. The combination of a traditional axial-flux PMECC and a radial-flux PMECC not only makes it possible to increase the area of the induced magnetic field, but also to magnetize it in both axial and radial directions, improving the corresponding transmission efficiency.…”

Permanent magnet eddy current couplers (PMECCs) have the characteristics of contactless torque transmission, removal of torque ripple, smooth dynamic process, and adjustable speed, and can be used as couplings, dampers, brakes, and speed governors. Their applications in industry, vehicles, and energy fields are gradually expanding. At the same time, the requirements for the torque density and dynamic performance of PMECCs are increasing. Therefore, a large amount of research work has focused on the fast and accurate modeling, design, and optimization of PMECCs. This paper provides a survey on the development of PMECCs technology. The main topics include the structure and classification of PMECCs, modeling methods, loss and heat transfer analysis modeling, and optimization design. In addition, this paper shows the future trends of PMECCs research. All the highlighted insights and suggestions of this review will hopefully lead to increasing efforts toward the model’s construction and the optimal design of PMECCs for future applications.
