“…In this paper, rotating eddy current couplers (also known as break, drive, damper, or retarder) with PM excitation are studied. There are many improved types of devices using the same operating principle, such as those with linear motion [43][44][45], those using electrical excitation [46][47][48][49] and hybrid excitation [50], and high-temperature superconducting materials that make PMs to enhance magnetic fields [51]. On the conductor rotor side, superconducting materials [48,[52][53][54][55], ferromagnetic materials [56,57], and PMs [58][59][60][61][62][63][64][65] on the conductor disk side are used.…”

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.

“…The axial-flux PMECs have larger rotational inertia and lower alignment requirements, but they will generate axial force, which reduces their bearing life [12]. Additionally, innovative structures have been developed based on these designs, such as the double-sided radial-flux type [5,[13][14][15], double-sided axial-flux type [3,16] and radial-axial combined type [17,18]. Mohammadi et al presented an analytical model of double-sided PMECs with two layers of PMs and carried out sensitivity analysis to investigate the influence of the design variables on the characteristics of the coupler [19].…”

The permanent magnet eddy‐current coupler (PMEC) is a kind of non‐contact, stepless speed regulation device and has been widely used in transmissions. However, the current PMECs are coaxial and cannot achieve transmission and speed regulation in intersecting axes. An intersecting‐axis permanent magnet (PM) eddy current coupler (IPMEC), which consists of a disk‐type PM rotor and a barrel‐type conductive sheet (CS) rotor arranged with intersecting axes, is proposed. It generates eddy currents through the speed difference between the two rotors and uses the non‐contact electromagnetic force between the eddy currents and permanent magnets to transmit torque. During operation, the speed can be adjusted by altering the coupling area or air gap. A theoretical model of the IPMEC based on the equivalent magnetic circuit method is presented and verified by finite element simulation using ANSYS. Then, the effects of the pole number of the PMs, the radius of the CS rotor and the PM rotor on the performance were analysed, and the design method of the IPMEC was proposed. This study can be used to expand the application range of PMECs.
