“…Unfortunately, a higher electric current potentially causes an increase in heat during braking, leading to a risk of overheating. Both the number of coil windings and the electric current clearly influence the braking torque [30], and it is important to set optimum values for each braking system. The number of electromagnets is also considered to potentially improve the braking performance.…”

The braking system in a vehicle has the main role of slowing down the speed or stopping the moving vehicle. Compared to mechanical braking, which utilizes friction, non-contact braking has several advantages, including longer lifetime and less maintenance. One form of non-contact braking systems is the eddy current brake (ECB), an electric braking system that employs eddy currents to operate. This research focuses on the impact of magnetic field sources used in the ECB. In addition, the number of magnetic field sources is also observed. In order to achieve an ECB design that can be easily applied in any types of vehicles, including motorcycles and compact cars, a compact ECB design with an excellent braking torque is required. In this study, a compact design of the ECB is obtained by distributing the required braking torque from the disc brake into multiple electromagnets. Finite element method-based modeling has been performed to study ECB parameters, including the number of coil winding, the number of electromagnets, and the electric current. The results of this study show that the developed compact ECB could produce 93.66% of the torque required for braking.

When an implantable medical device is in radio energy transmission, due to eddy current effect, the temperature of the device will rise, causing a safety risk. In order to study the distribution law of its temperature field, this paper adopts the analysis method of electromagnetic-thermal-fluid-solid multi-physics coupling, and establishes a two-dimensional transient equivalent model of an implantable medical device radio energy transmission system, adopting the analysis method of the electromagneticthermal-fluid-solid multi-field full coupling. Among these, electromagnetic heat is applied as the heat source, considering the influence of factors, such as heat conduction and convection. By means of simulated calculation, this paper acquired one-dimensional, two-dimensional and three-dimensional images ,whose temperature and efficiency changed with frequency. Moreover, their distribution laws are also obtained. In order to verify the correctness of the simulation, this paper conducts infrared temperature measurement experiments to prove the rationality of the analysis through comparing the simulation results. The research findings of this paper can provide a basis for the design of a radio energy transmission system for an implantable medical device, improve the safety of implantable medical devices, and reduce the occurrence of medical accidents. Meanwhile, it has certain reference value to the clinical application of implantable medical devices.
