“…However, few high-speed EVs with multiple in-wheel motors can be found running on the road due to some key challenges, such as high cost, reliability and safety problems [16][17][18]. These problems have been drawing a significant interest from both the industry and academia [19,20]. In recent years, the motion control of high-speed smart EVs has been one of the focuses, and various integrated motion control technologies have been proposed to strengthen the vehicle's motion safety, e.g., integrated anti-slip control (ASC) and direct yaw-moment control (DYC) [5], integrated active front-wheel steering (AFS) and DYC [21], integrated roll angle control (RAC) and DYC [22], integrated advanced driver assistant system (ADAS) and DYC, etc.…”

“…Nevertheless, the conventional permanent magnet (PM) machine system in e‐UAVs adopts the gearbox to realize the power distribution, which increases the mass of propulsion systems. Therefore, in order to eliminate the gearbox, direct‐drive machines with the characteristic of large torque at low speed, such as flux modulation PM machines, are attractive to be applied in the drive system of e‐UAVs [3].…”

This study presents an improved sub-domain analytical model for the characteristic evaluation of the flux reversal permanent magnet machine with Halbach array magnets (FRPMM-HAM) in rotor slot. The influence of iron saturation is considered by equating iron reluctances into airgap. Based on the different material magnetic permeabilities, the FRPMM-HAM is divided into several regions, including slots, permanent magnets (PMs), airgap and so on. By solving the Maxwell equations in polar coordinate for each region according to the boundary conditions, the vector magnetic potential can be derived. According to the vector magnetic potential, the airgap flux density distributions are predicted and the electromagnetic characteristics are calculated. The average magnetic density of the tooth and yoke is combined with the Bertotti model to calculate the iron loss. Besides, the eddy current loss of PMs is also calculated. The accuracy of analytical results is validated via the finite element method (FEM).

Electric machines with high torque density are needed in many applications, such as electric vehicles, electric robotics, electric ships, electric aircraft, etc. and they can avoid planetary gears thus reducing manufacturing costs. This paper presents a novel axial-radial flux permanent magnet (ARFPM) machine with high torque density. The proposed ARFPM machine integrates both axial-flux and radial-flux machine topologies in a compact space, which effectively improves the copper utilization of the machine. First, the radial rotor can balance the large axial forces on axial rotors and prevent them from deforming due to the forces. On the other hand, the machine adopts Halbach-array permanent magnets (PMs) on the rotors to suppress air-gap flux density harmonics. Also, the Halbach-array PMs can reduce the total attracted force on axial rotors. The operational principle of the ARFPM machine was investigated and analyzed. Then, 3D finite-element analysis (FEA) was conducted to show the merits of the ARFPM machine. Demonstration results with different parameters are compared to obtain an optimal structure. These indicated that the proposed ARFPM machine with Halbach-array PMs can achieve a more sinusoidal back electromotive force (EMF). In addition, a comparative analysis was conducted for the proposed ARFPM machine. The machine was compared with a conventional axial-flux permanent magnet (AFPM) machine and a radial-flux permanent magnet (RFPM) machine based on the same dimensions. This showed that the proposed ARFPM machine had the highest torque density and relatively small torque ripple.
