Recently, there has been significant attention given to the electrification of transportation due to concerns about fossil fuel depletion and environmental pollution. Conventional drive systems typically include a clutch, reduction gear, and mechanical differential, which results in power loss, noise, vibration, and additional maintenance. However, in-wheel motor drive technology eliminates the need for these components, providing benefits such as higher system efficiency, improved wheel control, and increased passenger comfort. This article offers a comprehensive review of the technology and development of in-wheel motor drives. It begins with an overview of in-wheel motor drives in electric vehicles, followed by an exploration of the types of electric motors suitable for in-wheel motor drives. The paper then presents an industrial state of the art of in-wheel motors, comparing them with conventional motor drives, and reviews the implemented power electronics, control system, and cooling systems. Finally, the paper concludes by providing an outlook on the challenges and future trends of in-wheel drive systems.

“…Direct torque control (DTC) is another classic technology of AFPM motor control, and DTC refers to the technology of directly controlling the flux and torque obtained by predicting the measured voltage and current [105]. Siami et al proposed a DTC method for AFPM machines [106], and the block diagram of proposed DTC is shown in Figure 10a.…”

Axial-flux permanent-magnet (AFPM) motors are a kind of important motor with compact structure, high power density and high torque density. In this review, the progress of AFPM motors and their key technologies are analyzed and described, with emphasis on the topological structures, design and optimization methods and control techniques. Based on these analyses, the main findings of the review are the following: (1) the yokeless and segment armature (YASA)-type motors have great potential for development; (2) the multi-objective optimization design theories can be integrated and applied to optimize the design of AFPM motors; and (3) optimal control and sensorless control have important value in improving system reliability and reducing cost. Finally, highlights and prospects are provided for further advancing AFPM motors.

“…− 𝐿 𝑑 is equal to 𝐿 𝑞 so, the AFPMSM does not have a non-salient pole effect. The AFPMSM model in a-b-c is a differential equation of variable coefficients under the above assumptions and its equations are as follows [1], [9], [13], [19]− [24]. For simple treatment with the (1) and (2), coordination transformation into a Direct-quadrature axis is used.…”

“…In the past two decades, permanent magnet machines have attracted the researcher's attention due to their high power to weight and good dynamic performance and are considered highly efficient motors, and can be used in many applications. Permanent magnet synchronous motors (PMSMs) are divided into two categories: Axial flux permanent magnet synchronous motor (AFPMSM) and radial flux permanent magnet synchronous motor (RFPMSM) [1]− [4]. Because of their high-power density and small size, AFPMSM can…”

“…Vector control provides a better steady-state output for the motor, but it has a poor dynamic performance. Adjusting parameters is also needed, which will result in performance affection [1], [2], [9]− [12]. The conventional type of direct torque control (DTC) that uses a voltage source inverter (VSI) is non-complex, as it does not contain a current regulator and no PWM space voltage generator to provide good dynamic performance.…”

Axial flux motors use less material and thus are inherently less expensive. They can also deliver a high-power density, which is four times that of a radial flux motor. That makes studying the control methods for this motor necessary. The purpose of this study is to introduce a new dynamic and steady-state response control technique for axial flux permanent magnet synchronous motors (AFPMSMs). Dynamic equations describe the control characteristics of axial flux permanent magnet motors. The AFPMSM model and the space vector pulse width modulation (SVPWM) inverter were created using MATLAB Simulink. For the AFPMSM motor with an SVPWM inverter, direct torque control (DTC) is provided. The results of the proposed control technique are simulated and analyzed, and it is found to provide good performance. According to the results, the proposed control method reveals advantages in reducing the ripples and pulsating of the torque while enhancing speed dynamic and steady-state response.
