“…It should be noted, however, that axial water jackets have a more severe loss in pressure than spiral water jackets for the same amount of heat transfer area [86]. In [87] investigated the effect of flow-rate of the cooling water to optimize the electromagnetic performance of the motor. The thermo-fluid coupling method is used in [88] to analyze the effect of water channel structure parameters on the heat dissipation of the PM in the IWM shown in Figure 13.…”

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.
