这一技术或将成为风口，仍有短板亟待解决？

Core Viewpoint - The article discusses the advantages and challenges of hub motors in the electric vehicle (EV) industry, highlighting their potential to simplify vehicle design and improve efficiency while also addressing the technical hurdles that need to be overcome for broader adoption [4][5][9]. Group 1: Advantages of Hub Motors - Hub motors eliminate the need for complex mechanical components such as clutches, gearboxes, and drive shafts, leading to a more direct and efficient power transmission [4][5]. - Each wheel can be independently driven, allowing for flexible driving modes such as front-wheel drive, rear-wheel drive, and all-wheel drive, enhancing vehicle maneuverability [5][6]. - Hub motors facilitate energy recovery during braking, converting kinetic energy back into electrical energy, which increases energy efficiency and extends vehicle range [9]. Group 2: Challenges of Hub Motors - The increase in unsprung mass due to the motor being part of the wheel can negatively impact ride comfort, traction, and handling precision [7]. - Hub motors are subject to greater impacts from road conditions, which can affect their durability and the lifespan of components like bearings and rotors [7][8]. - Manufacturing costs are higher due to the complexity of production and precision requirements, and maintenance can be more challenging since repairs may require disassembling the wheel [9][10]. Group 3: Future Prospects - Continuous technological advancements are expected to improve the performance and cost-effectiveness of hub motors, making them more viable for widespread use in EVs [10]. - Increased investment from automotive manufacturers and research institutions in hub motor technology is anticipated to lead to new innovations and improvements [10].
