东风首款轴向磁通分布式电驱样机下线

2024-12-20

具备高功率密度、高扭矩密度、低轴向尺寸的特点

2024年12月17日,东风汽车首款轴向磁通分布式电驱动总成样机在智新科技1号园区下线。

据了解,轴向磁通分布式电驱动总成具备高功率密度、高扭矩密度、低轴向尺寸的特点。采用中央分布式架构,深度集成双轴向磁通电机、双行星排和双电机控制器;实现单电机重量仅23KG即可输出225KW功率、670Nm扭矩,转矩密度达到29.1Nm/KG;定子塑封式浸没油冷结构,大幅提升散热效率,轴向磁通电机最高效率达97.5%;基于800V+SiC模块化一体板电控设计,各动力单元可单独控制。

智新科技副总经理曹永军表示,轴向磁通分布式电驱动总成是智新科技面向未来的重要创新产品。样机成功下线,是技术上的突破,也展现了研发团队的使命和担当。智新科技作为东风自主乘用车动力总成事业单元,承担着支撑东风新能源转型升级的使命。智新科技将继续秉承以客户为中心的理念,把技术研发视为企业发展的生命源泉,将科技创新作为推动技术进步的核心动力,不断深化先行技术创新与产品化开发的相互融合,积极迎接市场变化,灵活调整市场策略,更好满足客户需求。


Characterized by high power density, high torque density, and low axial size

On December 17, 2024, Dongfeng Motor's first axial magnetic flux distributed electric drive assembly prototype was rolled off the assembly line at Zhixin Technology Park 1.

It is understood that the axial magnetic flux distributed electric drive assembly has the characteristics of high power density, high torque density, and low axial size. Adopting a central distributed architecture, deeply integrating dual axis magnetic flux motors, dual planetary rows, and dual motor controllers; Realize a single motor weight of only 23KG to output 225KW power and 670Nm torque, with a torque density of 29.1Nm/KG; The stator plastic sealed immersed oil cooling structure greatly improves the heat dissipation efficiency, and the maximum efficiency of the axial flux motor reaches 97.5%; Based on the 800V+SiC modular integrated board electronic control design, each power unit can be controlled separately.

Cao Yongjun, Vice General Manager of Zhixin Technology, stated that the axial magnetic flux distributed electric drive assembly is an important innovative product of Zhixin Technology for the future. The successful production of the prototype is a technological breakthrough and demonstrates the mission and responsibility of the R&D team. As the powertrain business unit of Dongfeng's independent passenger vehicles, Zhixin Technology undertakes the mission of supporting Dongfeng's new energy transformation and upgrading. Zhixin Technology will continue to adhere to the customer-centric concept, regard technology research and development as the lifeblood of enterprise development, take technological innovation as the core driving force for technological progress, continuously deepen the integration of advanced technological innovation and productization development, actively embrace market changes, flexibly adjust market strategies, and better meet customer needs.
