低铁耗胶粘铁芯制备技术研究OA

This paper addresses the issues of high iron loss and insufficient structural precision in traditional riveting and welding iron cores,and explores the preparation technology of low-iron-loss adhesive iron cores in response to the demand for high-efficiency drive motors under the"dual carbon"strategy for new energy vehicles.By innovating tooling structures,optimizing adhesive dot design,and standardizing process flows,the existing adhesive dispensing process issues such as redundant adhesive volume and uneven stress distribution due to dimensional tolerances are resolved.Experimental studies show that the key performance indicators of the iron cores produced with this technology,such as pull-out force and stacking coefficient,exceed industry standards,with iron loss reduced by over 26%compared to traditional processes,making it suitable for high-end electric vehicle drive motors.
