摘要
针对煤矿刮板输送机传统驱动系统存在的传动效率低、过载能力不足及机械可靠性差等问题,提出了一种基于内置切向式转子结构与机壳螺旋水冷系统的永磁直驱电机优化方案。通过转子拓扑创新与热管理硬件协同设计,显著提升了电机的转矩密度、抗冲击性能与散热效能。实验结果表明:过载倍数达2.17以上,效率提升至96%,绕组温度稳定控制在35℃以内,转子关键部位应力较材料屈服强度裕度超过36%,机壳振动速度有效值优于国家标准。该研究为煤矿输送装备提供了高可靠性直驱动力解决方案,推动了永磁直驱技术在矿山装备中的深化应用。
Addressing issues such as low transmission efficiency,insufficient overload capacity,and poor mechanical reliability in traditional drive systems for coal mine scraper conveyors,this study proposes an optimized permanent magnet direct drive motor solution featuring an embedded tangential rotor structure and a spiral water-cooling system integrated into the motor housing.Through innovative rotor topology and coordinated thermal management hardware design,the motor's torque density,shock resistance,and heat dissipation efficiency are significantly enhanced.Experimental results demonstrate:overload capacity exceeds 2.17 times,efficiency reaches 96%,winding temperature is stably controlled below 35℃,stress at critical rotor locations maintains over 36% margin relative to material yield strength,and housing vibration velocity RMS values outperform national standards.This research provides a highly reliable direct-drive power solution for coal mine conveying equipment,advancing the deep application of permanent magnet direct-drive technology in mining machinery.
