摘要:
在屏蔽式电机泵的基础之上,根据永磁无刷直流电机和轴向柱塞液压泵的结构特点和运行原理,提出了一种将两者高度集成的新型液压能源系统——电液泵。通过对电液泵集成原理和结构的分析,利用有限元分析软件MagNet对电液泵进行了空载和负载状态下的电磁场数值计算与分析。仿真结果证明了所提出集成设计方案的可行性,系统内部没有出现磁场畸变与局部饱和现象,其动态性能满足技术要求。研究结果在液压能源系统的集成设计以及性能优化等方面具有理论意义和参考价值。

Abstract:
In this paper, according to the structural features and operating principles of PM brushless DC motor and axial plunger-type hydraulic pump, a new hydraulic energy system, named electrohydraulic pump, is proposed based on traditional canned motor pump.The integrating principle and structure are analyzed, and then, the elec-tromagnetic field numerical calculation and analysis of the electrohydraulic pump are conducted with MagNet under both no-load and load conditions.The simulation results verify the feasibility of proposed integrated design.The magnetic field in the system has no distortion and local saturation, and the dynamic performances satisfy the techni-cal requirements.The simulation results, we believe, provide some theoretical basis and serve as some guidance for the integrated design and performance optimization of the hydraulic energy system.
