【摘要】 提出了轴向柱塞泵和永磁同步电机一体化的动力单元,介绍了永磁同步轴向柱塞液压电机泵的结构和工作原理。利用ANSYS/Emag模块对带有不同冷却流道的电机泵模型对应的空载和负载电磁场进行数值计算,在对结果进行处理的基础上,得到不同电机泵模型的电磁场分布及油隙磁感应强度,并进行了对比分析;通过将ANSYS中的负载油隙磁感应强度数据导入MATLAB进行傅立叶分析,得到基波和高次谐波的分布情况。研究表明,带有12个条形冷却流道的电机泵铁心不易饱和,谐波影响最小。所做研究对永磁同步驱动轴向柱塞液压电机泵的设计与优化提供了理论依据。更多还原

【Abstract】 Power unit which integrates the principle of axial piston pump with permonent magnetic synchronous motor is conceived,its structure and working principle is introduced.ANSYS/Emag module is applied to sumulate the electric magnetic field of the motor pump with different types of cooling channel under the condition of load and unload.Based on the simulation results,further processing and analysis is carried out to get the electric magnetic field distribution and magnetic induction intensity within oil gap for different motro pump models.By inputing data of magnetic induction intensity within oil gap into software MATLAB and analyzing with Fourier,the distribution of harmonic and foundamental is obtained.The research shows that the motor pump core with 12 rectangle section channel with circle end is not easy saturation.The investigation provides the basis for designing and optimating the hydraulic motor pump.更多还原
