Abstract

Structure integration has drawn much attention in mechatronic design. This paper presents a compact component which combines the functions of an axial piston hydrostatic motor and a permanent magnet electric generator together. The integrated machine is realized by mounting a Halbach permanent magnet array which has self-shielding magnetic property on the surface of the motor's barrel, and then direct energy conversion between hydrostatic and electrical is sustained through the torque balance acting on the compound rotor. Tradeoff design is carried out for significant parameters based on the utilization of some standard parts. A prototype is fabricated and tested under no-load and loaded conditions. The results show that the prototype has small volume and moment of inertia, reasonable efficiency, as well as good generation quality and output voltage stiffness, which verifies the effectiveness of the proposed structure and design methodology.
综合水力发电机的研制
结构集成化是机电一体化设计中备受关注的问题。本文介绍了一种集轴向柱塞静压电机和永磁发电机功能于一体的结构紧凑的部件。在电机筒体表面安装具有自屏蔽磁性的哈尔巴赫永磁阵列,通过转矩平衡作用于复合转子,实现静、电能量的直接转换。通过对部分标准件的利用,对重要参数进行了权衡设计。制作了样机,并在空载和有载条件下进行了试验。结果表明,样机具有体积小、转动惯量小、效率合理、发电质量好、输出电压刚度好等特点,验证了所提结构和设计方法的有效性。
