Abstract

The efficient utilization of energy stands as a paramount priority on the international stage. Currently, there are various issues associated with the multi-power source couplers in automobiles. Addressing concerns related to the large size, poor reliability, low durability, and inefficient energy conversion of these couplers, a novel Permanent Magnet Synchronous Mechatronic-Electro-Hydraulic Coupler (MEHC) has been proposed. This system integrates a traditional permanent magnet synchronous machine with a swash plate axial piston pump/motor, enabling the mutual conversion of electrical, mechanical, and hydraulic energy. This paper primarily investigates the losses and efficiency of MEHC in both pure electric motor mode and electro-hydraulic coupling mode. Compared to our group’s previous Induction Asynchronous Mechatronic-Electro-Hydraulic Coupler (IA-MEHC), MEHC demonstrates lower losses and higher torque. Additionally, the paper also computes the electrical power external characteristics and comprehensive power external characteristics of the MEHC in pure electric motor mode. In the calculations within this paper, electric power is the primary power source, and in the electro-hydraulic coupling mode, hydraulics only provide auxiliary assistance. The research outlined in this paper lays a robust groundwork for future advancements and innovations in MEHC technology. With the capacity to bolster its performance, efficiency, and reliability, this groundwork holds the promise of accelerating the rapid development and widespread adoption of MEHC in automotive applications.

永磁同步机电液耦合器外部特性研究

有效利用能源是国际舞台上的头等大事。目前，汽车中的多电源耦合器存在各种问题。为了解决这些耦合器体积大、可靠性差、耐用性低和能量转换效率低等问题，人们提出了一种新型永磁同步机电液耦合器（MEHC）。该系统集成了传统的永磁同步机和斜盘轴向柱塞泵/马达，实现了电能、机械能和液压能的相互转换。本文主要研究了 MEHC 在纯电机模式和电液耦合模式下的损耗和效率。与我们小组之前的感应异步机电液耦合器（IA-MEHC）相比，MEHC 的损耗更低，扭矩更大。此外，本文还计算了 MEHC 在纯电机模式下的电力外部特性和综合电力外部特性。在本文的计算中，电力是主要动力源，在电液耦合模式下，液压仅提供辅助动力。本文概述的研究为未来 MEHC 技术的进步和创新奠定了坚实的基础。这项基础工作能够提高 MEHC 的性能、效率和可靠性，有望加速 MEHC 在汽车应用领域的快速发展和广泛应用。
