永磁同步电机驱动的液压动力系统设计与实验分析
System Design and Experimental Analysis for Hydraulic Power Unit with Permanent Magnet Synchronous Motor Drive
摘要
Abstract
For the traditional hydraulic power system driven by the asynchronous motor（ASM） has some defects in practical applications such as low efficiency,slow response and instability at low-speed,this paper researched a new energy-saving hydraulic power system based on the permanent magnet synchronous motor（PMSM） which had good performance in energy-saving and speed regulation and the gear pump which had good performance in reliability.And an experimental system was designed under the guidance of energy-saving and frequency control theory.The experimental results prove the feasibility of such a power source,show some unique system performance and technical advantages,and show that the hydraulic power driven by the PMSM is better than the hydraulic power driven by the ASM in power matching of the load,response time and speed regulation precision,especially in the energy-saving of the low-speed and light load.关键词
