Feng Jianghua. Research on the Permanent Magnet Synchronous Motor Drive Systemfor High-speed EMUs[J]. Electric Drive for Locomotives, 2016,(4):1-5. DOI: 10.13890/j.issn.1000-128x.2016.04.001.
To achieve high energy-efficiency of high-speed EMUs, PMSM traction system for high-speed EMUs was developedbased on CRH380A technical platform. Overall technical parameters, traction characteristic curve design, main circuit of traction system,main parameters of PMSM and traction converter, type of cooling, thermal management technology, main circuit topology structureand PMSM control strategy were introduced. Experimental results and practical application verified the reliabilities of PMSM tractionsystem, traction converter and PMSM control strategy. The motor rated efficiency of the PMSM traction system could reach 98%, whichdecreased the energy consumption of high-speed EMUs distinctly
