Research on Rising Pantograph Surge overVoltage for High-speed EMUs

open access: yes, 2013
Based on structure of high-speed EMUs body, equivalent electric circuit model was established to analyze the transmitting and reflecting characteristics between different car bodies, as well as experiments were carried out in field. It was demonstrated that wave figure of theoretic result was consistent with experimental result but difference for over ...

Development of Permanent Magnetic Traction Motors for High-speed EMUs

open access: yes, 2016
High-speed EMUs were strict with the performance and reliability, such as efficiency and power density, while traditional asynchronous traction motors had little room for improvement of performances to meet the requirements of new generation high speed railway traction system, so the permanent magnetic traction motors (PMTM) of the high-speed EMUs was ...
