Alstom’s Chinese joint venture, Alstom NUG Propulsion System Co. (ANP) has successfully applied its silicon carbide (SIC) and permanent magnet motor propulsion system (PMM) on a demo train on Chengdu Line 7.
This was the first time that this type of traction system has been introduced in China, combining a complete silicon carbide traction converter and a permanent magnet synchronous motor.
Following this demonstration, the train has now begun passenger operations.
Alstom said this project marked the start of a new chapter in energy conservation in the rail transit industry, as the use of SIC and PMM technologies would save 30% of energy in train traction.
This is thanks to advanced technologies such as silicon carbide power devices with high-frequency, high-junction temperature and low loss, as well as high-efficiency permanent magnet synchronous motors.
“Thanks to the recognition and trust of Chengdu Metro, the success of this project represents a new milestone in Alstom's development in China. In the future, we will work with ANP to continuously track the operation of the first silicon carbide permanent magnet motor demonstration project, innovate new technologies and processes to save energy and reduce consumption.”
