[Abstract]
The increasing speed grade of electric multiple unit (EMU) requires more power, lighter weight and higher efficiency of traction motor. The parameters selection and structure design of permanent magnet traction motor of highspeed EMU are studied, and the simulation analysis and calculation are carried out. In the existing installation space, a permanent magnet traction motor with higher speed and higher power density is designed to meet the operation requirements of high-speed EMU.
