As a main tractive system of the high speed train, a traction motor is highly required stabilization and reliability for passenger safety and needed a design of lighter weight with compact size for high speed operation. The design technology of the traction motor was developed through the G7 project and verified it by performing strength analysis of rotor and frame which are the main parts of the mechanical design and confirmed by evaluating heat stabilization of the forced ventilation cooling method. The high speed train driven by the developed traction motor could successfully run at the target speed. 350 ㎞/h in the Test Driving on December, 2004, and it is running today for its commercialization in the near future.
