Structure Feature of Bogie Driven Directly and the Influences on Dynamic Performance of Vehicle

Compared with the traditional bogie driven by asynchronous motor with gearbox,bogie driven directly by permanent-magnet synchronous motor has more advantages in terms of transmission without gear,structure simplified and reliability.It is obviously on structure feature that may influence the dynamic performance of vehicle.The new structure measues should be taken in order to assure the dynamic performance of vehicle.
