Abstract :
A locomotive transmission study has been performed to determine the requirements and design of new three-phase traction drive components for independent bogie control on a six-axle freight locomotive. System considerations that affect locomotive high tractive effort capability and component ratings were investigated using computer models of the traction drive components. These include traction motor load sharing due to wheel-rail friction creep conditions, bogie weight shift, motor torque-speed characteristics, and wheel-diameter variations. The methodology, results and conclusions of the study are presented in detail
