The electromechanical model for analyzing the dynamic load distribution of the electronic system and the mechanical subsystem of the diesel locomotive with asynchronous traction drive under unsteady working conditions is introduced. The traction performance of the transmission is compared with that of the adopted The structure and working principle of direct torque control system of induction motor are described in detail. At the same time, it is pointed out that the system can make full use of potential adhesion when starting and accelerating of diesel locomotive under various road conditions Conditions, to maximize the ultimate traction, as well as the use of diagonal rod bogies can reduce the axle motor overload current situation.
