A large number of machineries, such as long-wall shearer and tunnel boring machine, contain the multi-stage gear transmission system with planetary gears driven by electric motor, whose electromechanical characteristics have significant effect on the performance of machineries. Therefore, a test rig of this kind of transmission system is established, and the electromechanical dynamic model is also constructed for it, including the electric motor and the gear transmission. Moreover, to obtain more accurate simulation results, a method is proposed to estimate the equivalent damping value of the gear transmission system in the aspect of energy based on the testing data. Next, the electromechanical dynamic characteristics, including the motor current and the internal load of the gear transmission, are investigated by experiment and simulation under shock and step load to provide some guidance for improvingthe dynamic performance and monitoring the working state. The electromechanical dynamic modeling method is also well validated by the comparison between the simulating and test results.
