For the study of digital twin models, this paper analyzes the electromagnetic characteristics, mechanical characteristics, thermodynamic characteristics, and mutual coupling relationship of the other-excited DC motor, and constructs a mathematical model of ”electric-mechanical-thermal” integration suitable for digital twin technology. The model is built under the experimental data parameters and experimental information of the solid DC motor, which increases the generality, accuracy and timeliness of the model. The digital twin simulation system is built and used in simulation experiments on high-speed motor accidents using 3dsMax, Unity3D, and C#. The results show that the digital twin model is reasonably constructed, and the operation is stable and reliable in the built digital twin system, which can well map the various experimental data conditions of the real DC motor, and the simulation experiment is well applied, also solve the barrier that the real experiment can’t conduct experimental operation on the high-speed motor accident, the experiment can be conducted anytime and anywhere, which is conducive to improving the efficiency, safety and accuracy of engineering teaching and saving resources.
