Conducted Electromagnetic Disturbance Prediction of Electric Power Robot Motor Drive System

With the continuous development of artificial intelligence, electric robots in the power grid can replace manual work in some dangerous environments and conditions with high accuracy requirements. The electromagnetic compatibility of power robots in complex electromagnetic environments is particularly important for safety and reliability, and is one of the key indicators for the practical application of power robots. In the motor drive system of power robots, due to the rapid opening and closing of switching devices, many pulses are generated, and these pulse signals can cause oscillations and generate non-negligible electromagnetic disturbance, which seriously affects the normal operation of its own equipment and adjacent electrical equipment. In this paper, we analyze the conduction disturbance sources and disturbance propagation paths of motor drive system, propose a modeling and prediction method for conduction disturbance of motor servo drive, and conduct experimental verification of simulation results, and make a prospective study on the suppression method of conduction disturbance. The test shows that the method can effectively predict the conducted disturbance waveform of electric power robot motor drive system, which is an important guidance for the solution of electromagnetic disturbance problem of electric power robot drive system.
