Test and Analysis of Electromagnetic Sensitivity Mechanism Characteristics of Motor Control System

With the wide application of motor control systems, the performance of the motor has become more stable. However, in the face of increasingly complex electromagnetic environment, the electromagnetic compatibility problems of motor control systems become more and more severe. This article takes the motor control system composed of the stepping motor as the research object. With experimental demonstration, the electromagnetic sensitivity mechanism of the stepper motor control system under typical interference signals is studied, and the electromagnetic sensitivity threshold law and sensitivity model of the stepper motor control system are proposed. This sensitive model is related to the length of the interference time and the power of the interference signal.
