Electromagnetic Susceptibility Test and Analysis of Brushless DC Motor

With the development of electronic technology, the electromagnetic environment becomes more and more complex, leading to increasing importance of the anti-interference ability of electronic equipment. In this paper, a conductive susceptibility test platform was built, and the brushless DC motor was selected to be the device under test. This paper first introduces the working principle of the brushless DC motor. Then the conductive susceptibility of the motor is tested with the speed change as the sensitive phenomenon. Finally, the electromagnetic sensitive threshold and the susceptibility mechanism of the motor is analyzed through the test result.
