Abstract: Traction Motor, used by one subway, as the research object in this paper. To ensure the subway pass the EMC tests, it builds exact modeling of traction motor through the Ansoft Maxwell simulation software, simulating running status of traction motor to work out the surrounding magnetic picture, and through Fourier transform
