摘  要：本文根据某地铁使用的牵引电机作为研究对象。为确保地铁通过电磁兼容测试，通过Ansoft Maxwell仿真软件完成牵引电机的精确建模，模拟牵引电机运行状态，得出周围磁场分布云图，并通过傅里叶变换得出频谱分析图。 关键字：电磁兼容；牵引电机；电磁辐射 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 tract[登陆后可查看全文]
