摘  要：本文根據某地鐵使用的牽引電機作為研究對象。為確保地鐵通過電磁兼容測試，通過Ansoft Maxwell仿真軟件完成牽引電機的精確建模，模擬牽引電機運行狀態，得出周圍磁場分布云圖，并通過傅里葉變換得出頻譜分析圖。 關鍵字：電磁兼容；牽引電機；電磁輻射 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[登陸后可查看全文]
