Analysis of permanent magnet traction system technology for urban rail transit
浅析城市轨道交通永磁牵引系统技术

摘要

随着城市生活节奏的加快，在大城市的大客流等地区对城市轨道交通提出了更高要求，快起快停、节能降耗、高效率已经成为城市轨道交通牵引系统的发展趋势，既有的异步电机已经无法满足更加严峻的牵引系统需求。因此，永磁牵引系统应运而生，本文对永磁牵引系统分析、对比，研究永磁牵引系统对城市轨道交通发展的影响。

Abstract

With the acceleration of urban life rhythm, higher requirements are put forward for urban rail transit in areas such as large cities with large passenger flow. Quick start and quick stop, energy saving and consumption reduction, and high efficiency have become the development trends of urban rail transit traction systems. Existing asynchronous motors have been unable to meet the more severe demands of traction systems. Therefore, the permanent magnet traction system came into being. This paper analyzes and compares the permanent magnet traction system, and studies the influence of the permanent magnet traction system on the development of urban rail transit.
