经对交直传动电力机车辅助系统劈相机电源供电进行分析,其三相电源不称度没法从原系统得根本解决。对无刷永磁直流电动机的结构特点及技术优势进行分析阐述,无刷永磁直流电机及控制系统应用于交直传动电力机车辅助系统,具有成本低、节能、占用机车空间少、重量轻、故障低、维修方便等优势。
After analyzing the power supply of the split-camera power supply system of the AC-DC power locomotive auxiliary system, the three-phase power supply can not be solved fundamentally from the original system. The structural characteristics and technical advantages of brushless permanent magnet DC motor are analyzed and explained. The brushless permanent magnet DC motor and control system are applied to the auxiliary system of AC-DC electric locomotive, which has the advantages of low cost, energy saving, less space occupied by the locomotive, light weight, fault Low, easy maintenance and other advantages.
