城市轨道交通列车动力系统
摘要：
本发明提供一种城市轨道交通列车动力系统，设置在城市轨道交通列车的动车中，所述系统包括：多个永磁同步牵引电机和多个控制子系统；所有的永磁同步牵引电机都设置在所述动车的转向架上，为所述动车提供动力；永磁同步电机的数量与控制子系统的数量相同；一个控制子系统只为一个永磁同步牵引电机供电，一个永磁同步牵引电机只接受一个控制子系统的供电。本发明可以实现将永磁同步牵引电机应用于城市轨道交通列车的动力系统中。
摘要（英）：

The invention provides a power system of an urban railway transit train, which is arranged in a motor car of the urban railway transit train. The power system comprises a plurality of permanent magnet synchronous traction motors and a plurality of control subsystems. All of the permanent magnet synchronous traction motors are arranged on a bogie of the motor car and used for supplying power for the motor car, and the amount of the permanent magnet synchronous motors is the same as that of the control subsystems. One control subsystem only supplies power for one permanent magnet synchronous traction motor, and one permanent magnet synchronous traction motor only receives the power supply from one control subsystem. By adopting the invention, the permanent magnet synchronous traction motors can be applied to the power system of the urban railway transit train.
