The invention provides an urban rail vehicle multi-phase traction system and an urban rail vehicle thereof. The system comprises a direct-current power supply module, a plurality of traction inversionmodules and a multi-phase motor module, wherein the input ends of the plurality of traction inversion modules are respectively connected with the direct-current power supply module, and the output ends of the plurality of traction inversion modules are respectively connected with each phase of motor of the multi-phase motor module, so each traction inversion module respectively controls the powersupply input of each phase of motor of the multi-phase motor module. The urban rail vehicle is driven by the multi-phase motor, each traction inverter controls the power input of the motor of each phase, once a certain phase goes wrong and blocks pulses, other phases can still form a circular magnetic field, and the situation that the power output of the shaft is completely cut off, and consequently the performance of the vehicle is sharply reduced is avoided.
本发明提供一种城轨车辆多相牵引系统及其城轨车辆。本发明系统,包括:包括:直流电源模块、多个牵引逆变模块以及多相电机模块;多个所述牵引逆变模块的输入端分别与所述直流电源模块连接,多个所述牵引逆变模块的输出端分别与多相电机模块的每相电机连接,实现每个所述牵引逆变模块分别控制所述多相电机模块每相电机的电源输入。本发明城轨车辆采用多相电机驱动,每个牵引逆变器分别控制每相电机的电源输入,一旦某相出现问题封锁脉冲,则其他相依然可以形成圆形磁场,不会导致该轴的动力输出全部切除,造成车辆性能急剧下降。
