The invention discloses a traction system and a traction motor, and relates to the field of motor drive.The traction system comprises an inversion module, the input positive end of the inversion module is connected with the first end of a positive pantograph, the second end of the positive pantograph is connected with the positive electrode of a power line, and the input negative end of the inversion module is connected with the first end of a negative pantograph; the second end of the cathode pantograph is connected with the cathode of the power line and is used for converting the direct-current voltage output by the power line into alternating-current voltage to supply power to the traction motor; the first end of the load contactor is connected with the output end of the inversion module, and the second end of the load contactor is connected with the power supply end of the traction motor. The inverter module is arranged to convert direct current output by the pantograph, and converted alternating current supplies power to the traction motor. Meanwhile, the load contactor is arranged, the permanent magnet traction motor and the inverter are effectively disconnected when necessary, further expansion of faults is avoided, and the effect of counter electromotive force generated by the permanent magnet traction motor is avoided.

    本发明公开了一种牵引系统及牵引电机,涉及电机驱动领域,包括逆变模块,逆变模块的输入正端与正极受电弓的第一端连接,正极受电弓的第二端与电源线的正极连接,逆变模块的输入负端与负极受电弓的第一端连接,负极受电弓的第二端与电源线的负极连接,用于将电源线输出的直流电压转换为交流电压为牵引电机供电;负载接触器,负载接触器的第一端与逆变模块的输出端连接,负载接触器的第二端与牵引电机的供电端连接。设置了逆变模块对受电弓输出的直流电进行转换,转换后的交流电为牵引电机供电。同时设置了负载接触器,在必要的时候将永磁牵引电机与逆变器有效地断开,避免故障的进一步扩大,以实现避免永磁牵引电机产生的反电势的影响。
