The embodiment of the invention provides a rotor assembly, a permanent magnet synchronous motor, a traction system and a vehicle. The rotor assembly comprises a rotor iron core which is provided with a plurality of permanent magnet grooves which are uniformly distributed along the circumferential direction; the permanent magnets are arranged in the permanent magnet grooves; the plurality of magnetic conductive blocks are arranged corresponding to the plurality of permanent magnet grooves, and each magnetic conductive block is arranged on one side, close to the rotating shaft, of the corresponding permanent magnet groove along the radial direction; the magnetic conductive block is configured to move between a first position close to the permanent magnet groove and a second position far away from the permanent magnet groove so as to adjust the magnetic field distribution of the rotor assembly.

    本申请实施例提供了一种转子组件、永磁同步电机、牵引系统及车辆。该转子组件包括:转子铁芯,具有沿周向均布的多个永磁体槽;永磁体,设置在永磁体槽内;多个导磁块,与多个永磁体槽对应设置,每个导磁块沿径向设置在对应的永磁体槽靠近转轴的一侧;导磁块被配置为在靠近永磁体槽的第一位置和远离永磁体槽的第二位置之间进行移动,以调节转子组件的磁场分布。
