The utility model discloses a permanent magnet synchronous motor rotor with a non-uniform structure, which comprises a rotor iron core, a plurality of holes are arranged on the rotor iron core, the plurality of holes form an asymmetric structure, and the same effect of using a balance block to balance weight can be achieved only by adjusting the position, the size and the depth of the holes to cause the difference of weight and center of mass. A balance block on the rotor or the crankshaft is omitted, procedures are reduced, cost is lowered, space is saved, and meanwhile the risk that the balance block falls off is avoided. 本实用新型公开了一种非均匀结构的永磁同步电机转子，包括转子铁芯，所述转子铁芯上开设有若干孔，所述若干孔形成非对称结构，只需调整开孔的位置、大小、深度，造成重量质心差异，就可以达到使用平衡块配重的同等效果，取消了转子或者曲轴上的平衡块配置，减少工序，降低成本，节省空间的同时也避免了平衡块脱落的风险。
