(EN) The invention discloses a rotor assembly and a motor. The rotor assembly comprises a rotor core provided with a shaft hole; a rotating shaft fixedly disposed in the shaft hole; a magnetic ring arranged around the rotor core and formed by successively splicing a plurality of split arc magnets end to end; and at least two locking rings used for clamping the magnetic ring to the outer circumferential surface of the rotor core and arranged at intervals in the axial direction of the magnetic ring. The stability between the magnetic ring and the rotor core can be improved.
(ZH) 本发明公开一种转子总成和电机，其中，转子总成包括：转子铁芯，所述转子铁芯设有轴孔；转轴，固设于所述轴孔；磁环，环设于所述转子铁芯，且由分体的多个弧形磁体依次首尾拼接而成；以及锁紧环，至少设有两个，该两个锁紧环均用以将所述磁环紧箍在所述转子铁芯的外周面，且该两个锁紧环在所述磁环的轴向方向上呈间隔设置。本发明的技术方案能提高磁环与转子铁芯之间的稳固性。
