The present disclosure provides an electric compressor including: a rotating shaft driving a compression mechanism; a rotor in which a rotation shaft through hole into which the rotor shaft is inserted is formed; a cover member covering a longitudinal end portion of the rotor; and a stator disposed radially outside of the rotor, in which: the rotor has a plurality of slots formed to be spaced apart from each other in a circumferential direction, and permanent magnets are respectively inserted into the plurality of slots; each of the grooves has cooling holes formed at both ends of the groove, the grooves and the cooling holes being spatially spaced apart from each other; and a coolant flows through the cooling hole to cool the permanent magnet. Accordingly, cooling performance of the permanent magnets of the rotor may be improved.
本公开提供了电动压缩机,该电动压缩机包括:旋转轴,该旋转轴驱动压缩机构;转子,在该转子中形成有供转子轴插入的旋转轴通孔;覆盖件,该覆盖件对转子的纵向端部进行覆盖;以及定子,该定子设置在转子的径向外侧,其中:转子具有多个槽,所述多个槽形成为在周向方向上彼此间隔开,并且永磁体分别插入到所述多个槽中;槽中的每个槽具有形成在槽的两个端部处的冷却孔,槽和冷却孔在空间上彼此间隔开;并且冷却剂流动通过冷却孔以对永磁体进行冷却。因此,可以改善转子的永磁体的冷却性能。
