Abstract: An electric compressor including: a rotating shaft configured to drive a compression mechanism; a rotor configured to have a rotating shaft through-hole into which the rotating shaft is inserted; a cover configured to cover a longitudinal end of the rotor; and a stator configured to be installed on a radially outer side of the rotor. A plurality of slots into which a permanent magnet is inserted is formed to be spaced apart from each other in the rotor in a circumferential direction of the rotor. A cooling hole is formed in both ends of the slot, and the slot and the cooling hole are spatially separated. Refrigerant flows into the cooling hole and cools the permanent magnet. Accordingly, it is possible to improve the cooling performance of the permanent magnet.

Abstract: The present disclosure relates to a 3-phase connector integrated stator and an electric compressor including the same. The 3-phase connector integrated stator includes: a stator including a plurality of teeth formed to extend from a cylindrical core, insulators coupled to the core and the teeth so as to surround outer sides of the core and the teeth, and coils wound on outer sides of the insulators at the respective teeth; a motor cover coupled to an upper insulator in a central axis direction of the stator and having a connector coupling part protruding upwardly from an upper plate; and a 3-phase connector inserted into and coupled to the connector coupling part of the motor cover and having connection pins connected to 3-phase coils of the stator. Therefore, the 3-phase connector may be easily assembled to the stator, and the connector pins may be easily assembled to the 3-phase connector.
