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.
