Abstract
An electric compressor including: a housing; a compression mechanism which compresses refrigerant within the housing; and a motor which provides a driving force to the compression mechanism. The motor includes a stator supported on the housing and a rotor rotated by interaction with the stator. The rotor includes a core in which a magnet is installed, a balance weight installed at an end of the core to adjust the rotation balance of the rotor, a cover that covers the core between the core and the balance weight, and a refrigerant flow path through which the refrigerant sequentially flows through the balance weight, the cover, and the core. As a result, it is possible to suppress the performance degradation and the loss of operational capability of the motor by suppressing the temperature rise of the magnet provided in the rotor of the motor and the consequent demagnetization phenomenon.
