ELECTRIC COMPRESSOR

摘要

A motor-driven compressor includes a housing (10), a rotary shaft (21), a compression mechanism (15) and an electric motor (6). The compression mechanism (15) is disposed in the housing (10) and compresses refrigerant flowed through the suction port into the compression mechanism and discharges the refrigerant through the discharge port. The electric motor (6) is disposed in the housing (10) and drives the rotary shaft (21) to rotate to drive the compression mechanism (15). The electric motor (6) includes a rotor (22) fixedly mounted on the rotary shaft (21) and a stator (23) fixed to the housing (10). The rotor includes a permanent magnet (31) and a compressor interior environment improvement agent (32) containing at least one of an absorbent for absorbing moisture and a neutralizer for neutralizing acid.
