Abstract

A motor-driven compressor includes a compression mechanism compressing and discharging fluid, an electric motor driving the compression mechanism, a drive circuit controlling the electric motor, a drive circuit chamber accommodating the drive circuit and a hermetic sealing inspection port that allows the drive circuit chamber to be in communication with the outside thereof. The hermetic sealing inspection port includes a valve opening and closing the hermetic sealing inspection port. The drive circuit chamber can be pressurized or depressurized through the hermetic sealing inspection port. The hermetic sealing inspection is conducted by connecting an outside fluid machine to the hermetic sealing inspection port through a detachable tube. The fluid machine is operated so as to depressurize or pressurize the drive circuit chamber through the hermetic sealing inspection port. The pressure in the drive circuit chamber is measured by a pressure meter provided in the tube.
