There are provided with a motor rotor ( 22 ) fixed to a turbine shaft ( 12 ) and rotating together with the turbine shaft, a motor stator ( 24 ) surrounding the motor rotor and fixed within a bearing housing ( 16 ), an inverted ( 26 ) converting a dc power into an ac power, and an inverter controller ( 28 ) controlling a frequency and a voltage of the ac power by the inverter. The inverter and the inverter controller are accommodated in a driver container ( 29 ), and are coupled to a compressor housing ( 20 ) by an insulating coupling member ( 30 ).
