(54) Motor-driven compressor


(57) A motor-driven compressor includes an electric motor (23), a compression mechanism (32), which compresses gas by being driven by the electric motor (23), and a body (KT) accommodating the electric motor (23) and the compression mechanism (32). The motor-driven compressor includes a motor control section (51), which drives the electric motor (23) by controlling power supply to the electric motor (23), a vibration control section (52), which generates a waveform in a phase opposite to the waveform of vibration predicted to be generated in the body (KT) due to the driving of the electric motor (23), and a vibration applying device (45a-45c), which is located on the body (KT) and applies vibration in the opposite phase generated by the vibration control section (52) to the body (KT).
