Abstract: A motor-operated compressor includes a compression part including a fixed scroll and an orbiting scroll that form a compression chamber configured to compress fluid by an orbiting motion of the orbiting scroll relative to the fixed scroll. A motor part is disposed at one side of the compression part, and configured to generate a drive force to cause the orbiting scroll to make the orbiting motion. A rotary shaft is connected to the motor part and the orbiting scroll to transmit the drive force generated by the motor part to the orbiting scroll. A main frame is disposed between the compression part and the motor part in an axial direction of the rotary shaft, and configured to support the fixed scroll in the axial direction of the rotary shaft. A discharge chamber is formed between the fixed scroll and the main frame, and fluid discharged from the compression part passes through the discharge chamber to outside of the motor-operated compressor.
