Abstract: A motor-operated compressor according to the present disclosure includes a first scroll performing an orbiting motion, a second scroll coupled to the first scroll to form a compression chamber with the first scroll and radially supporting a rotation shaft, a main housing coupled to the second scroll outside the second scroll, and coupled with a driving motor to form a motor chamber, the main housing including an opened end at one side of the motor chamber, a frame portion formed at another side of the motor chamber to axially support the second scroll, and a first bearing portion formed through the frame portion so that the rotation shaft is inserted therethrough to be radially supported, and an inverter housing coupled to the opened end of the main housing to seal the motor chamber, whereby a main frame can be easily formed and a compressor fabrication process can be simplified.

Abstract: A synthetic resin bearing and a scroll compressor (100, 200) using the same are provided. In the synthetic resin bearing as a journal bearing (122, 132, 163, 228, 234) fixed to an orbiting scroll (160, 240) or a main frame (120) and relatively rotated with respect to a rotational shaft in a scroll compressor, the journal bearing is made of a PEEK material, and a thickness t of the journal bearing is smaller than a thickness t1 with which a temperature in a contact surface thereof with the rotational shaft (143, 226) during an operation of the scroll compressor corresponds to a glass transition temperature.
