Abstract: A motor-operated compressor includes a casing having an inner space in which a driving motor, an orbiting scroll and a fixed scroll are accommodated, and a controller provided outside the casing. The casing includes an intake hole formed at a side adjacent to the controller and an exhaust hole formed at a side adjacent to the fixed scroll on the basis of the driving motor. The casing includes a communication passage formed between the casing and a stator of the driving motor, such that a refrigerant introduced into the inner space through the intake hole is introduced into the suction chamber through the driving motor. A back pressure space supporting the orbiting scroll is sealed by oil. The stator has teeth on its inner circumferential surface and protrusions on its outer circumferential surface, each protrusion being located within a width range of each tooth.
