Abstract
A motor-operated compressor includes a housing and a driving motor disposed in an inner space of the housing. The driving motor includes a stator and a rotor. A rotary shaft is coupled to the rotor. A first scroll is provided on one side of the driving motor and the rotary shaft passes through and is rotatably coupled to the first scroll. A second scroll is coupled to the first scroll and an eccentric part of the rotary shaft passing through the first scroll to form a compression chamber between the first scroll and the second scroll. A frame is provided opposite to the driving motor with the first scroll and the second scroll interposed therebetween and configured to axially support the second scroll and radially support one end of the rotary shaft passing through the second scroll.
