Abstract
A motor-operated compressor includes a compression unit including a compression chamber formed by a plurality of scrolls engaged with each other. The compressor includes a rotation shaft having one end coupled to one of the scrolls and a rotor coupled with another end of the rotation shaft. The compressor includes a stator radially separated from the rotor by a predetermined gap. The compressor includes a casing having a motor chamber. The stator is inserted in the motor chamber and divides the motor chamber into a first space and a second space. The casing includes an inlet port coupled to the first space to guide a refrigerant toward the motor chamber. The casing also includes a suction guide passage coupled to the second space to guide the refrigerant sucked through the inlet port toward the compression unit. A communication passage portion in the rotation shaft communicates the first and second spaces.
