Abstract: A compressor includes a first scroll and a second scroll engaged with the first scroll for performing an orbiting motion relative to the first scroll to form a compression chamber along with the first scroll. A stator is disposed at one side of the second scroll and includes a stator core. A rotor is rotatably disposed inside the stator core, and includes a rotor core. A rotary shaft has one end portion eccentrically coupled to the second scroll and the other end portion coupled to the rotor core. The rotor core is formed with at least one space portion axially recessed into the rotor core.

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.
