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.
