Abstract
A scroll compressor includes a compression mechanism, a crankshaft, and a drive motor. The compression mechanism has a fixed scroll and a movable scroll and is configured to compress a fluid. The crankshaft has a main shaft and an eccentric portion eccentrically disposed at one end of the main shaft and coupled to a back side of the movable scroll. The drive motor has a stator and a rotor coupled to the main shaft of the crankshaft to rotate the movable scroll. At least one of the main shaft of the crankshaft and the rotor of the drive motor is provided with a weight. The weight being is arranged to balance a centrifugal force of the movable scroll during rotation, and to reduce warpage of the crankshaft caused by balancing the centrifugal force of the movable scroll.
