Abstract
A scroll compressor has a closed vessel in which a compression mechanism having orbiting and stationary scroll elements in engagement with each other is accommodated. A crankshaft is coupled with the orbiting scroll element and rotatably supported by a crank bearing. The crankshaft is rotated by an electric motor having a stator and a rotor so that the orbiting scroll element may orbit relative to the stationary scroll element. A plurality of balance weights are provided for maintaining static and dynamic balances of rotary elements including the orbiting scroll element, the crankshaft, and the rotor. The static and dynamic balances are calculated using at least a clearance between the crankshaft and the crank bearing.
