This study presents an analytical method to calculate the dynamic performances of scroll compressor with various characteristies of motor. For same motor's speed with variable motor torque, even if motor torque is variable, mechanical efficiencies have the same level and the in most mechanical loss is in crankpin. In case of various motor's speed, as motor's speed increases, friction losses of two journal bearing increase largely without merease of gas. compression. energy So mechanical efficiencies are decreased when the motor's speed is high.
