A rotation is corrected by rotationally driving a supercharger rotor (a turbine impeller (2), a compressor impeller (6) and a shaft (12)) by an electric motor (18) in a state of detaching a turbine housing (4) and a compressor housing (8), and detecting data necessary for correcting the rotation inbalance of a motor-driven supercharger (10). Further, the electric motor (18) is driven by using a dedicated motor driver (27) supplying a larger electric power than a power supply of an acceleration assisting motor driver. |
