Abstract:
1. A rotation balance correcting method of a motor-driven supercharger, wherein the motor-driven supercharger is structured so as to accelerate and assist a rotation of a supercharger rotor in which a turbine impeller and a compressor impeller are coupled to both ends of a shaft of the motor-driven supercharger, and are integrally rotated by a built-in electric motor, wherein the method comprises the steps of: (a) rotationally driving the supercharger by the electric motor, wherein the electric motor is driven by using a dedicated motor driver that is different from an acceleration assisting motor driver supplying an electric power to the electric motor at a time of assisting the acceleration and supplies a larger electric power than a power supply of the acceleration assisting motor driver to the electric motor; (b) detecting data necessary for correcting the rotation balance of the motor-driven supercharger; and (c) correcting the rotation balance.
