Abstract
A method of balancing a core assembly of a turbocharger. The core assembly may include a rotor assembly having a compressor wheel and a turbine wheel connected for common rotation by a shaft. A first bending critical speed of the rotor assembly may be determined. The core assembly may be mounted in a balancing machine. A drive source may be engaged with the core assembly to impart rotation. The rotor assembly may be rotated at an initial phase speed that is between approximately 5500 revolutions per minute and the first bending critical speed. A state of imbalance of the rotor assembly may be determined at the initial phase speed.
