Abstract
A method for effecting a measurement of the unbalance of a small weight rotor body such as a impeller or turbine wheel for a turbo-charger in an internal combustion engine. A shaft, on which the rotor body is inserted and which is on both ends thereof supported on a pair of bearing units, is rotated while the rotor body is held on the shaft under an elastic frictional force. The unbalance is at every angular position of the rotor body measured during the rotation of the shaft.
