ABSTRACT:
A method and apparatus for dynamically balancing a rotary member by mass compensation in first and second correction planes on the rotary member, wherein in dependence on the rotary member mass, its mass moment of inertia, the measuring speed of rotation and the spacing of the correction planes from the measuring planes, measurement value vectors which are supplied by measuring sensors in the measuring planes are turned through angles which are obtained from a respective stored family of curves produced by means of test runs. Each family of curves represents phase shifts of the measurement vectors relative to the correction vectors in the correction planes in dependence on the rotary member mass, the mass moment of inertia, the speed of measuring rotation and the spacing of the rotary member or the correction plane from the measuring plane.
