ABSTRACT:
A balancing machine is used to measure the unbalance of a rotor by obtaining a first reading representative of the vector sum of the unbalance of the rotor and an amount comprising the product of the mass of the rotor and its eccentricity relative to the axis of the balancing machine. A second reading is obtained after shifting the rotor 180.degree. relative to the balancing machine while maintaining the same eccentricity, and the second reading is then subtracted from the first to obtain a final reading representative of the true unbalance of the rotor without influence of its eccentricity relative to the balancing machine. The final reading is used to effect a true balance of the rotor, and an arrangement is provided to accomplish such balance.
