The rotor is symmetrical except for the unbalanced m at radius r: U = m*r = M*e U = M*e so e = U/M = m*r/M The unbalance mass m times its radius r equals U Rotor unbalance. Divide this by rotor mass and we get e, which is a measure of unbalance that is independent of rotor mass. It is called mass eccentricity, or specific unbalance.
