ABSTRACT:
Method of balancing an electrical machine rotor comprising starting the liquid cooling system of the rotor winding formed of parallel hydraulic branches arranged on the body of the rotor, monitoring the variables of the cooling conditions of said branches, with the liquid cooling system under operation, for determining temperature asymmetry which leads to heat unbalance of the rotor, and altering hydraulic resistance in said branches so that the proportion of said variables provide the same magnitude of overheating of the liquid at least in each pair of the diametrically arranged branches of the cooling system.
