FIELD: electromechanical engineering; synchronous electrical machines. SUBSTANCE: method is based on checking core compressive force for compliance with desired value and includes periodic measurements of controlled variable, its comparison with desired value, angle of lag of core strain axis from vector of core-disturbing force measured while machine is running being used as controlled variable; value of this parameter measured when machine was first placed in operation is used as desired value; in the process angle of lag of core strain axis from vector of core disturbing force compared with desired value points to reduced compressive force. EFFECT: facilitated procedure. 1 cl, 3 dwg
