FIELD: measurement and testing technology. SUBSTANCE: method may be used for determination of inertia moment I relative to axis of rotation and turning of solid bodies different in form. Article under test is secured on active rotor of AC motor. Forced sustained mechanical oscillations are created by means of DC source and controllable AC source connected to stator windings of electric motor. Frequency and amplitude of oscillations are measured in electromechanical system thus formed. Obtained results are used for calculation of value I sought for. EFFECT: reduced labour intensity of experiment, simplified construction of electric drive and enhanced accuracy of inertia moment I determination. 1 dwg
