The paper proposes a method for determining the leakage in the gate of an electric drive armature by sound and ultrasonic signals using the Shannon and approximation entropy indices. The results of equipment diagnostics in laboratory and industrial conditions are presented. The results indicate the possibility of using entropy indicators as sensitive diagnostic features.
