The subject of the invention is a method and a computer program for assessing the condition of rotating machinery connected to an electric motor, where the motor (MM) and the rotating machine (RM) comprise a drive train electrically powered from a three phase motor and said motor is connected with a computing device. The invention is characterized in that is comprises the step of classifying the condition of rotating machine (RM) connected to the electric motor (MM) of a drive train with unknown condition, by analyzing all the extracted representative features obtained from the electric signals acquired from the electric motor (MM) of said drive train, by using a trained neural network whose training was conducted by analyzing the extracted features from N different drive trains of N conditions, where said trained neural network data is stored in unit (3.5) of the computing device (CD, CD') and next generating an output vector (Z=[Z1... ZN]), wherein the vector (Z) has N elements and if the output vector (Z)
