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=[Z 1 ...Z N ]), wherein the vector (Z) has N elements and if the output vector (Z) has only one element having value equal to 1 and the rest of elements values are equal to 0, determining the index (i) of the element with the value equal to 1, which index (i) indicates that the condition of the drive train under analysis is equal to the i th Condition of the N available known drive train conditions. |
