New technological diagnostics algorithm of required electric motors

The paper illustrates one of the directions determining the improvement of the quality of the ship electrical equipment technical condition control and diagnostics. We consider a new algorithm to diagnose the technical condition of propulsion motors based on the representation of a propulsion motor as a variable object the operation of which consists in the object structure transformation under the influence of various factors. The parameters of propulsion motors diagnostics are determined. Functional and mathematical models for diagnosing propellers have been created. The developed algorithm for propulsion motor diagnostics allows detecting faults with a given diagnosis depth. This algorithm can be used as a part of expert systems to monitor the technical condition of ship electric power plants. A complex approach to the construction of an algorithm for the propulsion motors technical diagnostics of based on the logical diagnosis model is proposed. A distinctive feature and novelty of the proposed algorithm for propulsion motor diagnostics is that it allows one to take into account the mutual influence of diagnostic features on the object state and assess the technical condition of any propulsion motor from consistent methodological positions.
