ANALYSIS OF RELIABILITY INDICATORS OF MARINE ELECTRIC MOTORS USED IN MODERN SHIP EQUIPMENT

Abstract

The article provides an analysis of the reliability indicators of marine electric motors (EM) used in modern marine equipment. The reliability and efficiency of the ship's electric drive (ED) is ensured by a system of measures, where along with design solutions, an important place is given to the maintenance and maintenance of the operational characteristics of electric drives during operation. On ships, electrical equipment must withstand such factors as constantly manifested heel and trim, vibration and shock effects, overheating and high humidity of the air, the inability to quickly deliver the equipment to the repair base. Consequently, the reliability of ship electrical installations as repairable is regulated by special requirements. The subject of the research is the characteristic damage of marine electric motors used in modern electric drives. Indicators of the actual level of reliability of modern ships and their component equipment are given. The dependence of the failure of ship electrical equipment on operating conditions, materials used, operating modes, and more is considered. Conclusions are drawn about methods of increasing the reliability of specific types of electric motors and about the prospect of using various electric motors in modern marine electric drives. For the effective implementation of integrated diagnostics of asynchronous electric drives, it is necessary to solve a number of related problems, which will significantly increase its efficiency and ensure the required level of reliability and safety of ship electrical equipment. The usage of integrated diagnostics opens up broad prospects for the creation of intelligent control systems for complex control systems operating in conditions of incomplete information.
