This paper presents the results of a study conducted to identify defects in MTA2 traction electric motors designed and manufactured by Softronic for LEMA 6000 kW electric locomotives.
Asynchronous traction electric motors ensure reliable operation and maintenance under the conditions specified by the designer. However, a number of stress factors cause degradation and aging, which require careful analysis of failure modes and causes, and of measures to reduce the frequency and consequences of potential defects. The operating history of these motors in traction service enables analysis of relevant operational data and of the manufacturing, assembly, and operational stages. The study addresses the proposed issue using Failure Tree Analysis (FTA) and Failure Modes and Effects Analysis (FMEA), and considers the possible defects, how they occur, their causes, detection, and measures to increase reliability and availability.
