The Identification of Selected Imperfections of Electric Traction Motors
Journal Title: Logistics and Transport - Year 2013, Vol 19, Issue 3
Abstract
Electric traction motors of rail vehicles operate in very harsh conditions. This is due to their varying load and power fluctuations, as well as their exposure to high humidity, excessive shocks, dust and changing ambient temperature. These conditions can lead to the non-operational state of motors in operation which should be identified as soon as possible. This requires building the mathematical model of a traction drive system, which enables the full simulation of its work in real time. It also requires interference in the construction of the electrical system that allows for measuring the values of the relevant diagnostic features. The measurements of these features and their comparison to the values obtained from the mathematical model with the use of a multi-valued evaluation constitute the basis for the formulation of the operational diagnoses of traction motors.
