Currently, the company is buying several electric locomotives from abroad in order to ensure the continuity of train movement under the conditions of Uzbekistan Railways JSC. The torque electric motors in it are asynchronous motors, and they cause several malfunctions in the electric motor as a result of electromagnetic braking. In this article, we will get acquainted with the analysis of exactly such reasons.
