Most tractive electric rolling stock units are equipped with pulsed current motors that serve as traction engines. In particular, these are the alternating current electric locomotives, series VL-80Т and VL-80K, equipped with NB-418-K6 engines. In addition, pulsed current motors are used in the electric locomotives ChS4, VL8, VL40, VL60, 2EL5K, as well as industrial traction units OPEL1A(M). The study of dynamic processes that occur in the traction drive of an electric locomotive requires the construction of an adequate mathematical model. The traction drive of the AC electric locomotive includes such functional units as a traction transformer, a rectifying unit, a smoothing reactor, as well as traction engines. The most complex element in an electric locomotive traction drive is traction motors. Building a mathematical model of the traction motor causes certain difficulties. First, these difficulties are associated with Copyright © 2020, S. Goolak, S. Sapronova, V. Tkachenko, I. Riabov, Y. Batrak
