Determination of inductances for pulsating current traction motor

The object of research is a pulsating current traction motor. To improve the accuracy its mathematical model, it necessary to use values parameters that are determined in experimental studies electric In particular, important model motor inductance obtained experimentally. A method proposed for calculating armature winding, main poles, additional poles and compensation winding total circuit. calculations based on results indirect measurement method, which electrical various modes power supply windings directly measured, inductances by auxiliary calculations. circuit have non-linear dependence flowing through them. difference study measurements required carried out over entire range operating currents windings. essence technique measure active as well circle whole when they supplied with alternating current. According losses phase displacement, corresponding reactive determined, help calculated. Approbation methodology conduction an NB-418K6 (country origin Russia), used locomotives VL80T VL80k series Russia). scheme measuring proposed. graphical dependences current, built basis calculations, confirmed hypothesis about nonlinear these For further application simulation operation NB-418K6, polynomial approximation was performed.
