Abstract

Nowadays, it becomes important to solve the problem of improving mathematical models of AC electric machines in order to clarify the analytical description of transients taking into account the active resistance in the stator winding. The use of frequency characteristics will improve the accuracy of determining the design parameters of induction motors at the design stage. In this case, taking into account the active resistance of the stator winding makes it possible to determine with sufficient accuracy the characteristics of the engine in the starting modes.
