Abstract
A mathematical model of a synchronous reluctance machine with independent regulation along the excitation line is presented. The electromechanical converter unit is presented as a system with distributed parameters and designed by the finite element method, while the semiconductor converter is approximated with a continuous dynamic element. The case of regulated induction electric drives is used to show by statistical methods that the results produced by the calculation according to the proposed mathematical model at loads from 0 to M N are close to the figures calculated using common calculation procedures. It is shown that, because of the very roughly considered saturation of the magnetic system, it is incorrect to use common mathematical models in the design of induction electric drives in the critical and supercritical torque regions. For this reason, the developed mathematical model can also be used in the design of common electric drives in the torque overload area.
