Calculation of Windings Differential Inductances of Electrical Devices in Mathematical Models with a Total Magnetic Flux

The calculation of differential electromagnetic parameters (differential inductances and mutual inductances of windings) of electric machines and electromagnetic devices based on the mathematical models of their magnetic circuits with a total magnetic flux is proposed. These parameters are determined using the geometric dimensions and design features of the devices, the main magnetization curve of the magnetic core material and the winding currents.
