The Application of the Duality of Equivalent Circuits to Modelling Cylindrical Solid-Iron Rotors of Synchronous Machines at Asynchronous

ABSTRACT

By means of the duality of magnetic and electric equivalent circuits, an equivalent circuit is derived for the machine with slotted solid-iron rotor at asynchronous speeds. All impedances are calculated from geometrical data. The saturation, the magnetic field in slots and the impedance of the rotor ends are taken fully into consideration.
