Abstract
A method for determining a saturation characteristic of a synchronous reluctance machine includes applying with a pulse inverter a voltage sequence to a stator of the synchronous reluctance machine, wherein the voltage sequence introduces stator fluxes and is applied such that torques acting on a rotor of the synchronous reluctance machine cancel each other out during the application of the voltage sequence. Electrical currents resulting from the stator fluxes are measured and the saturation characteristic is determined based on the stator fluxes and the measured electrical currents.
