Abstract :
This contribution investigates the influence of magnetic saturation on the sensorless control of IPM synchronous motors. An extended analytical motor model is introduced that covers magnetic anisotropies and describes the fundamental wave as well as the harmonic characteristics. Simulation results are compared to actual measurements on a servo drive.
