"Calculation of Position Dependent Inductances of a Permanent Magnet Synchronous Machine with an External Rotor by using Voltage Driven Finite Element Analyses";
IEEE Transactions on Magnetics, vol. 45 (2009), 3; S. 1788 - 1791.



Kurzfassung englisch:
The paper discusses finite element analyses of a skewed permanent magnet synchronous machine (PMSM) with an external rotor regarding the magnetic saliency. Since the machine is fed from a voltage source inverter (VSI), a simulation as close as possible to the regular operational behaviour is intended. Therefore, a voltage driven finite element model with a strong circuit coupling excited with the time-dependent voltages according to the space vectors of the VSI will be applied. This approach directly allows for a comparison of the numerically obtained phase currents with those obtained from measurements. Afterwards, the inductance characteristics depending on the rotor position can be evaluated from the time-dependent phase currents in order to obtain the suitability for a sensorless control algorithm.
