Permanent magnet synchronous machines with an external rotor nowadays gain in significance for high performance electrical drive systems such as with hybrid electric vehicles. With these applications, the machine will operate in a wide speed range and on the other hand with very fast changing loads in both motor and generator operational modes. In order to achieve a robust machine design, a position-sensorless...
This 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 behavior is intended. Therefore, a voltage-driven finite element model with a strong circuit coupling excited with the...
