Abstract :
Synchronous reluctance machines with internal rotor flux barriers can be designed to have a high saliency. Permanent magnets inserted into the rotor flux barriers considerably increase the effective saliency. The parameters of a 5 kW machine with a maximum speed of 8000 RPM for an application in a position-sensorless drive are evaluated by means of nonlinear finite element analyses. The comparison of the characteristics of both the conventional reluctance machine and the permanent magnet assisted reluctance machine shows the improved performance due to the permanent magnets.
