Synchronous reluctance machines with internal flux barriers can be designed to have a high saliency. Permanent magnets inserted into the rotor flux barriers considerably increase the effective saliency. The parameter of a 5 kW machine with a maximum speed of 8000 rpm for an application in a position-sensorless drive with a wide field-weakening range is evaluated by means of nonlinear finite element analysis. In addition to the normal reluctance machine, the machine with the considered additional permanent magnets is analyzed. The comparison of the characteristics of both the usually reluctance machine and the permanent magnet assisted machine clearly shows the improved performance due to the interior permanent magnets. The main focus of the performed research is on the machine behavior in the control scheme of the drive. not assigned KP: Partner aus der Industrie (anonym)
