Kurzfassung englisch:
For INFORM-based sensorless position estimation with conventional current sensors the current control is interrupted in certain time intervals. During the so called INFORM-measurement, definite voltage space phasors are applied to the machine and the resulting current response is measured. A suitable evaluation of the measured quantities yields the required rotor position. The basic idea of the presented paper is to minimise the INFORM-measurement with respect to its duration and its repetition rate. Combining the improved measurement sequence with a corresponding modified evaluation a high quality position estimation is obtained at significantly reduced current distortion compared to the previous measurement sequence.
