摘要：The invention relates to methods and devices for monitoring and correcting asensorless rotor position detection in permanently excited motors, comprising a control
device and a current converter. The invention is especially characterised in that theambiguity of the rotor position determined from the inductance ratios of the motor, inpermanently excited motors, can be resolved in a simple manner without a sensor, and adefectively determined angle can be corrected as required. To this end, during theoperation of the motor, the rotor position is detected by means of an inductance-baseddetection device. Furthermore, the rotor position is monitored in relation to theambiguity of the inductance-based signals by means of a monitoring/correcting device,and where necessary, an occurring angle error corrected, the currents in the motor beingmodified.
