ABSTRACT:
A method and device for detecting the motor position of a DC motor includes evaluating the back-induced voltage of non-energized motor windings of the motor only during predetermined time durations whose temporal position and duration are derived from drive signals for half-bridge circuits that are connected to the motor windings.
