  • Method for determining the angular position of the rotor of a mechanically commutated d.c. servo motor
    Patent number: 8222843
    Abstract: Method for determining the angular position of the rotor of a mechanically commutated DC servo motor (5), which is arranged in the transverse branch of a bridge circuit, and the armature current of which is preset by an electromechanically activated switching device (28), —with a control and analysis unit (17) which analyzes the current ripple (3) present in the armature current (2) and attributable to the mechanical commutation, characterized in that—from each switch contact (6, 7) of the switching device (28), a contact-voltage feedback signal (9, 10) is fed back to the control and analysis device (17) by means of a feedback circuit (20), and in that the control and analysis unit (17), by using the at least one contact-voltage feedback signal (9, 10), determines a contact vibration time interval (4) and performs an estimate of current ripple (3) during this contact vibration time interval (4), during which an analysis of the current ripple due to contact vibrations which are caused by a switching process of
