Circuit arrangement for determination of rotational angle position of rotor in electromotor for operating e.g. seat in motor car, has device part for adjusting signal offset depending on amplified signal and comprising voltage source
The arrangement (10) has a measurement circuit (12) for providing a signal (Uim) based on measurement of motor current (Im) and/or a motor voltage (Um) of an electromotor (M). An amplifier (14) i.e. operational amplifier, amplifies the signal with an adjustable signal offset to produce an amplified...

| description | The arrangement (10) has a measurement circuit (12) for providing a signal (Uim) based on measurement of motor current (Im) and/or a motor voltage (Um) of an electromotor (M). An amplifier (14) i.e. operational amplifier, amplifies the signal with an adjustable signal offset to produce an amplified signal (Us). An evaluating device (16) evaluates ripple of the amplified signal to determine current position of the rotor of the electromotor. A device part (16-3) adjusts the offset depending on the amplified signal and comprises a voltage source that is coupled with circuit nodes and resistors. An independent claim is also included for a method for determining current position i.e. rotational angle position, of a rotor in an electromotor.
Die Erfindung betrifft eine Schaltungsanordnung (10) zur Ermittlung der aktuellen Position, insbesondere Drehwinkelposition, eines Rotors eines Elektromotors (M), umfassend eine Messschaltung (12) zur Bereitstellung eines Signals (Uim) auf Basis einer Messung eines Motorstromes (Im) und/oder einer Motorspannung (Um) des Elektromotors (M), einen Verstärker (14) zur Verstärkung des Signals (Uim), um ein verstärktes Signal (Us) zu erzeugen, und eine Auswerteeinrichtung (16-1, 16-2) zur Auswertung einer Welligkeit des verstärkten Signals (Us), um die aktuelle Position des Rotors des Elektromotors (M) zu bestimmen. Erfindungsgemäß ist der Verstärker (14) dazu ausgebildet ist, das Signal (Uim) mit einem einstellbaren Signaloffset zu verstärken, und weist die Schaltungsanordnung (10) ferner Mittel (16-3) zur Einstellung des Signaloffsets in Abhängigkeit von dem verstärkten Signal (Us) auf. |
