Method for positioning a part and device for carrying out the method

Abstract

A method for positioning a part and a device for carrying out the method is proposed. The positioning device contains an electric motor (10) which is connected via a coupling (11) to the part (12) to be positioned and to an actual position value transmitter (13). The motor (10) can be connected to an energy source via a motor driver circuit (20) in dependence on the driver control signals (23, 24) generated by a control circuit (51). The control circuit (31) exhibits at least one control input (33, 34), to which a switch-off signal for the driver (20) or the motor (10), respectively, can be applied. The switch-off signal is generated by at least one comparator (43, 44) in dependence on the actual position value emitted by the actual position value transmitter (13). Two thresholds (46, 47) are preferably predetermined which correspond to the mechanical stops (14, 15) of the part (12) to be positioned. A time delay (48, 49) between when the stop (14, 15) is reached and the switch-off signal ensures that the part to be positioned is pressed against the stop (14, 15) with a certain pressure force.

Dependencies are inferred from the claim text.
