PROCESS AND DEVICE FOR CONTROLLING A MOTOR-DRIVEN ACTUATOR
With motor-driven actuators for a control element (4) having a defined locking position, for example a fixed end stop, care must be taken to ensure that in the locked position the control element is clamped with a defined torque. According to the invention therefore, the maximum torque available on the motor (2) is increased after the control element starts to move into a locked position. In an advantageous embodiment of the process for an actuator with an electric motor, the reaching of the locked position is monitored by measuring the motor current and the torque is increased by controlling an actual voltage applied to the electric motor. A device for carrying out the process is also disclosed.
