Abstract
An actuator () comprises an electric motor () for moving an actuated part () to an actuated position. The actuator () further comprises a controller () connected to the electric motor () and configured to determine a motor current of the electric motor () and to detect motor rotations. The controller () is further configured to determine the actuated position by counting the motor rotations detected while the motor current is at or above a current threshold indicative of a load torque, and by not counting motor rotations detected while the motor current is below said current threshold.
