<p>Method and apparatus for controlling an assembly (1) of an electrical motor (2) and a rotation-translation converter (3) connected to said electrical motor, comprising the steps of energising said electrical motor (2) with a predetermined current (I) for obtaining a torque overcoming the internal friction of said rotation-translation converter (3) and increasing said current (I) until said electrical motor (2) provides a total torque, which is converted by said rotation-translation converter (3) into a predetermined force (F1) on or a displacement of an object (4) moveable by said rotation-translation converter, characterised in that the method comprises the further step of reducing the current (I) through said electrical motor (2) after reaching said predetermined force (F1) to a predetermined current value, during which said predetermined force (F1) on said object (4) remains substantially equal.</p> |
