<p>The linear drive device comprises two motors (M1, M2) which are interconnected. One of said motors drives the nut (10) and the other one drives the screw (20). The nut (10) is axially fixed with respect to its motor (M1), whereas the screw (20) is driven by the motor (M2) through a coupling member (21) which cannot turn but is axially movable.</p> |
