Abstract
An electromechanical strut and method of moving a closure member of a vehicle between an open position and a closed position is provided. The electromechanical strut includes a power drive unit including a motor, a leadscrew, a planetary gearset operably connecting the motor to the leadscrew, and an electromechanical brake assembly. The electromechanical strut further includes a telescoping unit including an extensible tube and a drive nut for converting rotary motion of the leadscrew into linear motion of the telescoping unit. The electromechanical brake assembly is selectively moveable between an engaged state, wherein the leadscrew is prevented from rotating to prevent relative axial movement between the power drive unit and the telescoping unit, and a disengaged state, wherein the leadscrew is permitted to rotate to allow relative axial movement between the power drive unit and the telescoping unit.
