Why physic doesn't work in the sequencer?

Hi all, with the sequencer I’m rotating the two fans. If I don’t add the white object in the sequencer then the collisions work and it is transported by the fans, but when I put the white object in the sequencer to move it before to arrive at the fans, the collisions don’t work. I even try to apply the simulate physic like static mesh component to the object in the sequencer but doesn’t work. Could anyone help me?
