The functions of the fixed pulleys of the two housings are the same as above, avoiding the lateral pressure of the linear bearing 4 and increasing the running resistance of the stator and the mover.

In order to reduce dynamic friction, a sliding member can be arranged in the sealed cavity. The sliding member in this embodiment includes a linear guide rail 3 and a linear bearing 4.
