Linear drive for an elevator system

A linear drive for an elevator system, the elevator system including an elevator shaft and an elevator car movable in a displacement axis direction in the elevator shaft, the linear drive comprising:

• a magnetic track having at least one row of permanent magnets mounted in a carrier, each of the permanent magnets having an axis of rotation and being rotatable about the axis of rotation;
• a force-transfer member formed of an electrically conductive material;
• wherein one of the magnetic track and the force-transfer member is fixed to the elevator shaft and another of the magnetic track and the force-transfer member is fixed to the elevator car;
• wherein the permanent magnets in the at least one row are arranged one adjacent another in the displacement axis direction;
• wherein the magnetic track and the force-transfer member are displaceable relative to each other in the displacement axis direction;
• wherein the magnetic track and the force-transfer member lie opposite one another in an overlap region, and ones of the permanent magnets located in the overlap region are separated by an air gap from a portion of the force-transfer member lying opposite;
• and
• a rotary drive rotating the permanent magnets such that a traveling field moving in the displacement axis direction is generated by superposition of magnetic fields of the rotating permanent magnets, the traveling field displacing the force-transfer member relative to the magnetic track in the displacement axis direction.
