A second vertical side part 120b of the frame element 120 is arranged on a second vertical side face 111b of the cabin 111. These left-hand and right-hand vertical side faces 111a and 111b adjoin a front side 111c of the cabin 111, that is to say a face of the cabin with a cabin door 112.

[0058] Furthermore, a first rail 102a and a second rail 102b are arranged in the elevator shaft 101. These first and second rails 102a and 102b are embodied as guide rails for the elevator car 110.

[0060] In the example in FIG. 1, the elevator system 100 comprises two such linear motors 400. A primary part 410 of a first linear motor 400 is arranged on the first rail 102a. A secondary part 300 of the first linear motor 400 is arranged on the first side part 120a of the frame element 120. A primary part 410 of the second linear motor 400 is arranged on the second rail 102b. A secondary part 300 of the second linear motor 400 is arranged on the second side part 120a of the frame element 120.

[0061] FIG. 2 is a schematic illustration of a perspective view of the chassis element 120 embodied as a frame element, according to FIG. 1.

[0062] FIG. 3 is a schematic illustration of a perspective view of the secondary part 300 of a preferred refinement of a drive 400 according to the invention according to FIG. 1.

[0063] The secondary part 300 comprises a U-shaped supporting element 310. The U-shaped supporting element 310 comprises two limbs 311 and 312 which are arranged parallel to one another, and a supporting structure 313 is which is arranged perpendicularly with respect to these limbs. The secondary part 310 can be attached to the chassis element 120 of the elevator car 110 by means of this supporting structure 313.

[0064] This U-shaped supporting element 310 is constructed, in particular from a carbon-fiber-reinforced plastic (CFRP). Such a U-shaped supporting element 310 can be fabricated as a U-profile, in particular by means of the fabrication method of extrusion.

[0065] In each case a layer 320 made of a ferromagnetic material, for example steel, is applied to the inner sides of the two limbs 311 and 312 which are arranged parallel to one another.

[0066] On this layer 320, a magnet element 330 is arranged on each of the limbs 311 and 312. The magnet elements 330 are also arranged parallel to one another. Each magnet element 330 comprises in each case a plurality of magnets 331, for example permanent magnets (only shown in detail for limb 311) which are arranged one on top of the other in the longitudinal direction of the supporting element 310.

[0067] FIG. 4 illustrates the elevator system 100 according to FIG. 1 in a schematic, plan view.

[0068] As is also apparent in FIG. 4, the primary part 410 of one of the linear motors 400 is arranged in each case on the first rail 102a and on the second rail 102b. The primary parts 410 are each embodied as copper coils.

[0069] The magnet elements 330 of the respective secondary parts 300 of the linear motors are arranged laterally next to these primary parts 410. The secondary part 300 of the linear motor 400 therefore encloses the respective primary part 410 of the respective linear motor 400.

[0070] A further preferred refinement of an elevator system according to the invention is illustrated schematically in FIG. 5, in a way which is analogous to FIG. 1, and denoted by 200. An elevator car 210 can be moved in an elevator shaft 201. The elevator car 210 comprises a cabin 211 and a chassis element 220.

[0071] FIG. 5 is a schematic illustration of the elevator system 200 with a second preferred refinement 220 of such a chassis element. The chassis element 220 is embodied as a backpack-type element.

[0072] The backpack-type element 220 is arranged on a rear side 211d of the cabin 211. The rear side 211d of the cabin is a vertically extending face of the cabin 211 which lies opposite a front side 211c of the cabin, this is to say a face of the cabin 211 with a cabin door 212.

[0073] Furthermore, a rail 202 is arranged in the elevator shaft 201. This rail 202 is embodied as guide rails for the elevator car 210. The backpack-type element 220 is arranged in the direct vicinity of the rail 202.

[0074] A preferred refinement of a linear motor according to the invention is provided for moving the elevator car 210 in the elevator shaft 201, in a way analogous to FIG. 1 or FIG. 3.
