PROBLEM TO BE SOLVED: To improve flexibility in controlling an ropeless elevator driven by a linear synchronous motor. SOLUTION: This ropeless elevator system includes a movable car, the secondary side of the liner motor provided in the car, and the primary side of the linear motor opposing to this secondary side. In this system, the secondary side is provided with a first leg La fixed to a secondary leg Lb, forming a passage, and this first leg La forms a clearance section. In addition, the secondary side has a permanent magnet arranged in the clearance section and a conductive coil W, which is coiled around a part of the second leg Lb and passes through the passage. |
