Abstract

PURPOSE:To eliminate the lengthiness of each linear motor coil by vertically providing a guide rail with the transverse section in H shape to serve as the secondary conductor of a linear motor and respectively arranging the linear motor coils provided in a balance weight, in opposed surfaces. CONSTITUTION:A cage 6 and a balance weight 8, arranged in a lift path 1, are mutually suspended through pulleys 3 by a main rope 9, the cage 6 can be lifted along a rail 5, and the balance weight 8 can be lifted along a guide rail 12 with the transverse section in H shape. Here the guide ail 12, vertically provided in a self-standing condition, serves for the secondary conductor of a linear motor. While linear motor coil 13s opposed to a flange surface with the section in H shape of the guide rail 12, are arranged in the balance weight 8, and a cable 14, drawn out from a lift path wall 1a, is connected to the coils 13. When power is fed to the linear motor coils 13 from the cable 14, linear motor action is generated with the guide rail 12 to lift the cage 6. Thus, lengthiness of each linear motor coil can be eliminated.

The linear motor coils provided on the counterweights are arranged on the symmetrical surfaces of the guide rails, and the elevator is operated by the counterweights, which are guided by the guide rails and moved up and down by supplying power to the linear motor coils through moving cables. It's something you drive. This eliminates the need to increase the length of the linear motor coil to correspond to the length of the elevator's ascending and descending strokes, suppresses the increase in production costs even if the tI3 model becomes high-rise, and allows the counterweight to be used as a single guide. Since it is guided by rails, it is possible to reduce production and installation costs.
