Abstract
Transportation system comprising a large number of platforms which can be displaced along guides and a smaller number of displacement devices which can be coupled to and uncoupled from the said platforms. Each displacement device comprises a linear actuator comprising a moving part and a stationary part. The stationary part comprises a laminated plate assembly with coils, and the moving part comprises a structure with permanent magnets, such as neodymium magnets. On the linear actuator, there may be a further linear actuator, so that movement in two directions is possible. A transportation system of this type can be used in a parking garage for positioning vehicles.

Transportation system comprising a number of platforms which can be moved along guides as well as a smaller number of displacement devices which can be coupled to and uncoupled from the said platforms, said displacement devices being displaceable along further guides and being realised such that they can move under said displaceable platforms in order to act thereon, said displacement devices comprising a linear actuator comprising a moving part and a stationary part, both provided with means for generating a magnetic field, said means for generating a magnetic field for the moving part comprising coils which are accommodated in a laminated plate assembly, said moving part being provided with a bridge frame bridging said stationary part and provided with said means for generating a magnetic field and with wheels for positioning said moving part relative to said stationary part.
Linear actuator comprising a moving part to be moved along opposite rails and a stationary part, both provided with means for generating a magnetic field, said means for generating a magnetic field for the moving part comprising coils which are accommodated in a laminated plate assembly, said moving part being provided with a bridge frame bridging said stationary part and provided with said means for generating a magnetic field and at opposite sides with wheels engaging said rails for positioning said moving part relative to said stationary part.
