Abstract
Abstract An electromagnetically operated suspension vehicle which is coordinated to a guideway and which includes an asynchronous linear motor, in which the lift magnets and the linear motor together with their corresponding steel and aluminum reaction rails are arranged at the underside of the guide-way in such a manner that the vertical distance between the lift magnets and the linear motor, on the one hand, and the reaction rails, on the other, becomes larger when the lift magnets fail.
