发明名称 Electro-magnetic linear drive
摘要 An electromagnetic linear drive including a stator which constitutes a path of movement for a vehicle. The linear drive is equipped with current conductors, and is divided into a plurality of stator elements of equal length. A movable portion which constitutes a vehicle is preferably equipped with permanent magnets cooperating with the stator to provide the drive. The stator is divided into a number of motor elements, each motor element including a minimum number of stator elements as well as an energy supply unit adapted to be switched on and off individually by sensors disposed along the path of movement. All motor elements are designed for the same maximum performance, and motor elements of different lengths are provided. The length of each motor element is determined by the local need for maximum performance per unit length which exists at the location of the respective motor element in accordance with a predetermined speed characteristic at that point along the path of movement.
