ABSTRACT:
An electromagnetic linear drive is disclosed which includes a stator divided into motor elements and which constitutes a path of movement for a movable vehicle. Each motor element includes an energy supply unit adapted to be switched on and off individually and a power control unit with which a memory is associated. The memory is capable of storing a number of different running speed control signals corresponding to a number of predetermined running characteristics. The speed control signals control each power control unit so that it will supply power to its associated motor element, resulting in a locally controlled speed of the vehicle which runs over the motor element. The locally controlled speed corresponds to the running characteristics selected. This locally controlled speed lies in the range from running speed zero to a given locally specific maximum speed predetermined individually for each respective motor element.
