ABSTRACT:
An electromagnetic linear drive including at least two stators divided into motor elements which constitute two paths of movement for movable vehicles in opposite directions is disclosed. An energy supply unit, including a power control unit, is associated with each of two opposed motor elements belonging to one or the other path of movement. The energy supply unit is selectively connectable to the motor element of one path of movement or to the motor element of the other path of movement, as required. When a vehicle is located above both motor elements associated with a single energy supply unit, the common energy supply unit is connected, according to a predetermined selection, to one of the two motor elements or alternated between both motor elements.
