Abstract

The invention refers to an electric linear motor, control apparatus, transport system and a method. The electric linear motor comprises a longitudinal stator beam (1); at least one mover (24, 26) at least partially surrounding the stator beam (1) and adapted to move along the stator beam (24, 26); which stator beam comprises at least two side faces (6A, 6B; 6C, 6D) located at opposite sides of the stator beam (1), each of the side faces (6A, 6B; 6C, 6D) carrying ferromagnetic poles (8) spaced apart by a pitch (8'), and which mover comprises at least two counter-faces (7A, 7B; 7C, 7D) facing the respective side faces (6A, 6B; 6C, 6D) of the stator beam (1). The mover has in at least one of said counter-faces (7A, 7B; 7C, 7D) rotor units (2, 3, 4, 5) having at least one winding (74, 76) and at least one permanent magnet (71) arranged to co-act with the ferromagnetic poles (8) of the respective side faces (6A, 6B; 6C, 6D) of the stator beam (1). The ferromagnetic stator poles (8) of the stator beam (1) and the rotor units of the mover (24, 26) are used for generating propulsion forces for driving the mover (24, 26) along the stator beam (1) as well as for generating attraction forces to levitate the mover (24, 26) around the stator beam (1) while driving.
