Research output: Patent


The invention refers to an electric linear motor, control apparatus, transport system and a method. The electric linear motor comprises a longitudinal stator beam; at least one mover at least partially surrounding the stator beam and adapted to move along the stator beam; which stator beam comprises at least two side faces located at opposite sides of the stator beam, each of the side faces carrying ferromagnetic poles spaced apart by a pitch, and which mover comprises at least two counter-faces facing the respective side faces of the stator beam. The mover has in at least one of said counter-faces rotor units having at least one winding and at least one permanent magnet arranged to co-act with the ferromagnetic poles of the respective side faces of the stator beam. The ferromagnetic stator poles of the stator beam and the rotor units of the mover are used for generating propulsion forces for driving the mover along the stator beam as well as for generating attraction forces to levitate the mover around the stator beam while driving.
