Beschreibung
Zusammenfassung:	An electric linear motor, an elevator and a method for controlling rotation of a mover with respect to a stator beam are presented. The electric linear motor includes a number of stator beams, wherein at least one of them includes stators extending in a longitudinal direction of the beam. The motor also includes a number of movers, wherein at least one them includes armatures, wherein each armature is adapted for establishing an electromagnetic coupling with a corresponding stator for moving the mover. The motor also includes an air gap regulator for regulating movement of the mover with respect to the stator beam, wherein the air gap regulator includes guide element(s) arranged for limiting the rotation of the mover with respect to the stator beam.
