MOTEUR ÉLECTRIQUE LINÉAIRE, ASCENSEUR ET PROCÉDÉ DE COMMANDE DE ROTATION D'UN ENTRAÎNEMENT PAR RAPPORT À UN FAISCEAU DE STATOR D'UN MOTEUR ÉLECTRIQUE LINÉAIRE

摘要

An electric linear motor (5), an elevator (100) and a method for controlling rotation of a mover (20) with respect to a stator beam (16) are presented. The electric linear motor (5) comprises a number of stator beams (16), wherein at least one of them comprises stators (17) extending in a longitudinal direction (18) of the beam (16). The motor (5) also comprises a number of movers (20), wherein at least one them comprises armatures (22), wherein each armature (22) is adapted for establishing an electromagnetic coupling with a corresponding stator (17) for moving the mover (20). The motor (5) also comprises air gap regulation means for regulating movement of the mover (20) with respect to the stator beam (16), wherein the means comprise guide element(s) (71-73, 81) arranged for limiting the rotation of the mover (20) with respect to the stator beam (16).
