Abstract:
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 the stator beams includes a plurality of stators extending in a longitudinal direction of the stator beam, a number of movers, wherein at least one of the movers includes a plurality of armatures, wherein each one of the armatures is adapted for establishing an electromagnetic coupling with a corresponding one of the stators for moving the mover along said stator, and wherein at least one of the armatures is arranged to be offset from the aligned position with respect to the corresponding one of the stators in a perpendicular direction relative to the longitudinal direction.
