Abstract
A stator member of a linear motor type elevator system is mounted in the elevator hoistway so as to permit vibrational movement of the stator to occur. The stator mounts permit rotational movement of the stator and also apply a longitudinal tensioning force to the stator. The tensioning force is supplied by a spring which absorbs vibrations of the stator.
