ABSTRACT:
A linear motor supporting apparatus for a linear motor elevator capable of greatly dampening a load from a stator when a relative displacement of the stator and guide rails occur, includes a linear motor including a rotor and a stator; a tensile force adjusting device, disposed below the stator, for adjusting a tensile force upon the stator; and a stator displacement adjusting device, disposed between the tensile force adjusting device and a supporting frame, for greatly reducing a load upon the stator by moving the stator by as much as a relative displacement between the stator and the rotor.
