Patent ID: 7166938

Claim:
A horizontal and vertical transportation system capable of linearly transporting an object in the horizontal direction and in the vertical direction, comprising: a horizontal transportation unit for transporting the object in the horizontal direction by means of a thrust from a permanent magnet excited transverse flux horizontal linear motor; and a vertical transportation unit installed on the horizontal transportation unit for transporting the object in the vertical direction by means of thrusts from permanent magnet excited transverse flux vertical linear motors, wherein the horizontal transportation unit comprises: a permanent magnet excited transverse flux horizontal linear motor having a stator part and a movable element part; a supporting member, the stator part of the transverse flux horizontal linear motor being fixed to the supporting member; a horizontal mover fixing element, the movable element part of the transverse flux horizontal linear motor being fixed to the horizontal mover fixing element, the horizontal mover fixing element being horizontally movable together with the movable element part of the transverse flux horizontal linear motor; and a linear bearing disposed at both sides of the supporting member and at both sides of the horizontal mover fixing element so that the linear bearing part disposed at the two sides of the supporting member is opposite to the linear bearing part disposed at the two sides of the horizontal mover fixing element, the linear bearing horizontally moving the horizontal mover fixing element and the movable element part of the transverse flux horizontal linear motor in a sliding fashion.
