Abstract: Disclosed herein is a horizontal and vertical transportation system using permanent magnet excited transverse flux linear motors which is capable of linearly transporting an object in the horizontal direction and in the vertical direction using permanent magnet excited transverse flux linear motors, thereby obtaining a simple structure of the system and preventing any occurrence of dust generated by abrasion between the parts of the system. The system comprises a horizontal transportation unit and a vertical transportation unit. The horizontal transportation unit is adapted for transporting the object in the horizontal direction by means of a thrust from a permanent magnet excited transverse flux horizontal linear motor. The vertical transportation unit is installed on the horizontal transportation unit. The vertical transportation unit is adapted for transporting the object in the vertical direction by means of thrusts from permanent magnet excited transverse flux vertical linear motors.

Abstract: Disclosed is an integrated system of a non-contact power feed device and a permanent magnet-excited transverse flux linear motor, in which a conventional structure of the permanent magnet-excited transverse flux linear motor system is still used and a driving force and non-contact type power are supplied to a shifter of the permanent magnet-excited transverse flux linear motor, thereby eliminating defects of the electrical power supply system occurring due to the contact friction.
