Abstract: Disclosed herein is an inner rotor type permanent magnet excited transverse flux motor, in which a laminated structure in an axial direction or in a radial shape is applied to a stator iron core so as to employ a small amount of permanent magnets compared with a conventional outer rotor type permanent magnet excited transverse flux motor, thus providing high output power, increasing the efficiency of power generation, and reducing noise and vibration.

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.
