Container transporting apparatus and logistics processing system including the same

A container transporting apparatus for transporting a container containing a plurality of substrates in a semiconductor manufacturing plant, the apparatus comprising:

• a driving motor for generating a driving force;
• a driving wheel for generating a rotational force and moving the container transporting apparatus under the rotational force;
• a driving shaft for transmitting the driving force to the driving wheel;
• and
• an electronic gear coupled to the driving shaft and the driving wheel, wherein the electronic gear is embodied as a non-contact gear using a magnet.

A logistics processing system installed in a semiconductor manufacturing plant, the logistics processing system comprising:

• a container transporting apparatus for transporting a container containing a plurality of substrates;
• a container storage apparatus for storing the container therein;
• and
• a control device configured to control each of the container transporting apparatus and the container storage apparatus,
• wherein the container transporting apparatus includes:
• a driving motor for generating a driving force;
• a driving wheel for generating a rotational force and moving the container transporting apparatus under the rotational force;
• a driving shaft for transmitting the driving force to the driving wheel;
• and
• an electronic gear coupled to the driving shaft and the driving wheel, wherein the electronic gear is embodied as a non-contact gear using a magnet,
• wherein the electronic gear includes:
• a first core portion surrounding the driving shaft;
• a first magnet portion surrounding the driving shaft and adjacent to the first core portion;
• a second core portion surrounding the driving shaft and adjacent to the first magnet portion, wherein the second core portion includes a plurality of rods;
• a second magnet portion surrounding the driving shaft and adjacent to the second core portion;
• and
• a third core portion surrounding the driving shaft and adjacent to the second magnet portion,
• wherein each of the plurality of rods extends in a direction different from a longitudinal direction of the driving shaft,
• wherein a number of the plurality of rods is determined based on a number of pole pairs of the magnets included in the first magnet portion and a number of pole pairs of the magnets included in the second magnet portion,
• wherein a rotation speed of the second magnet portion is determined based on a rotation speed of the first magnet portion, a number of pole pairs of the magnets included in the first magnet portion, and a number of pole pairs of the magnets included in the second magnet portion.
