Contactless driving module and transfer apparatus having the same

A contactless driving module comprising:

• a pair of running rails extending parallel with each other and comprising a first running rail comprising a plurality of first permanent magnets arranged in an extending direction and a second running rail comprising a plurality of second permanent magnets arranged in the extending direction;
• a driving wheel disposed between the running rails to be spaced apart from the running rails and comprising a plurality of third permanent magnets arranged in a circumferential direction;
• and
• a driving unit for rotating the driving wheel, wherein
• at least one of the third permanent magnets is disposed between the first permanent magnets and the second permanent magnets, and
• propulsive force in the extending direction is generated by magnetic force between the first permanent magnets and the third permanent magnets and between the second permanent magnets and the third permanent in magnets.
