The device includes at least a roller unit having a fixed immovable shaft rod combined with two coiled stator units having silicon steel stators respectively wound with a coil. Each coil stator unit has its outer circumference covered by a tubular-shaped magnet rotor unit having magnet rotors fitted inside, with every two abutting magnets axially and biasly positioned. A combination unit composed of a bearing and a bearing outer cover is fixed respectively at two ends of the magnet rotor unit. The roller unit includes gaps between the magnet rotors and gaps between the magnet rotors and the silicon steel stator. When the coiled stator units are electrically connected, the magnet rotor unit will rotate around the coiled stator unit.
