Abstract: A winding module of permanent magnet electric machinery is described, in which coils of an electric machinery winding and a sensing device are integrally arranged. The winding module includes a base, a plurality of electric machinery windings formed on the base, and a plurality of sensing devices formed at intervals on the base. The coils of the electric machinery winding and the sensing device are integrally formed on the base by using a technique for forming a printed circuit board, thereby improving the process yield rate and quality controllability, effectively reducing the volume of the electric machinery, thinning the structure, saving time and cost required for installing a position sensor, simplifying the process for fabricating the electric machinery, and preventing the position sensor from being affected by environment and temperature, so as to have a highly robust effect.

Abstract: 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.

Abstract: A roller 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 up by a tubular-shaped magnet rotor unit having a plurality of magnet rotors fitted inside, with every two abutting magnets axially and biasly positioned. Then, a combination unit composed of a bearing and a bearing outer cover is fixed respectively at two ends of the magnet rotor unit. Thus, the roller unit is completed, having gaps of 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.
