A wound stator core disclosed is substantially formed from a spirally piled strip. In an embodiment, the strip with a specific length is formed with a first dentition and a second dentition, whereas the first dentition is featured by a first slot-number ratio and is composed of a first side and a plurality of first teeth in a manner that the plural first teeth are arranged as an array on the first side; which is also same to the second dentition while allowing the second slot-number ratio to be equal to the first slot-number ratio. In addition, each first tooth is formed with a first dental part at a free end thereof, while also each second tooth is formed with a second dental part at a free end thereof, and the first dental part of each first tooth is connected to the second dental part of its corresponding second tooth.

A die structure, a manufacturing method and a substrate, wherein the die structure is constituted by a chip on wafer (COW) and the substrate, and the substrate is formed by stacking and then cutting a plurality of thermal and electrical conductive poles and a plurality of insulating material layers. Moreover, the fabricating of the die structure comprises a plurality of COWs carried on a carrier board is bonded on the substrate, the plurality of COWs are in contact with the plurality of thermal and electrical conductive poles on the substrate, and then the carrier board is removed. After that, a phosphor plate is adhered on the plurality of COWs so as to form a stacked structure. Thereafter, the stacked structure is cut, thus forming a plurality of die structures having at least one COW.

A rotational kinetic energy output device includes a housing component, a rotational component and a magnetism generating component. The rotational component includes a rotational body pivotally connected to the housing component, and the rotational body has at least one magnetic element. The magnetism generating component includes a plurality of magnetizers and coils wound on the magnetizers, the magnetizers are disposed in the housing component and surround the rotational body. Each of the magnetizers has a first magnetic arm and a second magnetic arm extended respectively toward the rotational body, and the rotational body is disposed between the first magnetic arm and the second magnetic arm. Thereby, the rotational kinetic energy output device allows a force to be balancedly exerted on the rotational body and a thin shape is also achieved.
