Abstract
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.
