Claim Text:
1. A ring-shaped stator having a double-layer configuration comprising: a first stator segment unit and a second neighbouring stator segment unit connected to the first stator segment unit, each stator segment unit comprising: wherein stator teeth of one of the first segment unit and the second segment unit define first stator tooth segments; wherein the stator further comprises discrete second stator tooth segments arranged over at least a portion of the first stator tooth segments; wherein the stator further comprises a plurality of bolts extending through at least a portion of the first stator segment unit, the second stator segment unit, the first stator tooth segments, and the second stator tooth segments such that the bolts hold the first and second stator tooth segments together, and the first and second stator segment units together, and wherein each of the plurality of second stator winding sections extending freely from the first stator segment unit fully overlaps a respective first stator winding section of the second neighbouring stator segment unit.
