Abstract
A stator structure includes at least one stator part having a single rolled steel sheet to serve as a waist post with a gap. A first stator part includes a first engaging portion. A second stator part includes a second engaging portion corresponding to the first engaging portion. The first and second stator parts are of the same material. When the first stator part is assembled with the second stator part, the first engaging portion is engaged with the second engaging portion so as to form the stator structure with a waist post.
