Abstract
A stator core includes at least one bendable strip-shaped core. Each strip-shaped core is formed by stacking a plurality of laminations. Each lamination includes at least two yoke portions and at least two tooth portions. Every two adjacent yoke portions are connected to each other via a bendable portion and have two opposite end surfaces, one of the end surfaces having a groove and the other having a projecting rib. After the bendable portion is bent the projecting rib is engaged in the groove to form an interlock structure such that relative circumferential movement between the adjacent yoke portions is limited.
