The present invention discloses a hinged stator core. The hinged stator core consists of a plurality of individual iron cores each comprising teeth on an inner side and a yoke on an outer side; two adjacent individual iron cores are connected by a hinge structure comprising a hinge and a hinge slot fitted with the hinge, with both the hinge and the hinge slot being arranged on the yoke of the individual iron core; the hinge and the hinge slot are arranged on a side, which rotates about a rotor shaft clockwise and/or on a side, which rotates about a rotor shaft counterclockwise, of the yoke of the individual iron core; the hinge consists of a fitting segment fitted with the hinge slot and a connecting segment for connecting the fitting segment with the yoke; the fitting segment has a circular or segmental shape along a radial cross-section of the rotor shaft; the hinge slot has an arced shape along the radial cross-section of the rotor shaft; and both a center of a circle of the fitting segment of the hinge and a center of a circle of the hinge slot are in the circumference of a circle taking a center of the stator core as its center. The present invention has the advantages of convenient manufacturing and processing, more convenient wire winding, and high integrity of the magnetic circuit.
