Stator core with a structure to improve assembly characteristics

A stator core with a reinforced coupling structure, the stator core comprising:

• a stator core body comprising a plurality of teeth protrusively formed at a predetermined interval;
• a fixing unit provided in a complementary shape at both ends of the stator core body;
• a plurality of hook units each having a complementary shape around a protrusion of the adjacent teeth to maintain a cylindrical shape in a bending process;
• and
• an insulator comprising a first insulator and a second insulator discretely formed, each of the first and second insulators being integrally formed in a mold to wrap the stator core body and the teeth simultaneously,
• wherein the fixing unit comprises a pin groove formed at both ends of the stator core body and a fixing pin adjustably inserted into the pin groove,
• wherein each of the first and the second insulators comprises a bottleneck formed at a position where each hook unit is disposed, and
• wherein the bottleneck is configured to be fractured to form a separate neck unit by bending the stator core body together with the insulator in the cylindrical shape.
