ABSTRACT:
A rotor provided in rotary electric machines comprises a stator core having a radial direction and slots provided with bottomed openings directed in the radial direction. The rotor also comprises a stator coil comprising slot accommodation portions being accommodated in the slots of the stator core and coil end portions each connecting mutually adjacent slot accommodation portions among the slot accommodation portions and respectively protruding from both end faces of the stator core. The stator coil is pre-formed into a cylindrical shape before the slot accommodation portions are accommodated into the slots of the stator core. The slot accommodation portions are formed to respectively have convex parts each protruding toward an opposite way to the slot openings, before the slot accommodation portions are accommodated into the slots. The convex parts are pressed by the stator core toward the openings during accommodation of the slot accommodation portions into the slots.
