摘要： A rotary electric machine includes a rotor for rotation around a rotational axis, a stator core that has a cylindrical shape and includes a slot therein, a cooling unit having a coolant passage, and a casing that accommodates the rotor and the stator core. A stator coil is inserted in the slot of the stator core and has a coil end protruded from a side face of the stator core. An electric part is mounted on the cooling unit and controls a current of the stator core. The rotor is rotatably supported inside of the stator core. The cooling unit cools both the stator core and the electric part. The cooling portion is accommodated in spacing defined by the side face of the stator core and an outer circumference wall of the coil end.

摘要： A stator core is formed by arranging divided cores (20) in a circumference direction in cylindrical shape. On an upper end surface (60) of a core back (50) of the divided core, holes (62, 64) are made. Then, on the upper end surface, a reinforcing ring (40) having through holes (66, 68) is arranged, and is connected with rivets (70, 72). Thus, stress is transmitted not only through a side surface (58) but also through the reinforcing ring (40), between the adjacent divided cores. Thus, strength of the stator using a powder magnetic core is ensured and a space is saved.
