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