A stator iron core of an electric motor including plural magnetic pole segments. Each of the pole segments include a back yoke portion, a teeth portion projected from the back yoke portion, a connection portion provided to the back yoke portion for connecting adjacent magnetic pole segments, and a stepped-shaped notch on an outer circumference of the back yoke portion. Further, the stator iron core is circularly formed by bending the connection portions of the plural magnetic pole segments.

Stator iron core of electric motor, manufacturing method thereof, electric motor, and compressor

A stator iron core of an electric motor including plural magnetic pole segments connected and confronted by plural confronting surfaces. Further, two of the confronting surfaces respectively include a V-shaped projection and a V-shaped recess.

In a scroll compressor, a clearance is made between the opposed faces of a bed plate of a fixed scroll and a stationary member and a compression gas is introduced into the clearance for pressing the fixed scroll against an orbiting scroll. A recess is made in the center of the stationary member, is surrounded by a muffler, and is formed with a discharge hole directed in a radial direction. The scroll compressor can be assembled efficiently.
