Embodiment Construction
[0025] figure 1 is a schematic sectional view of the refrigerant compressor 1 . The refrigerant compressor 1 includes a compressor assembly 2 and an electric motor 3 , the electric motor 3 is an external rotor type electric motor, and the electric motor has an external rotor 4 and an internal stator 5 . The rotor 4 comprises permanent magnets 6 surrounded radially by short rings 7 . The rotor 4 is connected non-rotatably to a shaft 9 via a plate-shaped base 8 . The lower end of the shaft 9 is immersed in an oil pool not shown.
[0026] An annular air gap is formed between the rotor 4 and the stator 5 . The stator 5 comprises a stator lamination 10 and a winding 11 . Furthermore, the stator 5 includes an upper cover plate 12 and a lower cover plate 13 . The cover plates 12 , 13 include radially inwardly directed projections 14 which engage with correspondingly formed parts 15 of the protruding housing 16 of the stator lamination 10 .
[0027] The shaft 9 is supported radi...
