Abstract: The scroll compressor (2) comprises a hermetic enclosure (3) comprising a midshell (4), an upper cap (5) and a baseplate (6), the baseplate (6) comprising a mounting base (32) having a plate shape and including a central opening (33), and a central cap (28) arranged within the central opening (33), the central cap (28) comprising a concave portion (29) and a first cylindrical rim portion (30) extending upwardly and having an outer diameter substantially corresponding to an inner diameter of the midshell (4); a compression unit (11) configured to compress refrigerant; and an electric motor (21) configured to drive the compression unit (11) via a drive shaft (19). The mounting base (32) comprises a second cylindrical rim portion (34) extending upwardly and surrounding the central opening (33), wherein an inner diameter of the second cylindrical rim portion (34) substantially corresponds to the inner diameter of the midshell (4) and to an outer diameter of the first cylindrical rim portion (30).
