Refrigerant compressor for domestic refrigerator or freezer in house, has housing upwardly tapering towards side of motor that is turned away from impeller, where stator includes different cross-sections in two axial sections

摘要

The compressor (1) has a hermetically closed housing (2), an impeller (4), and an electric motor (3) that includes a stator (10) and rotor (9). The rotor is rotatable around an axis. The housing upwardly tapers towards a side of the motor that is turned away from the impeller, where the stator includes different cross-sections in two axial sections (14, 15). The cross-sections include different lengths, where one of the axial sections with maximum cross-section is arranged in an axial region of the stator that is adjacent to the impeller.
