Title:
ELECTRIC SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2015/060037
Kind Code:
A1
Abstract:
To reduce deformation of an endplate in an electric scroll compressor that supports the thrust load of an orbiting scroll by means of the endplate and that is provided with a housing member in which a motor securing part and the endplate are integrated. [Solution] An electric scroll compressor wherein stator contacting parts (61) that contact a stator (41) of an electric motor (4) and stator non-contacting parts (62) that do not contact the stator are alternately arranged in the circumferential direction on the inner peripheral wall of a motor securing part (6a). Holes (63) are provided at positions on an endplate (6b) that correspond to the axial directions of the stator contacting parts (61), and inconvenient deformation of the endplate (6b) as a result of diameter expansion deformation of the motor securing part (6a) is prevented. Furthermore, reinforcing ribs (65) that reinforce the endplate (6b) are provided at positions on the endplate (6b) that correspond to the axial directions of the stator non-contacting parts (62), and deformation of the stator contacting parts (61) does not affect the endplate (6b) via the reinforcing ribs (65).
