Abstract
Official abstract text for this publication.
An object is to provide a hermetic electric compressor that can simplify the installation structure of an internal protector and improve the ease-of-assembly thereof. In a hermetic electric compressor having a compressor and an electric motor ( 10 ) built into a sealed housing ( 2 ), the electric motor ( 10 ) includes a stator ( 8 ) to which plastic insulating bobbins ( 30 ) having flanges ( 30 B, 30 C) on an inner and outer circumferences of a plurality of tooth parts of a stator core are fitted and around which a stator winding wire ( 8 A) is wound in concentrated winding around the plastic insulating bobbins ( 30 ), and an internal protector ( 29 ) for electric-motor protection is latched between the inner and outer circumferential flanges ( 30 B, 30 C) of the plastic insulating bobbins ( 30 ) by being urged against the stator winding wire ( 8 A).
First claim
Opening claim text (preview).
The invention claimed is: 1. A hermetic electric compressor comprising: a compressor configured to be housed in a sealed housing; and an electric motor configured to drive the compressor and to be housed in the sealed housing, wherein the electric motor includes a stator to which plastic insulating bobbins having flanges on an inner and outer circumferences of a plurality of tooth parts of a stator core are fitted and around which a stator winding wire is wound in concentrated winding around the plastic insulating bobbins, and wherein an internal protector for electric-motor protection is urged directly against the stator winding wire and is latched between the inner and outer circumferential flanges of the plastic insulating bobbins. 2. The hermetic electric compressor according to claim 1 , wherein, on the inner and outer circumferential flanges of the plastic insulating bobbins, hooks for latching the internal protector are disposed, and the internal protector is fitted between the hooks and latched thereto. 3. The hermetic electric compressor according to claim 1 , wherein, on the inner and outer circumferential flanges of the plastic insulating bobbins, latching holes are provided, and the internal protector is latched between the inner and outer circumferential flanges with retainer plates latched to the latching holes.
