Embodiment Construction
[0022] Reference will now be made to Figures 1A through Figure 7 The electric compressor 10 according to one embodiment of the present invention will be described. In the description of this specification, the front side and the rear side correspond to the left side and the right side in FIG. 1A , respectively.
[0023] The electric compressor 10 shown in FIG. 1A is a scroll electric compressor. The rotary motor M of the electric compressor 10 includes a rotor 11 , a rotary shaft 12 , a stator 13 , a motor casing 14 , a compression operating body (in this embodiment, a movable scroll 15 ), and a fixed scroll 16 . The rotor 11 is fixed to the rotary shaft 12 , and the stator 13 is firmly fitted to the inner circumferential surface of the motor housing 14 . The active reel 15 moves around the axis of the rotary shaft 12 as the rotary shaft 12 rotates. When the movable reel moves around the track, the compression chamber 17 between the movable reel 15 and the fixed reel 16 mo...

An interphase insulating sheet of rotating electric machine and a manufacturing method thereof, as well as an electronic compressor, are disclosed. The interphase insulating sheet includes a first insulating portion, a second insulating portion, and at least one bridge piece. The first insulating portion includes at least one first coupling aid integrally provided with the first insulating portion to extend from an opposing end of the first insulating portion facing the second insulating portion. The second insulating portion includes at least one second coupling aid integrally provided with the second insulating portion to extend from an opposing end of the second insulating portion facing the first insulating portion. A first end portion of the bridge piece is heated welded to the first coupling aid. A second end portion of the bridge piece is heated welded to the second coupling aid. The first coupling aid has a first positioning hole. The second coupling aid has a second positioning hole. The first end portion of the bride piece includes a third positioning hole, which overlaps the first positioning hole. The second end portion of the bride piece includes a fourth positioning hole, which overlaps the second positioning hole.
Description
technical field [0001] The present invention relates to an interphase insulating sheet for a rotating electrical machine, a method of manufacturing the interphase insulating sheet, and an electric compressor. Background technique [0002] Japanese Laid-Open Utility Model Publication No. 59-37851 discloses an interphase insulating sheet for insulating each end of a coil of one phase from each end of a coil of another phase in a rotating electric machine. The interphase insulating sheet disclosed in the above publication includes a pair of coil end insulating parts disposed between the coil ends and insulating the coil ends from each other, and a connecting piece inserted in the stator slot. The pair of coil end insulators and the connectors are separately formed, and both ends of each connector are thermally welded to the pair of coil end insulators. Small holes of the same diameter are provided in each end of each connector and the pair of coil end insulations. A rivet for...
