Problems solved by technology

In addition, since the U-shaped electric conductor is inserted after the insulating paper is inserted into the groove, the electric conductor may come into contact with the insulating paper when inserted, and may bite into the insulating paper, so that proper insulating performance cannot be ensured.

Embodiment Construction

[0063] Hereinafter, embodiments of the present invention will be described based on the drawings. It should be noted that the drawings are viewed along the direction of the symbols.

[0064] Such as figure 1 , figure 2 and Figure 5 As shown, the stator 10 of the rotating electrical machine according to this embodiment includes a stator core assembly 20 and a pair of base plate assemblies 30L, 30R. The base plate assemblies 30L, 30R are arranged and assembled on both sides of the stator core assembly 20 . An insulating sheet 65 such as a silicon wafer is arranged between the stator core assembly 20 and the base plate assemblies 30L, 30R to insulate the stator core assembly 20 from the base plate assemblies 30L, 30R.

[0065]The stator core assembly 20 includes a stator core 21 and a plurality (48 in the embodiment shown in the figure) of coil bars 25 .

[0066] The stator core 21 is formed by laminating, for example, a plurality of punched silicon steel sheets, and includ...

Abstract

The invention provides a stator for an electric rotary machine which can be built up without using exclusive equipment and which has superior mass-production properties and a fabrication method of the same. The stator (10) includes: a stator core (21); and segmented coils (50) of a plurality of phases, wherein: the segmented coils (50) of a plurality of phases have pluralities of coil bars (25) which are inserted individually in a plurality of slots (23) in the stator core (21) and which extend substantially in a straight line and pluralities of connection coils (40) which connect together the coil bars (25) of the same phase to thereby make up extending portions; and the coil bars (25) are fixed in place individually in the slots (23) in the stator core (21) in such a state that the coil bars (25) each are covered by an insulation material.

Description

technical field [0001] The present invention relates to a stator of a rotating electrical machine mounted in an electric vehicle, a hybrid vehicle, or the like. Background technique [0002] Conventionally, there is known a stator of a rotating electrical machine in which coils are formed by winding windings on teeth of a stator core. In addition, as the stator of other rotating electric machines, there is also known a stator configured as follows: After inserting a plurality of segments (segments) composed of electric conductors formed in a U-shape using segmented coils into the slots of the stator core, inserting the legs A part is bent, and the ends of the segments are joined together to form a coil (for example, refer to Patent Documents 1 and 2). [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2003-158840 [0004] [Patent Document 2] Specification of US Patent No. 6894417 [0005] However, in a conventional rotating electric machine in which a coil is prod...
