no. 1 approach

[0034] exist Figure 1 to Figure 3 The outline of the structure of the single-phase magneto generator as the rotating electrical machine according to the first embodiment is shown in FIG.

[0035] The magnet generator 1 (in the following description, it may be simply referred to as a "generator") is attached, for example, near an engine of a two-wheeled vehicle (not shown), and is rotated by the rotational force of the engine to generate electricity. The electric power generated by the generator 1 is supplied to a vehicle-side electrical circuit (not shown).

[0036] The generator 1 includes a stator (fixed body) 10 and a rotor (rotating body) 60 . The stator 10 includes an iron core 20 , a bobbin 30 , and a winding portion 50 . The iron core 20 is formed by laminating thin metal plates such as iron or electromagnetic steel sheets, for example. The core 20 has a substantially annular core body 21 (see figure 2 , image 3 ).

[0037] In addition, in the following descrip...

[0073] Next, use Figure 7 A second embodiment of the present invention will be described. In addition, the same reference numerals are assigned to the same structures as those of the first embodiment, and descriptions thereof are omitted, and only the differences from the first embodiment will be described below.

[0074] In the first embodiment, an example in which the circumferential direction CR width of both the teeth 22 and the insulating portion 32 in the winding portion 80 gradually expands toward the stopper 44 side outside the radial direction RA is shown. In an embodiment, such as Figure 7 As shown, the width in the circumferential direction CR of the teeth 22 constituting the winding portion 80 is constant in the radial direction RA as in the past.

[0075] On the other hand, only the circumferential direction CR width of the insulating portion 32 sandwiching the teeth 22 gradually increases from the bobbin body 31 side to the side opposite to the bobbin body 31...

no. 3 approach

[0078] Next, use Figure 8 A third embodiment of the present invention will be described. In addition, the same reference numerals are assigned to the same structures as those of the first embodiment, and descriptions thereof are omitted, and only the differences from the first embodiment will be described below.

[0079] In the above-described first and second embodiments, the circumferential direction CR width of the winding portion 80 is shown as an example in which the width in the circumferential direction CR gradually increases toward the outer side of the stopper 44 in the radial direction RA. However, in the third embodiment, as Figure 8 As shown, the axial direction AX width of the winding portion 80 gradually increases toward the stopper 44 side outside the radial direction RA.

[0080] In this case, since the width (thickness) of the teeth 22 in the axial direction AX is constant, only the insulating portion 32 sandwiching the teeth 22 has the width AX in the axia...

Abstract

This rotating electrical machine 1 is provided with a rotor 60 which is supported rotatably, a stator 10 which has a core 20 and is disposed with a gap of a prescribed size between the stator 10 and the rotor 60, and a bobbin 30 which is mounted on the core 20, wherein: the core 20 is provided with a plurality of teeth 22 extending outward in a radial direction RA; the teeth 22, in conjunction with an insulating portion 32 of the bobbin 30, form a winding attachment portion 80; an aluminum wire 81 is wound around the winding attachment portion 80 to form a winding portion 50; and the width ofthe winding attachment portion 80 gradually increases in the direction in which the winding progresses, from a starting point S at which winding of the aluminum wire 81 starts, to an ending point E atwhich the winding of the aluminum wire 81 ends.

Description

technical field [0001] The present invention relates to a rotating electrical machine such as a magnet generator mounted on a vehicle such as a motorcycle. Background technique [0002] In general, a vehicle such as a two-wheeled vehicle is provided with a generator that generates electricity by the rotation of an engine mounted on the vehicle. The battery is charged by the power generated by the generator, and the electric power of the electric system of the vehicle is supplied by the charging power. [0003] As the generator, a so-called magnet generator, which is a rotating electrical machine, is often used. The magnet-type generator includes a magnet-equipped rotor (rotating body) arranged inside a crank cover of an engine, and a stator (fixed body) arranged radially inward of the rotor. The stator includes an iron core having a plurality of teeth, and a lead wire (copper wire) is wound around an insulating portion of a bobbin attached to a portion of the plurality of ...
