- An appropriate amount of the resin 5 can be arranged, and it is possible to form a uniform evenly in a multi-row, multi-layer reel.
- the resin is applied to the conductor every time the coil is wound, so that the resin can be freely increased or decreased at a desired winding point, and at least the deep layer can be uniformly and evenly applied, and various patterns can be formed at low cost. Can be manufactured.
- heating is performed at the stage of winding around the winding frame.
- the conversion may be performed after the core is assembled.
- the resin 7 is evenly interposed between the conductors to counter centrifugal force.Therefore, the necessity of wrapping a protective tape around the outermost layer of the conductor as the final step is not necessary except in special cases. Disappears.
- the resin 7 is uniformly formed in the gaps between the conductor wires 6 wound around the winding frame 5, so that the conductor Line 6 can be kept in place.
- the conductor wires 6 are rubbed against each other and are disconnected.
- the heat conduction is dramatically improved, and the resin (having a heat conductivity about 10 times that of air) is obtained. ), The main heat conduction is performed, so that the conductor temperature in the winding frame can be reduced and the output of the generator per number of windings can be improved.
- heat conduction is promoted in the winding area deeply surrounded by the windings, that is, in the deep part 22 of the field winding, so that there is no exit inside the winding. Heat can be discharged.
- the thermal difference between the non-deep part cooled by the moving air due to the rotation (the winding area where the winding frame or the external world is present in the vicinity after the winding is completed) 23 and the above-described deep part Differences are reduced, cooling leveling is improved, and cooling efficiency of the whole winding is improved.
- the winding wound is a continuous continuum, and the overall cooling efficiency tends to decrease due to the presence of a certain high-temperature part. From this point, the above cooling leveling leads to a significant improvement in cooling efficiency. It is.
- the range in which the uniformly provided resin occupies the gap between the aligned conductors is within the range that is smaller than the gap between the aligned conductors, that is, between the conductors excluding the resin. It is preferable that the resin 7 is provided densely, whereby the amount of the resin 7 to be charged is adjusted to the minimum necessary amount, so that the production cost, the heat efficiency, and the space efficiency are not deteriorated.
- the conductor wire 6 is a round wire having a diameter of 0.8, but if the wire has a diameter of 0.5 mm or more, substantially the same effect can be obtained. This is derived from the fact that the cross-sectional area of the resin provided in the space between the conductors is required to some extent. Further, when the number of layers is 10 or more, heat is difficult to dissipate, and the impregnated resin forms a deep portion 22 that does not spread over the entire surface. However, according to the present invention, such a deep portion 22 is formed. Therefore, the reliability and temperature of the winding conductor can be reliably improved.

- the gap between the outer peripheral surface of the hollow body 51 and the innermost layer (first layer) of the conductor wire 6 can be reduced beforehand (usually, the second layer).
- the gap will be larger than the gap between the subsequent conductors), and the amount of applied resin can be reduced to an appropriate amount. Also, since no extra resin is interposed in the immediate vicinity of the iron core, the heat is good and the cost is reduced.
- Embodiment 3 In each of the above-described embodiments, the force indicated when the conductor 6 is a round wire is based on the reason that it is easily available and has versatility. However, as shown in Fig.
- any gap between the conductors will not The situation that arises remains the same and can be used to achieve the intended purpose.
- a conductor wire having a rectangular cross section or the like when the surfaces are arranged and wound so that they face each other, the space between the surfaces is relatively small, but it is practically and electrically insulated. Since a round shape is always formed at the wire surface angle, this portion has the same structure as the round wires, and even in the case of the conductor having a polygonal cross section, the diameter of the round wire is 0.5. It is equally effective if the size is equal to or greater than a marauder.
- the rotor of the rotating electric machine according to the present invention is not only a rotor of an AC generator for a vehicle, but also a rotor of any other rotating electric machine that winds conductors in multiple rows and multiple layers. It is widely used.
