Definitions
- the stator assembly 1 is rotated around the axis while the varnish 4 is gelling, that is, for several minutes during the temperature rise process in the drying furnace. The rotation around the axis of solid 1 has stopped.
- the stator assembly 3D is rotated for a few minutes in the initial stage of the varnish heat curing step.
- the rotation time of the stator assembly 1 is not particularly limited. It is only necessary that the gel be formed and the fluidity be almost lost. Further, the stator assembly 1 may be rotated during the varnish heat curing step.
- each slot 11a six slot storage portions 13a are arranged in one row in the slot depth direction.
- the slots 1, 3, and 5 in one slot 11 a of the slot pair and the slot 11 a in the other slot 11 a The slot storage sections 13a at addresses 2, 4, and 6 and the power are connected by turn sections 13b, respectively.
- the turns 13 b are arranged in three rows in a circumferential direction at a pitch of one slot to form a coil end 12 r.
- the stator assembly 10 is preheated to 150 ° C. in a drying furnace. Then, the stator assembly 10 heated to 150 ° C is taken out of the drying furnace, and the varnish 4 adjusted so that the viscosity at 100 ° C is 22 mPas is fixed. While rotating the child assembly 10 around the axis at 36 r / min, apply and drip the coil ends 12 f and 12 r from outside in the radial direction. Next, the stator assembly 10 to which the varnish 4 has been applied is placed in a drying oven and heated to 160 ° C. At this time, the stator assembly 1 is rotated around the axis at 36 r Zmin for the first few minutes. Thereafter, the varnish 4 is cured by holding the stator assembly 10 at 160 ° C. for 30 minutes to obtain the stator 15 shown in FIG.
- the stator winding 22 is configured using the winding assembly 30 shown in FIG.
- the winding assembly 30 is manufactured by arranging 12 continuous conductor wires 31 made of an insulated copper wire at a pitch of one slot on the same plane and folding them together. As shown in FIG. 9, each continuous conductor wire 31 is formed by bending a straight part 31 a connected by a turn part 31 b into a planar pattern arranged at a six-slot pitch (6P). ing. The adjacent straight portions 3 la are shifted by the width (W) of the continuous conductor wire 31 by the turn portion 31.
- the stator assembly 20 is preheated to 150 ° C. in a drying furnace, as in the first embodiment. Then, the pre-heated stator la solid 20 was taken out of the drying oven, and the viscosity at 100 ° C. was adjusted to 22 mPas as shown in FIG. Varnish 4 and stator assembly 20 around axis A
- the varnish viscosity at 100 ° C. is adjusted to be 22 mPa ⁇ s, so that the varnish 4 is coiled similarly to the first embodiment. It is possible to manufacture the stator 25 in which 22 2 f and 22 r are filled at a high filling rate.
- the stator winding 22 is formed by the winding assembly 30, the coil ends 22 ⁇ and 22r are formed by arranging the turns 31b in the circumferential direction. Therefore, the varnish 4 penetrates smoothly into the coil ends 22 f and 22 r from the gap between the turn portions 31 b, and the occurrence of air accumulation can be reduced. Then, the heat generated in the turn portion 3 lb is transmitted to the outer peripheral surfaces of the coil ends 22 f and 22 r via the varnish 4 and is effectively cooled by the cooling air. As a result, an excessive rise in temperature of the coil ends 22 f and 22 r is suppressed, and the output of the stator 25 is increased.
- partition plate 24 only needs to have electrical insulation and heat resistance, and for example, glass epoxy resin or nylon can be used. Industrial applicability
- the method for manufacturing the stator of the rotating electric machine according to the present invention includes the steps of: Since the impregnated end is impregnated at a high filling rate, the insulation and electrical corrosion resistance of the stator windings are enhanced, and the rigidity of the entire stator is increased. It is useful as a method for manufacturing a stator of a rotating electric machine such as an AC generator.
