Abstract
The utility model relates to a damping ring structure of a salient pole synchronous motor. The damping ring structure comprises a magnetic pole supporting plate, damping bars, damping rings, bolts, nuts, gaskets, a connecting plate and bolts, wherein the magnetic pole supporting plate is connected with a magnetic pole iron core by the aid of a screw, the bolts are used for connecting each two adjacent damping rings, the damping rings are horizontal relative to a rotating shaft, the surfaces of the damping rings are provided with through grooves, the damping bars are placed in the through grooves after penetrating through the magnetic pole iron core and are firmly welded with the damping rings through silver solder, and the damping rings are connected in pairs through the bolts and finally fixed between two magnetic poles and on a rotator support. By the aid of the damping ring structure, bending deformation of damping windings of the synchronous motor in the manufacturing process can be eliminated, and the problems of high local temperature rise, open welding and the like easily occurring in starting of the motor can be solved.
Description
Technical field
The utility model relates to a kind of motor damping ring structure, especially a kind of salient-pole synchronous motor damping ring structure.
Background information
At present, the damping ring structure of known protruding level synchronous motor is to be formed by connecting on damping ring, amortisseur bar, connecting plate, brace, bolt, nut and pad.Amortisseur bar passes pole core, inserts in the damping ring, and damping ring is vertical with respect to rotating shaft, and damping ring connects in twos, forms damping winding.This method is easy to realize at little seat No. and motor progression for a long time, but in the motor of big seat No. and 8 grades, 10 grades, 12 grades, distance is far away between two adjacent poles; Be easy to flexural deformation in the manufacture process; And damping ring is vertical, and contact area is less relatively between amortisseur bar and the damping ring, when motor is done asynchronous starting; Starting current is big, be prone to cause local temperature rise high, problem such as snap.
Summary of the invention
For overcome the local temperature rise that is prone to cause in the damping ring flexural deformation and start-up course in the existing structure manufacture process high, problem such as snap, the utility model provides a kind of motor damping ring structure, this structure is not only easy to make, and can address the above problem.
The utility model solves the technical scheme that its technical problem adopted: damping ring is horizontal with respect to rotating shaft; Groove is opened on the surface; After amortisseur bar passes pole core, be positioned in the groove, weld with silver solder and damping ring; Connect in twos with bolt between the damping ring, be fixed between two magnetic poles at last, on the rotor field spider.And be easy to assembly, the processing boss concentric on the pole end-plate with damping ring, boss stays top wire hole.
The technique effect of the utility model is: when the motor asynchronous starting, because amortisseur bar and damping ring contact area increase, and problem such as better solved above-mentioned local temperature rise height, snap.Connect in twos with bolt between the damping ring, can reduce to make and the motor rotary course in flexural deformation.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment is shown in Fig. 1-3: a kind of 12 grades of grinding machines are with damping ring structure between the synchronous motor magnetic pole; Comprise the collar cheek 4 that links together with pole core 2 usefulness screw rods 6; Bolt 9, nut 14, plain washer 12, spring washer 13, connecting plate 11 and the bolt 10 used when connecting with the damping ring of amortisseur bar 3 joint welding 7, two adjacent damping rings 7.
During installation, when damping ring 7 weld pole core 1 in amortisseur bar 3, with screw 8 damping ring 7 and amortisseur bar 3 are held out against earlier, begin then to weld with silver solder, after welding with screw 8 back-out (like Fig. 2); Damping ring 7 stretches out that pole core 2 parts are straight, and connecting plate 11 is all put on two planes well up and down, and with bolt 9, nut 14, packing ring 12,13 with above-mentioned damping ring 7 and connecting plate 11 fastening (like Fig. 3), be screwed in the rotor field spider 1 through bolt 10 and nut 14.
