[background technology]
Small-sized salient pole type 2 pole synchronous alternating-current generator rotor coil holder is integral type, heatproof, enhancement mode compression moulding part.Existing salient pole type synchronous alternating-current generator rotor coil holder 100' as shown in Figure 1, on coil holder lateral surface 14', every polar curve circle (not shown) end outer fix arranges 5 ~ 8 square column 15', and between whole row's column 15', and both sides coil groove 12' lateral wall couples together and forms enclosing wall type structure, end winding, side and bottom and coil holder 100' are close together, its object is to: when preventing rotor high-speed from operating, end winding throws away under centrifugal action; In addition, the neighboring of existing rotor coil holder 100' two pole segment 13' is arc, and conform to rotor core polar arc shape, the coil holder of this kind of structure exists following shortcoming:
1, end winding ventilation and heat is not good, causes that electric machine temperature rise is high, efficiency is low, useful life is short;
2, when occurring that magnet steel polarity is wrongly installed or magnet steel is damaged, be not easy to change;
3, complex structure, consumption material is many, and cost is high.
Rotor coil holder is unusual important spare part in generator amature, for installing fixed rotor coil.2 pole synchronous alternating-current generators, rotor speed is up to 3000 rev/min and 3600 rev/min, larger centrifugal force being produced in rotor high-speed running coil end, in order to prevent end winding from throwing away under centrifugal action, requiring that the pillar on coil holder must have sufficient intensity to block end winding.Meanwhile, at work, rotor temperature rise is higher than stator for generator.In order to reduce electric machine temperature rise, raising the efficiency, preventing end winding from throwing away under centrifugal action, motor internal ventilation and heat condition must be improved and possess sufficient intensity.
[summary of the invention]
Technical problem to be solved by this invention is to provide a kind of salient pole type synchronous alternating-current generator rotor coil holder, has the advantage that materials are few, result of ventilating heat dissipation is good, electric machine temperature rise is low.
The present invention solves the problems of the technologies described above by the following technical programs: a kind of salient pole type synchronous alternating-current generator rotor coil holder, comprise coil holder body, this coil holder body comprises an axle sleeve, four coil grooves and two pole segment, parallelly on the lateral surface of described coil holder body be equipped with six blades, and described six blades are located in two pole segment between two relatively; The cross section of every described blade all has a long limit and a minor face, and this minor face is arranged towards the neighboring of pole segment; The neighboring of every described pole segment is formed with a truncation limit, and the truncation limit of two pole segment with the perpendicular bisector of described coil holder body for symmetry axis is symmetrical arranged.
Preferably, one first convex tendon is equipped with between the blade in every described pole segment and in centre position and described axle sleeve.
Preferably, every described coil groove corresponds to the notch place of this outside of coil holder and is all equipped with one second convex tendon, and elevation of water residing for the top of the top of this second convex tendon and described first convex tendon is consistent.
Beneficial effect of the present invention is:
(1) motor internal result of ventilating heat dissipation is remarkable, considerably reduces electric machine temperature rise, and temperature rise ratio uses existing coil holder to reduce by 27% ~ 31.4%, effectively improves electric efficiency;
(2) save material, reduce costs, weight of the present invention is about 60% of existing coil holder weight;
(3) intensity is high, structure is simple, unique outlook, novelty, attractive in appearance;
(4) be convenient to magnet steel install or change, improve operating efficiency.
[accompanying drawing explanation]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of existing salient pole type synchronous alternating-current generator rotor coil holder.
Fig. 2 is the front view of salient pole type synchronous alternating-current generator rotor coil holder of the present invention.
Fig. 3 is the rearview of salient pole type synchronous alternating-current generator rotor coil holder of the present invention.
[embodiment]
Refer to Fig. 2-3, a kind of salient pole type synchronous alternating-current generator rotor coil holder 100, comprises coil holder body 1, and this coil holder body 1 comprises axle sleeve 11, four coil groove 12 and two pole segment 13, parallelly on the lateral surface 14 of described coil holder body 1 be equipped with six blades 15, and described six blades 15 are located in two pole segment 13 between two relatively, the cross section of every described blade 15 all has long limit 151 and a minor face 152, and this minor face 152 is arranged towards the neighboring of pole segment 13, design like this, make the sagittal plane of described blade 15 wider, but blade 15 is less with contact outside face, coil (not shown) end, it is high that this structure creates six blade 15 radial strengths, can prevent end winding from outwards throwing away under centrifugal action, make the lateral surface of coil substantially in atmosphere exposed so that heat radiation simultaneously, and when rotor high-speed operates, blade 15 will play the effect of fan, improve the result of ventilating heat dissipation of motor internal.
Referring again to Fig. 2-3, the neighboring of every described pole segment 13 is formed with a truncation limit 131, and the truncation limit 131 of two pole segment 13 with the perpendicular bisector of described coil holder body 1 for symmetry axis is symmetrical arranged, the design on truncation limit 131 is convenient to magnet steel (not shown) installation or changes, and again saves raw material simultaneously.
