1, the end winding ventilation and heat is not good, causes that electric machine temperature rise is high, efficient is low, useful life is short;
2, when the breakage of magnet steel polarity wrongly installed or magnet steel occurring, be not easy to change;
3, complex structure, consumption material is many, and cost is high.
The rotor coil holder is unusual important spare part in generator amature, is used for installing the fixed rotor coil.2 utmost point synchronous alternating-current generators, rotor speed up to 3000 turn/per minute and 3600 turns/per minute, to produce larger centrifugal force in rotor high-speed running coil end, throw away under centrifugal action in order to prevent end winding, and require the pillar on the coil holder must have sufficient intensity to block end winding.Simultaneously, generator at work, rotor temperature rise is higher than stator.In order to reduce electric machine temperature rise, raise the efficiency, prevent that end winding from throwing away under centrifugal action, must improve motor internal ventilation and heat condition and possess sufficient intensity.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of salient pole type synchronous alternating-current generator rotor coil holder, has advantages of that materials are few, result of ventilating heat dissipation is good, electric machine temperature rise is low.
The utility model 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 the coil holder body, this coil holder body comprises an axle sleeve, four coil grooves and two magnetic pole sections, parallel standing is provided with six blades on the lateral surface of described coil holder body, and described six blades are located on the two magnetic pole sections in twos relatively; The cross section of every described blade all has long limit and a minor face, and this minor face arranges towards the neighboring of magnetic pole section.
Preferably, be formed with a truncation limit on the neighboring of every described magnetic pole section, and the truncation limit of two magnetic pole sections is symmetrical arranged take the perpendicular bisector of described coil holder body as symmetry axis.
Preferably, be equipped with one first convex tendon on every described magnetic pole section and between the blade in centre position and described axle sleeve.
Preferably, every described coil groove all is equipped with one second convex tendon corresponding to the notch place of coil holder body lateral surface, and the top of this second convex tendon is consistent with the residing elevation of water in the top of described the first convex tendon.
The beneficial effects of the utility model are:
(1) the motor internal result of ventilating heat dissipation is remarkable, decrease electric machine temperature rise, temperature rise ratio uses existing coil holder to reduce by 27%～31.4%, Effective Raise electric efficiency;
(2) saved material, reduced cost, weight of the present utility model is about 60% of existing coil holder weight;
(3) intensity is high, simple in structure, unique outlook, novelty, attractive in appearance;
(4) be convenient to magnet steel and install or change, improved operating efficiency.
[description of drawings]
The utility model 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 the utility model salient pole type synchronous alternating-current generator rotor coil holder.
Fig. 3 is the rearview of the utility model salient pole type synchronous alternating-current generator rotor coil holder.
[embodiment]
See also 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 an axle sleeve 11, four coil grooves 12 and two magnetic pole sections 13; Parallel standing is provided with six blades 15 on the lateral surface 14 of described coil holder body 1, and described six blades 15 are located on the two magnetic pole sections 13 in twos relatively; The cross section of every described blade 15 all has long limit 151 and a minor face 152, and this minor face 152 arranges towards the neighboring of magnetic pole section 13, so design, so that the sagittal plane of described blade 15 is wider, but blade 15 is less with the outside, coil (not shown) end contact-making surface, it is high that this structure has brought up six blades, 15 radial strengths, can prevent that end winding from outwards throwing away under centrifugal action, the lateral surface of coil is exposed in air substantially so that heat radiation, and when rotor high-speed turns round, blade 15 will play the effect of fan, improve the result of ventilating heat dissipation of motor internal.
