Abstract
The utility model discloses a generator rotor, comprising a main shaft, a rotor core, a coil and an insulating hoop. The insulating hoop is a steel loop the surface of which is wrapped with an insulating film, and the outer diameter of the steel loop is less than that of the rotor core, and the insulating steel loop is sleeved at the two ends of the rotor core. By adopting the structure, due to that the insulating steel loop is sleeved on the outside ring of the rotor end coil, the steel loop and the coil are in surface contact, which greatly strengthens the mechanical strength of the end of the rotor coil. Therefore, for the end of the coil, the end disassembly of the overall coil is not easy occur, so as to lead the coil to be thrown out of a core trough, prevent generating friction between the rotor and the stator, prevent the generator from being burned down and improve the service life of the generator. In addition, since the outer diameter of the steel loop is less than that of the core, no effect can be generated when the rotor is arranged into the stator, and the friction can be also difficult to generate between the rotor and the stator when the rotor rotates.
Description
Technical field
The utility model relates to a kind of generator amature.
Background technology
Present generator amature is made up of the coil of main shaft, rotor core, stirrup and shaping or coiling, rotor core is contained on the main shaft, and its circumferential outer surface has equally distributed groove, described coil is embedded in the iron core slot, with overhang welding or shaping, stirrup is enclosed within on the end winding then, uses no latitude band or insulation film again end banding, rotor coil intensity is strengthened, and described stirrup is a circular cross-section.At end winding stirrup is set, be to prevent that the centrifugal force that rotor produces when high speed rotating from making coil disengaging rotor and damaging generator, but, guarantee that coil does not break away from rotor, then stirrup needs sufficiently high intensity, because stirrup is a circular cross-section, guarantee that stirrup has enough intensity, then the sectional area ratio of stirrup is bigger, like this, the external diameter of stirrup will be greater than the external diameter of rotor core, can be affected in the time of in rotor is encased in stator, promptly allow to install, when rotor when rotated, stirrup on the rotor core may produce friction with stator inner surface, reduced life of generator, because stirrup is that line contacts with coil, the contact area of stirrup and coil is little again, like this, stirrup is firm inadequately to the banding of coil.
Summary of the invention
The purpose of this utility model provides a kind of generator amature, utilize structure of the present utility model, be convenient to rotor and be installed in the stator, there are enough mechanical strengths the rotor coil end, end winding be difficult for to take place was disintegrated with the induced coil iron core slot of dishing out, the useful life of improving generator.
For achieving the above object, generator amature of the present utility model comprises main shaft, rotor core and coil, and rotor core is located on the main shaft, and its external peripheral surface is provided with groove, and coil is located in the groove of described rotor core; Described rotor core both ends are provided with the insulator bracket cover; Described insulator bracket cover comprises steel band circle and insulation film, and insulation film is wrapped on the steel band circle surface, and the external diameter of described steel band circle is less than the external diameter of rotor core
Adopt this structure, because the outer ring of rotor tip coil is with the steel band circle that is enclosed with insulation film, and the external diameter of steel band circle is less than the external diameter of rotor core, described steel band circle is that face contacts with coil, strengthened the mechanical strength of rotor coil end like this, therefore, when generator when big load impact anticlimax or the loose contact of end winding structure produce high temperature, can make end winding that whole the disintegration so that the coil iron core slot of dishing out be difficult for to be taken place, make rotor and stator not produce friction, to guarantee that generator is not burnt; Because the external diameter of steel band circle is unaffected when then rotor is installed in the stator less than the external diameter of rotor core, when rotor rotated, rotor and stator also were difficult for producing friction, the useful life of having improved generator.
As improvement, described steel band circle is wrapped with temperature-resistant insulation layer, so more can strengthen the mechanical strength of end winding.
As improvement, the quantity of the steel band circle of the every end of described rotor core be arranged side by side more than two or two, adopt this structure, then reduced dipping lacquer and high temperature and cured this procedure, and can guarantee the mechanical strength of end winding.
As concrete structure, described temperature-resistant insulation layer is the high-temperature insulation thin layer.Adopt this high-temperature insulation film, its electric insulating quality is good, solvent resistance, anti-atomic radiation, can at high temperature use for a long time.
As concrete structure, described temperature-resistant insulation layer is no latitude band.Adopt no latitude band, surfacing light, carbon dust resisting excellent adsorption, insulating reliability height behind its parcel.
As concrete structure, described generator amature is a wind power generator rotor.Wind-driven generator generally is to work under the situation of big load impact anticlimax, adds the hoop cover in the generator amature end, has just strengthened rotor coil end mechanical strength greatly, makes end winding be difficult for taking place to disintegrate with the induced coil iron core slot of dishing out.
Compared with prior art, the utility model since the external diameter of steel band circle less than the external diameter of rotor core, it is unaffected when then rotor is installed in the stator, when rotor rotates, rotor and stator also are difficult for producing friction, because what be provided with in the end winding outer ring is the steel band circle, and the steel band circle is that face contacts with coil, therefore, rotor coil end mechanical strength height be difficult for to take place disintegrates with the induced coil iron core slot of dishing out end winding, avoids rotor and stator not to produce friction, to guarantee that generator is not burnt, improved the useful life of generator.
