Abstract
The utility model discloses a novel generator stator winding. The novel generator stator winding comprises a plurality of silicon steel sheets; each of the silicon steel sheets comprises a plurality of inner groove teeth and a plurality of outer groove teeth; positions of the plurality of the inner groove teeth correspond to positions of the plurality of the outer groove teeth in a radial direction; a gap between each two of the inner groove teeth forms an inner clamp groove towards the center of a circle; a gap between each two of the outer groove teeth forms an external clamp groove towards the center of the circle; and the plurality of the silicon steel sheets with the same structure are overlapped so that a stator of a generator is formed. According to the utility model, use rate of changing magnetic field in each of the silicon steel sheets is improved; in a traditional silicon steel sheet of a stator of a generator, only the magnetic field clinging to a winding coil participates in power generation, and there are not winding coils on two sides and outer sides, so power generation is failed; and the changing magnet field in the silicon steel sheets are fully used for generating current, so on the premise of unchanged input power, intensity of power generation current is directly improved.
Description
Technical field
The utility model relates to a kind of stator structure of generator.
Background technology
At present, in common various generators, stator winding forms by the slotted silicon steel sheet group of interior endless belt and enamelled wire (or copper bar), enamelled wire is stuck in the fluting of silicon steel sheet by the rule of appointment, its common feature is, the draw-in groove of silicon steel sheet is all towards center of circle direction, and effective generating position of enamelled wire all is stuck in the inside of the draw-in groove towards center of circle direction of silicon steel sheet.This method of winding stator has kept wire to be parallel to magnet rotor, and wire can " cutting magnetic line " be generated electricity.Simultaneously, this high permeability material of silicon steel sheet, improve the generator generating efficiency aspect play vital effect, if there is no the support of silicon steel sheet as enamelled wire, and use non-magnet material as support, the sending electric current and will reduce of generator.
It is worth mentioning that, the magnetic line of force silicon steel sheet the inside by by silicon steel sheet, retrained fully, be the magnetic field passed through, silicon steel sheet the inside not and form cutting magnetic line between stator coil, and silicon steel sheet can only rely on the inner continually varying of silicon steel sheet magnetic field to make stator coil produce induced current to the enhancing of generating efficiency.This point, be consistent with the principle of the secondary coil generation current of transformer, all meets maxwell's Theory of Electromagnetic Field.
On the basis that the generator unit stator winding magnetic line of force is analyzed, when can know when adjacent two teeth of silicon steel sheet respectively the N level by rotor and S level by inference, in the silicon steel sheet in two teeth groove root C districts that have the magnetic line of force to pass through, the magnetic line of force quantity of passing through equates with the magnetic line of force quantity that two tooth A and B district pass through separately.There is variation magnetic field in the silicon steel sheet inside in C district in other words, and the magnetic field energy changed produces induced current, can be for generating.From the winding mode of current generator, the C district only has in magnetic field coil one side to utilize, and three sides in addition all do not have to utilize.
The utility model content
In order to improve the generating efficiency of generator, the utility model provides a kind of generator windings, addresses the above problem.
The technical scheme adopted is:
A kind of Novel generator stator winding, comprise a plurality of silicon steel sheets, there is a plurality of inside groove teeth and a plurality of water jacket tooth on each silicon steel sheet, a plurality of inside groove teeth and a plurality of water jacket tooth be the position correspondence diametrically, gap between a plurality of inside groove teeth forms the inner card cage towards center of circle direction, and the gap between a plurality of water jacket teeth forms the exterior bayonet slot that leaves center of circle direction.A plurality of silicon steel sheets with same structure overlap and form the stator of generator.
The utility model is compared with the conventional electric generators winding, has following useful technique effect:
1, improved the utilance to variation magnetic field in silicon steel sheet, the magnetic field in the conventional electric generators stator silicon steel plate only be adjacent to winding coil subparticipation generating, both sides and the outside all do not have winding coil, do not play the generating effect; The variation magnetic field that generator windings method of the present utility model takes full advantage of in silicon steel sheet produces induced current, in input power, under constant prerequisite, has directly improved generation current intensity.
2, there is more loop length to participate in power generation process, in traditional generator windings, it is not participate in generating that a large amount of wires are arranged between draw-in groove, and generator windings described in the utility model makes and participate in the generation induced current more than 98% directly in the wire between draw-in groove, and then improved the capacity factor of electricity generator stator coil.
3,, under the precondition that does not increase input mechanical energy, improved the generating efficiency of generator.
The accompanying drawing explanation
Fig. 1 is the generator unit stator silicon steel sheet schematic diagram that the utility model proposes.
Embodiment
A kind of Novel generator stator winding, comprise on silicon steel sheet 1, silicon steel sheet 1 and there is a plurality of inside groove teeth 3 and a plurality of water jacket tooth 4, a plurality of inside groove teeth 3 and a plurality of water jacket tooth 4 be the position correspondence diametrically, gap between a plurality of inside groove teeth 3 forms the inner card cage 2 towards center of circle direction, and the gap between a plurality of water jacket teeth 4 forms the exterior bayonet slot 5 that leaves center of circle direction.The silicon steel sheet 1 of a plurality of same structures overlaps and forms the stator of generator.
The generator unit stator winding method for winding proposed according to the utility model, after the generator unit stator enamelled wire enters corresponding draw-in groove, in this draw-in groove once around the number of turn of enough expectations, then leave this draw-in groove and enter corresponding next draw-in groove, direction according to the rules, once around the number of turn of enough expectations, repeat above operation until the winding completed in the draw-in groove of each regulation completes in this draw-in groove.Before the winding of each draw-in groove starts to be wound around, note processing doing the insulation bed course between enamelled wire and silicon steel sheet.
After coil independence coiling in each draw-in groove of generator unit stator winding that the utility model proposes completes, the relation between the coil on each phase sequence can be connected in series, and also can be connected in parallel.
The generator unit stator winding silicon steel sheet water jacket tooth 4 that the utility model proposes is higher than silicon steel sheet inside groove tooth 3, the space of silicon steel sheet exterior bayonet slot 5 is greater than the space of silicon steel sheet inner card cage 2, make when winding coil in silicon steel sheet inner card cage 2 when full, a part of space is also left in silicon steel sheet exterior bayonet slot 5 outsides, for fixing between stator and outer cage.
The above is described enforcement of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong to protection range of the present utility model.
