Abstract
The utility model discloses an armature structure for a motor. The armature structure comprises a circular iron core and an armature winding, wherein the armature winding is arranged on the circular iron core in a circular array; the circular iron core comprises an inner iron core ring and an outer iron core ring, the armature winding is arranged between the inner iron core ring and the outer iron core ring in the circular array, and embedding slots used for clamping the armature winding are arranged on both the inner iron core ring and the outer iron core ring. The armature structure for the motor can be used for improving the controllability of the armature of the motor, and can be applied to wind-driven generators.
Description
Technical field
The utility model relates to a kind of motor, particularly relates to a kind of armature of motor.
Background technology
Prior art such as China Patent No. are 200520074351.3, name is called the Chinese patent of " efficient ultra-low speed wind-driven generator ".This technology discloses a kind of generator armature structure.Armature comprises that a ring set is fixed on the big iron core on the stator axis in this structure, in the periphery of big iron core the coil windings that radial array is arranged is installed into.
This structure is because coil windings just is fixed on the outer surface of the big iron core of ring-type by the bottom, because big iron core causes its controllability poor away from rotor magnetic steel.
The utility model content
Technical problem to be solved in the utility model is: a kind of armature structure is provided, is used for improving the controllability of above-mentioned armature.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of armature structure, comprise ring-type iron core and armature winding, and the armature winding circular array is arranged on the annular core; Described annular core comprises interior ring of iron core and iron core outer shroud, and described armature winding circular array is arranged between interior ring of iron core and the iron core outer shroud, is equipped with the embedded groove that is used to block armature winding on ring and the iron core outer shroud in iron core.
Preferably: described armature winding comprises winding iron core, and the winding iron core two ends are equipped with groove; Be provided with and the corresponding attached groove of described groove in the embedded groove in described iron core on ring and the described iron core outer shroud.
Preferably: described armature winding is divided into three strings, and the formation phase difference is 120 ° three phase windings; Be in the same place by the resin mixture plastic packaging by ring-type iron core and armature winding.
The beneficial effects of the utility model are:
Compared to existing technology, the utility model has increased an iron core outer shroud in the outer end of spoke-like coil windings, this iron core outer shroud can be used for fixing coil windings on the one hand, on the other hand because the iron core outer shroud is nearer apart from the rotor magnetic steel distance, the magnetic field that produces in it is easier to interact with magnetic field rotor, can bring stronger controllability and answering property of speed like this.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A portion enlarged drawing among Fig. 1.
Fig. 3 is the structure chart of coil windings.
Embodiment
The utility model provides a kind of armature structure.This armature structure comprises ring-type iron core and armature winding, and the armature winding circular array is arranged on the annular core.Annular core comprises interior ring of iron core and iron core outer shroud, and the armature winding circular array is arranged between interior ring of iron core and the iron core outer shroud, is equipped with the embedded groove that is used to block armature winding on ring and the iron core outer shroud in iron core.
Example structure of the present utility model is referring to illustrated in figures 1 and 2.Ring 4 is fixed on the stator axis 8 in the iron core, and the outer surface of ring 4 has some embedded grooves 5 in iron core, and armature winding 1 the inner is inserted in the embedded groove 5 and circular array is arranged in ring 4 outer surfaces in the iron core, in the embedded groove of the outer end insertion iron core outer shroud 2 of armature winding 1.Referring to Fig. 3, be equipped with groove 7 in the top and bottom of winding iron core 3, in embedded groove 5, be provided with and the corresponding attached groove 6 of groove; During the fixed armature winding, only need one pin inserted by getting final product in the synthetic hole of groove and attached groove.
Armature winding is divided into three strings, and the formation phase difference is 120 ° three phase windings.Be in the same place by the resin mixture plastic packaging by ring-type iron core and armature winding.
Claims (3)
