Abstract
The invention enables a sealing agent such as resin to be filled in gaps of a tooth portion and an insulating material so as to improve strength of iron core sheets. An iron core structure includes that when a plurality of iron core sheets rotate, the sealing agent such as the resin is filled in the gaps formed by the tooth portion and the insulating material and hardened so as to enhance the strength of an iron core and fix the insulating material and coils.
Description
Technical field
The present invention relates to motor iron core structure, injection is only sealed agent and is made its sclerosis between the space that especially forms between the tooth portion of laminated iron core and the insulating material, in order to increase the new improvement of the intensity that mutually combines between coil and insulating material and the iron core.
Background technology
The motor iron core before used structure, generally be, in the tooth portion of cores pile in layers, coil is set between between insulating material, only seal that agent etc. forms thereby coat resin in the outside of this coil.
Motor iron core structure before is because constitute according to above-mentioned principle, so the problem below existing.In other words, unfixing because insulating material just is embedded in the tooth portion of iron core, just to fix with only sealing agent in the outside of coil, insulating material and iron core are not to be fixed on together, and be not enough for the mechanical strength of whole iron core.
Summary of the invention
Goal of the invention: this invention is in order to overcome the above problems; Especially; The feasible sclerosis of agent is only sealed in injection in the space that forms between the tooth portion of the iron core of lamination and the insulating material, makes the intensity that mutually combines of coil and insulating material and iron core obtain increasing, and the motor iron core structure of high rigidity is provided.
Technical scheme: the motor iron core according to this invention is; The colyliform lamination that has plurality of pins portion changes long-pending according to direction of principal axis; In above-mentioned each tooth portion coil is set between between insulating material; Inject between the space that forms between above-mentioned insulating material and the above-mentioned tooth portion and only seal agent and make its sclerosis, also have, the portion of owing is cut and the structure that forms by what the side of above-mentioned tooth portion formed in above-mentioned space.
Beneficial effect: motor iron core structure of the present invention is to be made up of above-mentioned principle, has following effect.In other words, in the gap of the tooth portion of iron core and insulating material, inject sealing agents such as resin, make each lamination and insulating material and coil reach the effect of integrated curing, reach the structure higher than former strength rigid.

Embodiment
Below, description of drawings is according to the example of the suitable electric machine iron core structure of this invention.
Fig. 1 is a punching press colyliform lamination 1, is formed by a plurality of outside tooth portions 2.In the side of the tooth portion 2 of above-mentioned lamination 1, the portion of owing 3 is cut in formation as shown in Figure 2.As shown in Figure 3 with a plurality of laminations 1 by in the tooth portion 2 according to direction of principal axis revolution stack, that is, and the revolution superimposed structure of saying usually, thereby form that revolution as shown in Figure 4 superposes decide the iron core 10 of thickness.
Above-mentioned iron core 10 is not provided with coil 11 etc. in Fig. 4, be actually as shown in Figure 2, and the coil 11 of insulating material 12 is smeared in the periphery in tooth portion 2, makes insulating material 12 form gap 13 with 2 in tooth portion because of the above-mentioned portion of owing 3 of cutting like this.In above-mentioned gap 13, the sealing agent 14 that injects molten resin etc. is only to seal agent etc. and form by coat resin in the outside of above-mentioned coil 11.
Above-mentioned sealing agent 14 makes its sclerosis after handling through inject or smear etc., make to strengthen solidification effect between tooth portion 2 and insulating material 12 and the coil 11, makes iron core 10 whole increasing solidify rigidity.
In addition, above-mentioned gap 13 not only can the portion of owing 3 forms through cutting, and also can form through recess, also can form because of deliberately cause bad.In addition, this gap 13 can form through each tooth portion 2, also can have only a tooth portion 2 to form.
Claims (2)
1. a motor iron core is constructed; It is characterized in that: a plurality of colyliform laminations (1) with tooth portion (2) are according to direction of principal axis revolution stack; In above-mentioned each tooth portion (2) coil (11) is set between between insulating material (12), injection is only sealed agent (14) and is made its sclerosis between the space (13) that forms between above-mentioned insulating material (12) and the above-mentioned tooth portion (2).
2. motor iron core according to claim 1 structure is characterized in that: the portion of owing (3) of cutting that forms according to the side of above-mentioned tooth portion (2) forms above-mentioned space (13).
