Abstract
The present invention relates to the formation method of a kind of soft magnetism slot wedge and soft magnetism slot wedge, be to constitute by magnetic component and resin Composition, and be formed at leave slotted eye on the motor stator and rotor and arrange coil after remaining notch place, the present invention can be used for various large, medium and small and micromachine, can change the magnetic loss of motor internal, saves energy can reach 2.4%.
Description
The present invention relates to magnetic material, and the method that on the notch of the stator and rotor of motor, forms slot wedge with this material, this material mainly is made up of magnetic component and resin Composition.
As everyone knows, motor must be left slotted eye for electric energy is converted into mechanical energy on stator and rotor, and in groove, arrange coil, but because the existence of notch has caused groove tooth effect in motor, this has just produced the energy consumption of motor self, lower efficiency, and bring such as temperature rise and increase, a series of problems such as noise increasing, the lost of life are in order to reduce the motor own loss, raise the efficiency, will reduce groove tooth effect.Along with science and technology development, the motor that household electrical appliance use is increasing, and the production of this class motor and the reducing energy consumption of old motor are problems anxious to be solved.
In addition,, can not all change for the moment, not find effective conservation measures again for large quantities of existing old motors though occurred new and effective motor in recent years.
The object of the present invention is to provide and a kind ofly overcome above-mentioned shortcoming and reduce the soft magnetic material of groove tooth effect and the slot wedge that utilizes this soft magnetic material to make.This slot wedge is particularly suitable for small-sized and installation micromachine, simultaneously, for the various losses of large-size machine reduce have outstanding effect.
In the present invention, the slot wedge magnetic material comprises magnetic component and resin Composition, and wherein magnetic component accounts for the 70-87% of gross weight, and it is to be higher than 200 purpose iron powders, contains ferrosilicon powder, ferrite powder or silicon steel powder; Resin Composition accounts for gross weight and is not less than 13%, this resin can be epoxy resin and with ethylenediamine or triethylene tetramine as curing agent; Can also containing in this resin Composition changes solidifies stupid dioctyl phthalate fourth two fat of modifier-phosphorus of the toughness of back soft magnetic material, and its content is not higher than 6%.
Utilize the notch on the above-mentioned soft magnetic material sealing motor of the present invention, form the method for soft magnetism slot wedge, be notch place with this applying material remainder after leaving slotted eye on the stator and rotor and arranging coil, the sealing notch, thus realization reduces the purpose of groove tooth effect.The uniform magnetic material that uses in this method comprises magnetic component, resin Composition and resin curing agent and modifier.Spread upon above-mentioned magnetic material in the notch and make it and solidify.The normal temperature cure time of this magnetic material is about 6 hours, thereby forms slot wedge.
Utilize magnetic material system magnetic slot-seal of the present invention, be used to seal and arrange remaining notch behind the coil in the slotted eye opened on the stator and rotor.
The present invention is further described below in conjunction with embodiment.
The invention is not restricted to following embodiment, substituting and changing of any those skilled in the art known technology all allows.As according to the magnetic material difference of variety classes motor, the different ratios of adjusting each component of soft magnetic material of magnetic permeability, make the consistent of its magnetic permeability and motor material, reach optimum efficiency; And this magnetic material should have minimum coercive force; In addition, also available mechanism's intensity that the back magnetic material is solidified in change such as chemical fibre, also available chemical industry solvent or diluent diluted magnetic material.
Fig. 1 is the schematic cross section that soft magnetism slot wedge of the present invention is used for micro-machine.
Fig. 2 is the schematic cross section that soft magnetism slot wedge of the present invention is used for large-size machine.
Embodiment 1:
Using during the small-sized or micromachine of this soft magnetism slot wedge produces, as shown in Figure 1, after arranging coil 2 in the slotted eye of wherein leaving on stator or the rotor 1, on notch place coil 2, dispose insulating barrier 3 and soft magnetism slot wedge 4, magnetic component accounts for 80.5% resin Composition and accounts for 19.5% in this soft magnetic material, and wherein modifier content is 5.5%, and epoxy resin content is 14.0%, in the present embodiment, small-sized or micromachine can economize on electricity 2.4%.
Embodiment 2:
In this soft magnetism slot wedge of use, in the large-size machine, as shown in Figure 2, after wherein arranging coil 2 in the slotted eye of leaving on stator or the rotor, on notch place coil 2, dispose insulating barrier 3, dispose fiber cloth 5 and silicon steel sheet 6 on the insulating barrier 3, soft magnetism slot wedge 4 is arranged on silicon steel sheet 6, magnetic component accounts for 80.5% in this soft magnetic material, resin Composition accounts for 19.5%, and wherein epoxy resin accounts for 17%, and modifier accounts for 2.5%.In the present embodiment, large and medium-sized motor can economize on electricity 2.2%.
Embodiment 3:
In Fig. 1, magnetic component is with after resin Composition evenly mixes, before resin solidification, spread upon on the insulating barrier 3 on slotted eye 1 interior loop 2, form soft magnetism slot wedge 4 behind the resin solidification, wherein magnetic component can be an iron powder, contain ferrosilicon powder, ferrite powder or silicon-steel powder, preferably silicon content is the ferrosilicon powder that contains of 0.2-5%.
In Fig. 2, configuration insulating barrier 3 on slotted eye 1 interior loop 2, fiber cloth 5 and silicon steel sheet 6, magnetic component spreads upon before resin solidification on the silicon steel sheet 6 with after resin Composition evenly mixes, formation soft magnetism slot wedge 4 behind the solid.
The invention is not restricted to the foregoing description, the replacement of any those skilled in the art known technology is also fair puts.
