The production method of the magnetic slot wedge comprises the following steps of: firstly, preparing the unsaturated polyester resin, the internal releasing agent and peroxide initiators into an adhesive; secondly, heating a die and raising the temperature to be 150-200DEG C, wherein the drawing speed is 0.8-1.40r/min; thirdly, carrying out pultrusion on the alkali-free glass fiber impregnated with the adhesive through the die; fourthly, cooling and cutting the slot wedge; fifthly, grinding the cut slot wedge; sixthly, treating the surface of the slot wedge with paint to realize smoothness and burr freeness; and seventhly, air-drying, detecting and packaging the slot wedge. The magnetic slot wedge has the advantages of high magnetic permeability, high split resistance and high bending resistance as well as is simple in production method.
Description
Technical field
The present invention relates to a kind of magnetic slot-seal and production method thereof, it is unshakable in one's determination that this magnetic slot-seal is mainly used in big-and-middle-sized ac high-voltage motor stator.
Background technology
Big-and-middle-sized ac high-voltage motor is owing to the requirement of insulation and manufacturing process, and stator winding adopts formed coil, and the iron core of stator is processed open slot.Because the opening of groove can cause the aggravation of teeth groove magnetic resistance change rate, the air gap flux density skewness has increased the air-gap permeance slot ripples, thereby causes the motor exciting curent to increase, and rotor surface loss and pulsation loss increase, and causes electric machine temperature rise to increase decrease in efficiency.In big-and-middle-sized ac high-voltage motor, adopt common slot wedge to address the above problem; Must adopt magnetic slot-seal at the stator openings groove; To alleviate the influence that groove distributes to air-gap field; Make that the close distribution of magnetic is tending towards evenly in the air gap, the open slot motor just can obtain the such electromagnetic property of semi-open slot or semi-enclosed slot.Magnetic slot-seal permeability of the prior art is lower, and does not have enough mechanical strengths, can't satisfy the requirement of long-term use.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of prior art and magnetic slot-seal and the production method thereof that a kind of permeability is high, split resistance is high, bending strength is big is provided.
The technical scheme that the present invention solves the problems of the technologies described above employing is this magnetic slot-seal; Its characteristics are: comprise 943 unsaturated polyester resins, inner pattern releasing agent applicable, peroxidized t-butyl perbenzoate, dibenzoyl peroxide, increase magnetic material and alkali-free glass fibre; The said components percentage by weight is 943 unsaturated polyester resin 18%-20%, inner pattern releasing agent applicable 0.5%-1%, peroxidized t-butyl perbenzoate 0.2%-0.5%, dibenzoyl peroxide 0.1%-0.3%, increases magnetic material 54%-57%, alkali-free glass fibre 24%-25%.
The magnetic material that increases of the present invention is a reduced iron powder.
Each composition weight percentage of the present invention is 943 unsaturated polyester resins 18.3%, inner pattern releasing agent applicable 0.51%, peroxidized t-butyl perbenzoate 0.28%, diphenyl peroxide first 0.16%, reduced iron powder 56.53%, alkali-free glass fibre 24.22%.
The production method of magnetic slot-seal of the present invention, its characteristics are: may further comprise the steps, (1) is mixed with adhesive to unsaturated polyester resin, inner pattern releasing agent applicable, peroxide initiator in proportion; (2) heating mould is warming up to 150 ℃-200 ℃, pulling speed 0.8-1.40r/min; (3) pass through the mould pultrusion to the alkali-free glass fibre of dipping adhesive; (4) cooling, cutting; (5) slot wedge to well cutting carries out bistrique; (6) slot wedge surface paint is handled, made it bright and clean no burr; (7) dry, detect, pack.
The present invention compared with prior art has the following advantages: said magnetic slot-seal adopts reduced iron powder to do magnetic material, adopts the pulling moulding process; Therefore permeability is high.The mechanical strength of resin that said magnetic slot-seal adopts is higher, temperature, two kinds of initators of high temperature in the process using, and two stage solidification, so intensity is good.Relative permeability under the magnetic field intensity 1000Oe is more than or equal to 3.2, and more than or equal to 800MPa, the bending strength under the normality can effectively reduce the motor iron loss more than or equal to 200MPa to split resistance (N/10mm is long), improves electric efficiency, reduces electric machine temperature rise.Its production method is simple, can reach the high strength high permeability, is convenient to execute-in-place control again.
