Abstract
The invention discloses a motor slot wedge which is characterized in that the slot wedge consists of the following components in percent by weight: 14-16% of unsaturated polyester resins, 0.1-0.3% of internal releasing agents, 0.8-1.2% of tert-butyl peroxy benzoates, 0.6-1.0% of dibenzoyl peroxide, 5-8% of talcum powder, 28-30% of alkali-free glass fibers and residual amount of iron-nickel alloy powder.
Description
Technical field
The present invention relates to machine field, particularly a kind of motor slot wedge.
Background technology
Electrical machine energy-saving is the emphasis that people pay close attention to always, more shows its importance in current energy-intensive society.Replace the insulation slot wedge in the motor stator with magnetic slot-seal; The pulsating amplitude of the magnetic flux density of rotor tooth surface when utilizing the magnetic conduction of magnetic slot-seal to be used for reducing the motor operation; Magnetic flux distribution is tending towards evenly, and then reduces the supplementary load loss of motor, improve efficiency of motor.
Magnetic slot-seal is to prepare with permeability magnetic material.Using more at present, permeability magnetic material is magnetic slot mud, iron powder mold pressing permeability magnetic material and iron powder lamination permeability magnetic material.The relative permeability of magnetic slot mud and mold pressing permeability magnetic material is higher, but bending strength and impact strength are lower, and it is higher that permeability magnetic material adds the man-hour percent defective, is applied to often occur coming off and cracking phenomena behind the motor with the magnetic slot-seal of its preparation.
Common glass fiber drawing groove wedge forms with the pulling of fibre glass roving dipping adhesive; Unidirectional intensity is only arranged, as the patent No. be 99112760.9, name is called in the Chinese patent of " magnetic slot-wedge preparation process " and discloses a kind of method that adopts the alkali-free glass spun yarn to prepare magnetic slot-seal.And common slot wedge adopts epoxy to make adhesive, the slot wedge that such technical recipe makes, and intensity is fair under normal conditions, but intensity is relatively poor after being heated.It is unidirectional for present existing glass fiber drawing groove wedge, though its apparent smooth, physical dimension is stable, thickness is even, easy to use, and also tool mechanical electric apparatus performance and thermal endurance preferably.But the unidirectional intensity of its tool, the low only 600N/10mm of split resistance, flexural strength is 200-300Mpa, and owing to use that epoxy, polyamide are made adhesive, toluene is made diluent, causes that volatile content is higher, hot performance descends.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of motor slot wedge, and this slot wedge permeability is high, split resistance is high, bending strength is big.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
A kind of motor slot wedge; This slot wedge is made up of following component by weight percentage: unsaturated polyester resin 14%-16%, inner pattern releasing agent applicable 0.1%-0.3%, peroxidized t-butyl perbenzoate 0.8%-1.2%; Dibenzoyl peroxide 0.6%-1.0%, talcum powder 5%-8%, alkali-free glass fibre 28%-30%, surplus is the iron-nickel alloy powder.
Preferably; Said slot wedge is made up of following component by weight percentage: unsaturated polyester resin 14.5%-15.5%, inner pattern releasing agent applicable 0.15%-0.25%, peroxidized t-butyl perbenzoate 0.9%-1.1%; Dibenzoyl peroxide 0.7%-0.9%, talcum powder 6%-7%, alkali-free glass fibre 28.5%-29.5%, surplus is the iron-nickel alloy powder.
Most preferably; Said slot wedge is made up of following component by weight percentage: unsaturated polyester resin 15%, inner pattern releasing agent applicable 0.20%, peroxidized t-butyl perbenzoate 1.0%; Dibenzoyl peroxide 0.8%, talcum powder 6.5%, alkali-free glass fibre 29%, surplus are the iron-nickel alloy powder.
The present invention has following beneficial effect with respect to prior art:
(1) relative permeability under magnetic field intensity 1000 Oe of the slot wedge of the present invention's preparation is greater than 3.8, and greater than 850MPa, the bending strength under the normality is more than or equal to 240MPa for split resistance (N/10mm is long).Can effectively reduce the motor iron loss, improve electric efficiency, reduce electric machine temperature rise.
(2) said magnetic slot-seal adopts the iron-nickel alloy powder to do magnetic material, so 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.
