Abstract
The invention discloses a magnetic slot wedge for a motor. The magnetic slot wedge consists of the following components in part by weight: 35 to 45 parts of magnetic component, 25 to 30 parts of epoxy resin, 3 to 5 parts of barium sulfate, 1 to 2 parts of talcpowder and a ZD-1090 liquid modified aromatic amine epoxy resin curing agent in an amount which is adapted to that of the resin, wherein the magnetic component consists of reduced iron powder and reduced nickel powder, and the reduced iron powder to the reduced nickel powder is (1-2):1.
Description
Technical field
The present invention relates to machine field, particularly a kind of motor magnetic slot-seal.
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 magnetic slot-seal, and this magnetic slot-seal 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 magnetic slot-seal; This magnetic slot-seal is made up of following component by weight: 35-45 part magnetic component, 25-30 part epoxy resin, 3-5 part barium sulfate; 1-2 part talcum powder, the liquid modified aromatic amine epoxy curing agent of ZD-1090 that adapts with amount of resin.
Preferably, said magnetic component is made up of reduced iron powder and reduced nickel powder, reduced iron powder: reduced nickel powder is 1-2: 1, and the granularity of reduced iron powder and reduced nickel powder is less than 200 orders.
Preferably; This magnetic slot-seal is made up of following component by weight: 38-42 part magnetic component, 26-28 part epoxy resin, 3.5-4.5 part barium sulfate; 1.2-1.8 part talcum powder, the liquid modified aromatic amine epoxy curing agent of ZD-1090 that adapts with amount of resin.
Most preferably, this magnetic slot-seal is made up of following component by weight: 40 parts of magnetic component, 27 parts of epoxy resin, 4.0 parts of barium sulfate, 1.5 parts of talcum powder, the liquid modified aromatic amine epoxy curing agent of ZD-1090 that adapts with amount of resin.
Magnetic slot-seal of the present invention has following beneficial effect:
(1) this magnetic slot-seal permeability is high, split resistance is high, bending strength is big, owing to adopt the composite magnetic component, can improve electric efficiency 3.5-4.5%, and temperature rise on average descends 15-20 ℃, improves the noise and the vibration of motor, prolongs the useful life of motor.
(2) add talcum powder and barium sulfate, improved slot wedge intensity.
